As spring unfolds in this part of the world in mid-late April each year, it’s time for the Rochester Mineralogical Symposium!

Of course, the extent to which it’s spring in this region depends on exactly where you are – Rochester was further ahead and this year there was still lots of snow up here in Bancroft. Even so, the first beautiful signs of the new season were emerging. (It has been a cold spring – our furnaces out here have been on still, into June (!)).


Rochester 2019 marked our 46th year.

If you are new to the Symposium, it’s a unique event. It brings together professionals and amateurs, and a complete range of subjects in specimen mineralogy. It is collegial and friendly, meant for collectors and those who love to learn about minerals. The RMS prominently features What’s New in Minerals each year. It is also a mineral show with excellent dealers set up and open when the talks are not on. It may sound scientific and formal, but Rochester is perhaps the most welcoming and inclusive mineral gathering I know. It’s a time for hanging out and having a good time with mineral friends, new and old (of course new people come every year, and if you’ve never been, make 2020 your first!). It’s possible a drink or two is shared among us, and a few mineral songs are always sung.

Rochester is not meant to be a strictly scientific symposium – it is meant for anyone who wants to learn more about minerals. At Rochester, many of the best-known mineral people of our time, mineralogists, curators, collectors (including beginners) and students, all share and learn together.

We had a stellar cast of speakers this year! We began with three talks (Thursday night and Friday morning) about crystals, given by three friends who have been experts in crystallography for a long time.

John Jaszczak, Pete, John Rakovan at the Rochester Symposium, 2019

Three Crystal Rogues. From Left, John Jaszczak, Pete Richards and John Rakovan.

These three talks began with some fundamental questions and concepts, progressed into distortions and ended up teetering on the edge of the crystallography universe – I lightheartedly told our speakers they were taking us on a journey, From Cubes to Tubes.

Thursday Night

John Rakovan started us off with Crystal Growth: A Primer. He explored why it is that crystals form flat faces. It’s such a fundamental question, I’ve never thought to wonder about it (!). It’s easier to assume that we have an understanding of basic crystals if we understand the crystal classes. As a general rule, crystals have flat faces, at a macro level. However, at a microscopic level, crystal faces often display topography that can help us to understand how they grew. The short answer about flat faces is that the mechanism of growth prefers to add thin layers as a crystal grows, completing a flat layer and then beginning the next. The longer explanation as to why that is has to do with the way atoms bond to surfaces – an atom will bond much more easily if it can attach not only to the flat surface underneath, but also a step/bench on one side. If thought of as a cube, if the bottom and one side can be attached, the atom is much more likely to be bonded and stay in place, as is the next, and the next, until the layer has crept all across the crystal. Once a new layer starts, the process is repeated.

but with the right illumination, one can see the stepped growth pattern.

Friday Morning

R. Peter Richards opened Friday morning with a talk on Distorted Crystals. Many of you know Pete is often involved in unravelling some of the most interesting crystallographic mysteries in Mineral World. His presentation took us away from typical flat-faced, simple geometric crystal forms, into the realm of distortions of various kinds. Pete is an engaging speaker and this was a great talk!

John Jaszczak then led us to the brink of the crystallographic abyss, with Criminal Minerals: Investigating Minerals that Break the Law. A subject that could easily descend into a very technical place and lose an audience, but there was no worry of that! Why? Well, other than the fact John is a great presenter in any event… he chose to explain the concepts using photographs of parked cars. Answering once and for all the age-old question (at least I’ve always wondered) can crystallographic issues be solved with parked cars…

Beginning with the illustration of a crystal on the right hand side of this slide…



Explaining, for example, that complications can result in a crystal’s growth when something shows up where it should not, within a crystal’s lattice…


Issuing a wanted-list for criminal minerals the offence of incommensurate modulation…


… you might feel like “incommensurate modulation” is a good technical place to become lost… nope, turns out parked cars can illustrate almost anything, as this one example shows.


OK, one _mineral_ example in photographs. This is cylindrite, a classic, with its cylindrical crystal morphology:



Friday Afternoon – Contributed Papers in Specimen Mineralogy

Friday afternoon at the RMS, we have Contributed Papers in Specimen Mineralogy (we typically refer to it as the “Technical Session”). Our coordinator of this session and editor of the abstracts is Sarah Hanson – she runs the call for papers, and coordinates everything to put this program together. Our call for papers is usually out in December, but start thinking about it now – if you have a paper you’d like to contribute, we’d love to see your submission this year.

The session itself is moderated by Dr. Carl Francis. Friday afternoon is packed with great 15-minute talks on a range of topics, some completely specimen-oriented, some more mineralogical. I never write at length in these blog posts about the Technical Session talks, because the abstracts from the talks are published during the year in Rocks and Minerals magazine (don’t forget to watch for them!) and they are published in the RMS Program Notes (see the links section at the end of this blog post).

However, I do feel strongly about writing a just bit about it. The Technical Session is one of the features of the RMS that makes it unique, with professionals and amateurs all contributing. For collectors, there is a lot of interest in these talks – sometimes about rare or new minerals or finds, sometimes about localities, sometimes about scientific work done to establish fakes in Mineral World. We had a high percentage of truly excellent talks given by students. The group from the Department of Geology and Environmental Earth Science, Miami University, Oxford, Ohio did a particularly outstanding job. Too often, we look around Mineral World and see fewer young people than we’d all like – these students represent a bright future for mineralogy and the science that underpins everything we enjoy in Mineral World.

Friday Night

On Friday night, Terry Huizing gave “The Variety and Appeal of Calcite”. Terry has a superb calcite collection, and this talk was full of photographs of wonderful calcite specimens. He spoke about calcite colours and crystals – with Terry’s presentation, anyone could be tempted to specialize in collecting calcite.

Terry made one point that really struck me – it’s something I had never known about calcite, and I thought it was an awesome bit of mineral learning. Many people know that calcite is known for its huge variety of crystal forms, as over 800 have been described. It’s mind-boggling. I love poring over incredible intricate calcite crystal drawings in Goldschmidt and other publications. Terry pointed out that all of these complex crystals we see are combinations of two or more of only five forms, along with any twinning that may be present: the pinacoid, prism, rhombohedron, scalenohedron and dipyramid. (!) I loved learning that! Terry illustrated these, including some Jeff Scovil photos in the following slides:

Calcite - Pinacoid and Prism


Calcite - Rhombohedron


Calcite - Scalenohedron


Calcite - Dipyramid

Terry’s was mostly a talk comprised of great photos of beautiful specimens, including this wonderful piece.

Rhombohedra and dipyramid

Saturday Morning: What’s New in Minerals and Localities

Saturday morning is always dedicated to What’s New in Minerals – it has been at the heart of the Symposium from the early days, and it is an absolute highlight every year. We divide the morning into Parts I and II.

Jeff Scovil has been leading Part I for 25 years (time flies!), and even after Friday night’s fun takes us all well into the night, this talk is packed every year. Of course it is: this is the world’s great and famous mineral photographer showing us fantastic photos of the most remarkable new things he’s shot over the past 12 months. The jaw-dropping specimens and awesome photos mean this part is full of oooohs and aaaahs. Here are a few highlights from Jeff’s Part I this year:

Part II is led by John Betts – he coordinates the program team and assembles all of what’s new into slides. John then presents some of the material, while other team members speak about the contributions they’ve assembled. This year’s team included Jim Nizamoff, Mark Jacobson and me. Part II is great session, bringing together finds and workings from around the world with photographs of localities and specimens. Of course, our goal is to bring new specimens and stories to light!

I won’t go too far into this, as we covered a lot of ground, but here are a few photos to give a little glimpse, and I’ll finish with a particularly interesting story from Mont St. Hilaire.

John covered finds from all over, and he included some rather interesting new finds from Maine:






The new finds I presented for What’s New have mostly already been posted elsewhere here on my website, including under What’s New Blog and New Specimens.

For example, the beautiful new fluorite specimens from Madagascar:

Fluorite, Mandrosonoro, Ambatofinandrahana, Amoron’i Mania, Madagascar

Fluorite, Mandrosonoro, Ambatofinandrahana, Amoron’i Mania, Madagascar – 11.0 cm
Mary Holdgraf specimen

On a very different note – a new identification – we had a great contribution from Lázló Horváth (thank you Les!). This story goes back to the 2013 approval of marshalsussmanite as a new species (an intermediate species between serandite and pectolite) and the subsequent 2014 Rocks and Minerals magazine article about it. Les wondered if perhaps some of the serandite specimens from Mont St. Hilaire might in fact be marshalsussmanite. In cooperation with the Canadian Museum of Nature, a survey of various Mont St-Hilaire serandites was commenced using several techniques, and a number were found to be in the marshallsussmanite range. Notably, one of them was from the major 1981 find, often associated with Ernie Schlichter. Single crystal structure analysis confirmed that the 1981 bladed serandite was marshallsussmanite. However, there’s more to the story…

This single crystal structure analysis also confirmed that the mineral named marshalsussmanite is identical to the mineral schizolite, described from Greenland in 1901 and unnecessarily dropped from the valid minerals list in 1955. There was no official discreditation at the time, because this predated the establishment of IMA. Now, owing to the priority of schizolite, marshallsussmanite has been discredited and the mineral is schizolite.

So where does this leave Mont St-Hilaire serandites? Well, there is no simple answer. It seems that so far, the 1981 Ernie Schlicter-find specimens tested are all schizolite. Initially, it had been thought that perhaps the thin, bladed habit might be reliable as a diagnositc indicator, but this has proven to be too simple and unreliable a conclusion. Ongoing study of specimens is being conducted by Tony Steede at the Royal Ontario Museum lab, and he has found crystals in the thin, bladed habit that are in fact serandite. It seems that the only way to know is to have every specimen fully analyzed. Further discussion of the schizolite story and findings are expected in an upcoming article by Peter Tarassoff in Rocks and Minerals magazine, and also in the highly-anticipated upcoming new book on Mont St-Hilaire (more on that below).

This is a confirmed schizolite:

Saturday Afternoon

Saturday afternoon, we began with “Mineral Collection Matters”, by William Severance. Bill has shared specimens from his collection with us in the display room at the Symposium each year for as long as I can remember! He gave a great talk about mineral collecting, illustrated with specimens from his collection. One of my favourite aspects of mineral collecting is visiting mineral friends and going through their collection together, hearing the stories behind each piece. Bill’s talk was very much like that, with provenance of the specimens and other background, lots of collecting wisdom gleaned over the years, and some fun stories. I’ll share the one that was my favourite laugh (and I was certainly not alone):

Bill was visiting with highly-accomplished Tucson collector Jim Blees, and they had been spending time going through Jim’s collection. Bill recalled what Jim said (and we can give a small tip of the cap to Apocalypse Now):

“A great mineral specimen always comes up at the worst possible time. The house needs a new roof. Your wife needs a new washing machine. Your daughter needs braces. At that moment, you’re either a collector or you’re not. Sell the house! Sell the wife! Sell the kid! Buy the rock!“

This talk was a treat visually as well, featuring many of Jeff Scovil’s photos featured in Bill’s chapter in the Mineralogical Record Supplement, Mineral Collections of the American Northeast. (Jul/Aug 2016).

To close out our Saturday afternoon, Les Presmyk took the podium. Les has been a generous contributor in many capacities throughout Mineral World, and we were thrilled to have him back in Rochester. For those of you who might not know (or know of) Les, he has a superb collection of Arizona minerals, and has given presentations on a variety of Arizona mineral subjects. On Saturday he gave a talk he had just finished putting together, “Arizona Sulfates”.

I was intrigued by this talk as a subject matter, because when one thinks of Arizona, one does not usually jump to thinking of sulfates. Turns out there are lots of great sulfate minerals in Arizona! Far more species than only he ones that came to mind for me. Here’s just a glimpse (these are classics…):

Sunday Morning

Sunday we capped off the 46th RMS with two more excellent talks.

Chris Stefano opened with his talk, “Lucius Lee Hubbard: One of the Copper Country’s Greatest Mineral Collectors”. Hubbard was a true Renaissance man, and he was passionate about minerals. Chris told Hubbard’s story with far more than mineral specimens – he included historic photographs and Hubbard’s original correspondence, working with Hubbard’s descendants. The Hubbard collection ultimately contained many exceptional specimens, including superb Michigan copper country specimens, and it was one of the three private collections that formed the foundation for the collection of the A.E. Seaman Mineral Museum of Michigan Technological University.

And for our grand finale, Les Presmyk presented “Collecting Arizona Minerals: 150 Years of Mining, 100 Years of Statehood, and My 50-Year Journey.” This talk was awesome, featuring historical photos and packed with photos of killer specimens.

New Books!

Just a quick mention of three new books that are coming soon and were talked about a lot at the RMS – they are of particular interest to many of the people who attend RMS (and of course many more throughout Mineral World). I can’t wait for my copies of all three! Links for all of these are in the links section at the end of this blog post.

First, the project from George Robinson, Jeff Chiarenzelli and Michael Bainbridge, Minerals of the Grenville Province: New York, Ontario and Quebec should be out literally any day now (it can be ordered through Schiffer Books and will be on amazon… OR… if you will be at the Bancroft Gemboree this year (August 1-4, 2019), there will be a launch and signing, at the Bainbridge Photography booth (#145), and George Robinson will be there for a signing on Saturday, August 3, from 1:00-4:00 pm).


The new book on Mont St-Hilaire is almost here too! Mont Saint-Hilaire: History, Geology, Mineralogy by Lázló Horváth, Robert A Gault, Elsa Pfenninger-Horváth and Glenn Poirier (ed. R.F. Martin) will be released in September 2019.


And the third is the highly-anticipated book about Bill Pinch and his collection: The Pinch Collection at the Canadiane Museum of Nature, by Michael Bainbridge (eds. Gloria Staebler and Tom Wilson). It will be published in fall 2019 and the link for pre-orders is in the link section below. Bill was very involved with the preparation of this book, and the collection described has been regarded by many as perhaps the finest private collection ever assembled. With photography by Michael Bainbridge, this will be an amazing work.


Every RMS, we have great displays in the Exhibit Room and this year was no exception. Some are contributed by museums and many are contributed by collectors attending the RMS.

I say that it was no exception, but it _was_ exceptional in one respect. We have now retrofitted all of the RMS display cases with super new LED lighting. Thanks to Brian McGrath for doing all of the hard work on this – they looked awesome! (A side note, if you are interested in lighting for your own display cases, these are from Graham Sutton, with contact information in the links section below).

Here are a few glimpses from among the many great displays.

Terry Huizing assembled a case of beautiful calcite specimens in support of his talk. Some great eye-candy here!


John Betts’s display, “Recent Additions”, included many sweet specimens.


I could have chosen many for a closeup, but I chose this gorgeous chalcocite:

The Mineralogical & Geological Museum at Harvard University brought a display of great calcite specimens:


Scale: specimen on the right approx. 4 cm.

Canadian collector George Thompson brought a case, “Canadian Quartz”, with many distinctive specimens from localities that are less commonly seen:


Don Dallaire had many excellent specimens in his case dedicated to the Minerals of New Hampshire – I thought this was truly exceptional quality for cordierite:


Cordierite, Richmond Soapstone Quarry, Richmond, New Hampshire – approx. 5 cm

Bob Morgan’s case was dedicated to Epitaxy – here’s a great albite on orthoclase specimen:


Scale: approx. 10 cm tall

Carl Francis brought a case of killer quartz specimens from Switzerland:


A couple of close-up photographs from Carl’s case – these are wonderful crystals:


Quartz gwindel, Fedenstock, Uri, Switzerland – approx. 9 cm


Quartz, Rhone Glacier, Wallis, Switzerland – approx. 25 cm


As I write every year in my RMS posts, a lot of the best of Rochester occurs beyond the talks – in the halls, over meals, and on the 4th floor (the dealer floor, open when talks are not on). Socializing continues well into the morning hours each night, and includes a few traditions – among others, the not-to-be-missed Saturday night mineral songs with David Joyce. (I assume most have heard Dave’s mineral collecting and mining tunes, but if not, I’m including a link below). Somehow, I had so much fun that I forgot to be taking pictures to include here. Oops.

We have a lot of fun together at Rochester – and if you’ve never been, I hope you’ll come next year and be a part of it with us!

RMS 2020

We have another great lineup of speakers shaping up – the dates are April 23-26, 2020. Our 2020 speakers will include Calvin Anderson, John Betts, David Joyce, Vladimir Klipov, Inna Lykova, Harold Moritz, Herwig Pelckmans, Tony Potucek, Jeff Scovil and Terry Wallace.

RMS on Facebook

The Rochester Mineralogical Symposium is now on Facebook (here) (thank you Michael Bainbridge!). Our Facebook page is one good way to keep up with us – feel free to visit and give it a Like!

Until Next Year…

The Rochester Symposium is a great event, that has seen many of Mineral World’s most prominent names as contributors. At the same time, the Symposium continues to embrace contributions from all levels in mineral collecting – it simply would not be what it is without everyone who contributes.

Thank you to all of our amazing speakers this year! And thanks to our speakers and photographers for all of your help with photos to share through this report.

Of course, the Symposium could literally not happen without the dedicated efforts of the team who put it together – particularly Carl Miller, our registrar. Carl is The Man. Sarah Hanson does it all to put together the technical session and coordinate the abstracts. Tom White is our technical coordinator, insuring that all the presentations and recordings run without a hitch. Many thanks to all on our committee and those helping in the background year-round, including John Betts, Steve Chamberlain, Dan Imel, Betty Fetter, Carl Francis, Bruce Gaber, Brian McGrath, Bob Morgan, Susan Robinson, and Quintin Wight. Thanks to Paul Dudley for technical and website support. We also have a host of people helping us at the RMS and behind the scenes, including Mike Avery, Michael Bainbridge, John Diaz, Charlene Freundlich, Fred Haynes, Mark Jacobson, Jim Nizamoff, Ed Smith, Laurie Steele Sperber, Dan Sperber, Gloria Staebler, Lee Tutt, and Ken Wolf I sure hope I haven’t missed anyone!

I’ve posted great new fluorites in this Madagascar Fluorite Update (click here).

Discovered in 2017, this Madagascar green fluorite is from Mandrosonoro, Ambatofinandrahana, Amoron’i Mania. The green varies in darkness from specimen to specimen, and the hue is reminiscent of the specimens produced at the Rogerley Mine (Frosterley, Durham, England).

The apparent colour of these fluorite specimens varies depending upon light source – these photos are adjusted to basic daylight, shade (same as all specimen photos on the website), and this is the lighting that brings out their colour the best. However, in actual daylight, these fluorites exhibit varying degrees of fluorescence, from faint to obvious blue (not at all as strongly as with Rogerley fluorites). Under UV lighting, they fluoresce bright blue-purple.

The Mandrosonoro fluorites are collected by local inhabitants and the quality of the first pieces I saw (in 2018) was very poor. On the whole, the quality of almost all pieces available to date has remained poor with lots of damage – the specimens in this update are of exceptional quality for the find.

It’s hard to believe that another Tucson has come and gone already. In the middle of a cold Bancroft winter, Tucson’s wonderful warm sunshine was sure welcome.

Santa Rita Foothills, Arizona Santa Rita Foothills, southeast of Tucson

I was very fortunate to be able to experience Tucson’s natural surroundings this year. I stayed with my good friend and collecting partner David Joyce (David K. Joyce Minerals), with Carol Teal and their dog Riley at their new place in the beautiful Santa Rita Foothills, southeast of the city.

The Sonora Desert is a remarkable place in the world. In places, and at many times of year, it appears harsh and unforgiving. As to flora and fauna, the Sonora Desert gives the superficial impression that it is inhabited only by the hardiest very few species.

Saguaro SceneSaguaro Cacti

Immerse yourself in it a little, and the truth reveals itself – the variety of plants and animals is amazing (600 plant species and 200 animal species).  As with everything in life, the more quiet observation you do, the more you see. The foothills and desert areas around Tucson are full of life.

The Minerals

OK OK. I know, we all really want to read about minerals. Of course, what Tucson means is the fun of midwinter urban field collecting, and there were lots of great specimens this year.

Some beautiful and interesting specimens have continued to come from Pakistan and Afghanistan. From Pakistan, the recent brucite specimens are super – some of the finest brucite I’ve ever seen. The Killah Saifullah brucite were first noted to me by John White after he saw a couple in Munich, 2016, and since then, the quality of the finest has greatly increased over those early days. It seems that most of these are occurring in very tight seams, or with a fragmented or brecciated matrix, and so most have contacts and grey spots around them. The colour of most of them is a cream-to-very-pale-yellow, but the best have a bright yellow hue. Many are very finely crystallized, but on some, like these ones, one can easily see many crystal faces. These Pakistan brucites are amazing for the mineral.

I’ve done my best to colour-balance them accurately (daylight, shade). I always do that anyway, of course, but some mineral specimens are susceptible to really skewing away from daylight appearance when photographed.

From Afghanistan, a small number of excellent specimens have continued to come from some of the best-known occurrences, and I just want to highlight one in particular. From Sar-e Sang, Dudley Blauwet has recently brought out a couple of particularly excellent diopside specimens, and I am including one here. Given that diopside is not an uncommon mineral, it’s surprising that great matrix specimens are so hard to find. This one is striking.

Diopside, Ladujar Medam, Sar-e Sang River, Kokcha Valley, Badakhshan, Afghanistan – 8 cm

Moving on to South America, there have been a couple of particularly interesting new finds. In Potosí, Bolivia, there has been a discovery of very pretty amethyst crystals. There isn’t more specific information about the locality at this time – I’m told that this is because it is in an unnamed area of Potosi, not near to any named settlement or geographic feature. The specimens were discovered by farmers, at the edge of a field area, bordering hills. These have somewhat similar habit and appearance to some of the amethyst crystals from Peidra Parada (Las Vigas), Mexico. They are sharp, with top lustre and excellent transparency. Some are doubly-terminated, and some show a great reverse-sceptre habit. These are really sweet – I only found them available from one person, and I acquired the nicest for the website.

In Peru, there has been a new discovery of clinozoizite. I understand that the workings from which these were produced are only operational on a sporadic basis. The specific zone from which these specimens were recovered is apparently now done, and they have encountered a bit of epidote as the work has advanced. Excellent display specimens of clinozoisite are generally uncommon – one thinks of the famous finds at Alchuri in the Shigar Valley in Pakistan, and few other localities come to mind. These clinozoisite specimens are all clustered groups of crystals. I have seen no single isolated crystals. The crystals themselves are very sharp and well-defined, lustrous, with some twinned and some not.

I want to highlight one other great find that is relatively recent – the spectacular iron-cross twins of pyrite from Gachalá, Cundinamarca, Colombia, discovered about a year ago (I believe the ones available in Tucson were from the original find, as opposed to new production). The term “iron-cross twin” refers to twinned pentagonal dodecahedra, the edges of which cross at right angles. Well-defined iron-cross pyrite twins have always been uncommon and sought-after. Most are small, and often incomplete. These are quite large for iron-cross twins – they are pretty spectacular. One note about these: they have been mislabeled as goethite or limonite after pyrite. They are not pseudomorphs. In fact, they are pyrite, with a very thin surface layer of goethite.

Over to Africa, some great specimens. In Tanzania, the Merelani occurrences continue to produce very fine specimens of a number of minerals, while a few specimens from finds in recent years have surfaced as well.

From Malawi, there have been more first class specimens available from the the occurrences at Mt. Malosa and Mulanje, including arfvedsonite, eudidymite and zircon.

Over the years, the very well-known almandine occurrence at Vrondolo, Madagascar, has produced some unusually fine crystals. This occurrence is a fair distance up a small mountain – it takes hours to reach it on foot. Most often, the crystals from here are slightly to heavily chipped when extracted, because they are found frozen in solid rock. However, I found a small recent group of specimens including crystals that grew into open spaces, as well as other crystals extracted in super condition. These are really nice garnets!

Almandine, Vorondolo, Antananarivo, Madagascar

Last from Africa, Morocco continues to produce excellent specimens of many minerals – the golden age of Moroccan minerals continues. Because these finds have been known generally or written up by others, I won’t dwell too much on them in this report – there will be many fine Moroccan specimens coming on the website over the next few months. However, I want to highlight some Imilchil material that I think is noteworthy. For some time, we have seen small dark garnet crystals from Imilchil. Some of these crystals have been found to be the titanium-rich garnet group member, schorlomite, while I’m told most analyzed specimens are actually titanium-rich andradite, not enough titanium to be schorlomite. A new find at Anemzi (the same Imilchil-area locality that produces the fine green fluorapatite crystals, and has produced nice magnetites) has produced some of the nicest of these dark andradite crystals I have seen from Imilchil. At their finest, the crystals are sharp with beautiful morphology, and a good number of the specimens are comprised of a stack of these crystals. Some specimens have small, sharp, octahedral magnetite crystals in association – they are sparse, but a neat pairing. Independent from the andradites, Anemzi has produced some sharp magnetites lately as well, making for very nice specimens.

My final mineral entry is from China. I feel that the find of fluorite from Fujian deserves a mention, even though China has produced so much fluorite over the years. These new ones are the fluorites that have been dubbed “tanzanite fluorite” by several dealers. These have been available since early 2017, and they were not widespread this year at Tucson. The ones available were quite expensive. This locality has produced a range of fluorite – the most tanzanite blue-purple is from the one 2017 find, while other blues and purple hues have been recovered as well. I’ve been told there is “no more” – of course!!! – and we’ve all heard that so many times before, so skepticism is certainly warranted! I personally will believe it when I see it. However, I didn’t see as much as I expected and hoped, so we’ll see. Moreover, most of the specimens I did see were significantly contacted and/or damaged. I believe this is not only reflecting the way they were collected (perhaps in some cases with less care than we’d like), but also due to the nature of the occurrence. Many of these seem to have formed in very tight and narrow spaces, and would have been exceptionally difficult to extract without any contacting issues. I think the overall story of this locality will be clearer over time. Given that there are several colour hues and crystal habits from this locality, so it seems likely there was more than one pocket. These are beautiful fluorite specimens!

A Remarkable Emerald

My friend John White came upon a remarkable emerald specimen from Pakistan and I want to share a photo. I’ve never seen anything like it, and much more important, John (you likely know, the former curator of the Smithsonian Institution’s mineral collection) has never seen anything like it! It is available.

First shipping run to Bancroft.
Dad, I’ll drive.

In only a couple of months he has transformed from tiny puppy to young dog. He’s gleeful about pretty much everything.

Rudy McDougallSnow? Love it!

Rudy is of course new to all this mineral business. Our founding Labrador Retriever, Emery, supervised all operations – he was the Chairman of the Afternoon Snooze Committee and comprised our IT Department, although he slept through most of our business operations. It will be a while until Rudy is ready to step into Emery’s higher roles, but he is a great little supervisor. For now, he is happy to be a particularly active part of all packing, shipping and particularly unpacking operations. He has delighted in founding our Playful Mayhem Department.

What do you mean, my office chair is for “sleeping” while you work?

With lots of Tucson minerals to come, Rudy and I will do our best to get them online over the next few weeks!

This Magnesiofoitite Tourmaline Update features crystals of magnesiofoitite that are simply amazing for the species. These crystals are from a large collapsed pocket in Tsitondroina Commune, in the Ikalamavony District, Matsiatra Region, Fianarantsoa Province, Madagascar. Sharp and lustrous, with somewhat varied crystal habits, these crystals comprise a remarkable find.

After a long, harsh northern winter, most people in this part of the world look to the arrival of the red-winged blackbirds and robins, buds and flowers to mark the arrival of spring. But let’s be honest, spring only truly arrives with “Rochester” (the annual Rochester Mineralogical Symposium). For fun, sense of community, contribution and cameraderie – and for the excellence of the presentations and displays – this is by far one of the best mineral events of the year, anywhere.  (And speaking of contribution, please note that the speakers were all generous in sharing their photographs for this post – thank you all!)  Organized by Steve and Helen Chamberlain, along with a team of dedicated volunteers, it is not to be missed.

Just a word about it, if you’ve never been: Come!

Rochester is a symposium meant for people who love minerals. It is not purely academic or technical – it is rich in substantive content, with cutting edge discoveries and research in specimen mineralogy, yet accessible to people at all levels of expertise.  The overall content is a super mix of mineralogy, photography, historical content, research, collecting information and glimpses of amazing places and people around the world.

The symposium (April 24-27) was incredibly high calibre, with excellent presentations by speakers from many different countries.  In case you were not there – or even if you were – I hope you will enjoy reading about it and looking at a few of the photos. All of the speakers have kindly contributed photographs from their talks.


Michael Bainbridge’s “Grenville Grunge? Dispelling the Myth!” launched the symposium but lived on through the weekend. “Grenville Grunge” refers to the fact that some minerals found in the Grenville Geological Province, including parts of Ontario, Quebec and New York, can be dull, dark, and lacking sharpness, lustre or colour. It is a disparaging name coined by someone hopelessly misguided and misinformed. But I digress.

You may know Michael is an excellent mineral photographer, and so his presentation photos helped put an aesthetic face on Grenville Province minerals. However, the catchy alliteration “Grenville Grunge” seems to know no bounds. In a baffling development, it was repeated derisively by people around the symposium all weekend, and so the phrase lives on. It might even inadvertently have been granted a bit of new life… but don’t go propagating it. You can easily find shapeless lumps of mineralogical ugliness at awesome localities the world over. (It’s truly a ridiculous moniker – I will make it a mission of this website over time to help you see whether you agree. Because in fact, the sophistication, complexity and cool subtleties of Grenville minerals can be downright addictive.)

Michael collected this specimen in 2010.

John Jaszczak gave a fantastic presentation “Mineralogical Miracles at Merelani”, about some of the interesting mineral finds at Merelani, Tanzania beyond tanzanite and tsavorite. John spoke about the amazing crystals of graphite and diopside, and also about the recent finds of killer alabandite and wurtzite crystals. A Mineralogical Record article about the latter is in the works – can’t wait for it.

A super talk about one of the world’s most classic localities, the famous Herodsfoot Mine, was presented by Roy Starkey (“Herodsfoot Mine, Richard Talling and Bournonite”). Meticulously researched, with excellent mix of historical background and great minerals, and supported with lots of great photographs.

One of my favourite subjects of the symposium was the Sulfur Mines of Sicily, featured in the Friday night presentation by Dr. Renato Pagano.

I have a confession here (mineral connoisseurs might say a huge confession). And I guess it’s a bit embarrassing, since I swear I really thought I had read Dr. Pagano’s (and other authors’) writings on this. But somehow it was only now that I finally have come to understand that Sicilian sulfur deposits are not volcanic deposits – it’s just so natural to assume that the famous active volcanoes on Sicily gave rise to and host the famous sulfur deposits, but this is not the case. Sulfur in Sicily occurs in a sequence of Miocene evaporitic formations including limestone and gypsum.

Anyway, now that my admission is out of the way…

Dr. Pagano included wonderful photographs and shared some amazing specimens with us – he provided a couple of my favourites for this post. The following are two specimens from the Pagano collection, photographed by Roberto Appiani.


Slide4And I love the photos from some time ago now, when Dr. Pagano was making early trips to the region to obtain sulfur specimens – and then stacking them on the back of his bike.


One of the best things about Rochester is that every year we end up in so many different mineral places, near and far. Over the years, Dr. Peter Lyckberg has made many visits to the Chamber Pegmatites of Volodarsk, Ukraine, and gave just an amazing talk on this – really, this presentation was so good you felt like you were right there, underground, collecting beryl and topaz. The mining of the chamber pegmatites has an interesting history, including massive state-sponsored investment during the Soviet era, without which, none of this could have been possible. However, it is a story that may be at an end, as the last mining has stopped as of January, 2013.  Peter clearly sensed that the chances to visit Volodarsk could be time-limited, and we’re so lucky he did!

Peter brought this beautiful topaz to show us at the Symposium – I’m guessing almost 15 cm across.
(The “matrix” in this photo is the dry-cleaning plastic we all use for packing specimens.)

Mark Jacobson took us to Mount Antero, Colorado, the classic Western American aquamarine locality. To me, the approach taken in presenting this really made it – the talk highlighted many of the collectors themselves, and their finds over the years. This was a great approach and a very engaging talk. The presentation included lots of photos of specimens of the “big three” from Mt. Antero – beryl (variety aquamarine), phenakite and bertrandite.

Ted Johnson spoke on the pegmatite occurrence at Branchville, Connecticut. This is a locality for some very unusual minerals and interesting mineralogy/genesis. Unfortunately the locality is closed to collecting – a house is very nearby, and a road runs very close to the water-filled pit. However, analytical work by dedicated amateurs continues, and this is a great example of such contributions being made to specimen mineralogy.

Often, we are lucky enough to have key speakers give us a reprise on a separate subject to close out the symposium on Sunday morning.

Roy Starkey presented on the Cairngorm mountain range in Scotland. If you have read any older field guide, monograph or text, you have likely seen that the Cairngorms are a classic locality for smoky quartz crystals – so much so that they were sometimes themselves called cairngorms.  There was lots of great information in this talk – I had no idea that excellent topaz has also been found in the Cairngorms.  I also had no clue that Queen Victoria had done any field collecting for minerals…

Dr. Peter Lyckberg gave us our grande finale, with “Highlights of 50 Years of Mineral Collecting”. The personal nature of this talk really resonated with me. He began his fascination and collecting of minerals when he was very young, and he has pursued it passionately ever since – many of us could truly relate. With a whirlwind tour, we visited localities worldwide, and had a chance to see some truly spectacular mineral specimens that have become part of his great personal collection – often after some rather dedicated pursuit!

Technical Session

Every year, Friday afternoon of the symposium is reserved for the technical session. This session is  always packed with tons of information – each presenter is limited to 15 minutes. Abstracts from these talks are included in the symposium program, and are also published during the year in Rocks and Minerals magazine.

Annual Features

The symposium includes some consistent high-level features every year.

Saturday morning always features Jeff Scovil presenting What’s New in Minerals and Localities. Jeff’s world-leading mineral photography dazzles us all for an hour, as he covers finds from around the globe that were uncovered in the prior year or so. Some of these are photographs that we see in the Mineralogical Record, Rocks and Minerals, and other publications during the year and other photographs may make their debut at Rochester – and when they are all together in one show, it’s a bit mind boggling.  I’ve never once seen Jeff do What’s New without having the audience draw breath collectively over some of the specimens.  (People might even pass out over the experience – I mean it’s always dark during the slideshow, so how would we know – although miraculously no-one is on the floor at the end.)

Following Jeff, “What’s New in Minerals and Localities II” is the chance for short contributions from other symposium registrants – we never have any idea what will come out during this hour, but always new, and one of the neatest sessions of the Symposium, where we can share with each other.

Frank Melanson spoke about the new Bancroft Gem and Mineral Club Museum – I will post a separate piece on the blog about this one, coming soon, so stay tuned.

I presented briefly on some recent new mineral finds, including the amazing magnesiofoititite tourmaline crystals from Tsitondroina, Fianarantsoa, Madagascar.

CoverMagnesiofoitite, Tsitondroina, Fianarantsoa, Madagascar – 5.8 cm.

 I also presented on a remarkable Canadian find. One of Canada’s top field collectors, Mike Irwin, has discovered and collected some very fine specimens of the rare mineral serendibite from near Portage du Fort, Pontiac Co., Quebec.  Many of the specimens include some level of overgrowth and/or replacement growth by a combination of dravite-uvite and spinel. In some of the material, the serendibite is a nice blue, mottled in a lighter host rock which includes very pale diopside. The blue is an understated, blue-jean blue (suits us Canadians) rather than an outspoken copper oxide zone blue. So far, extremely few euhedral crystals have been recovered – vugs are rare at the locality.


Sharp serendibite crystals, up to 0.5 cm, with pale diopside – near Portage-du-Fort, Pontiac Co., Quebec.

R. Peter Richards has presented many fascinating topics to us at Rochester over the years. This one was to follow up on a remarkable find.  There is a locality along the Huron River, near Milan, Ohio, discovered thanks to smoke rising up out of a crevice. The smoke, from a natural shale fire underground, deposited micro-crystals, which at the time of the original presentation had not yet been identified. Subsequent work has now confirmed that these are sabieite-2H and -3R, intimately mixed in single crystals.  They are new polytypes of sabieite 1-T.  Unfortunately the material was incredibly limited and no specimens are available.

Finally, Gloria Staebler (of Lithographie LLC) spoke about what I think is a great development for the hobby: Lithographie is going to be publishing a new edition of the classic, Mineralogy for Amateurs by John Sinkankas, originally published in 1964.  (If you’ve read my Favourite Mineral Reads post, you’ll know this is one of my favourite mineral books of all time.) The new edition is undergoing significant work, in order to update the information, although it is fundamental to the project that the voice, tone and approach remain true to the Sinkankas original.  The new edition will be published as a two-volume set, with major revisions to update the mineral descriptions.  Gloria has many people involved, and is keen to involve more.  For example, she is planning to have given minerals updated by a single experienced individual (one person will do hematite, another will do pyrite and so on).  There is lots to be done, and if you would like to contribute to the revision of this classic, please contact Gloria and let her know of your interest at .


As always, there were some great displays this year, both from museums and private collections.


Super display of Nova Scotia Minerals by Canadian collector George Thompson.


 John Betts had a great display of U.S. minerals, including this great smoky quartz (ca 12 cm) he collected in 1992.


Excellent display of pseudomorphs (specifically, these are perimorphs, which are formed when one mineral is encrusted by a second mineral, and the second mineral (crust) still remains while the original mineral has dissolved, leaving a hollow interior). Cincinnati Museum Centre display of specimens on loan from the Terry Huizing Collection.


Remarkable brucite specimen, ca. 15 cm across, from Texas, Lancaster Co., Pennsylvania.  Formerly in the  famous William Jeffris Collection, then acquired by Andrew Carnegie in 1904.  Now in the A.E. Seaman Mineral Museum collection.


Wonderful copper specimen in the collection of David K. Joyce – about 7 cm tall – it stands up straight like this and has been referred to as the “Copper Man”.

Dealers’ Rooms

As great as the presentations, program and displays are, a lot of what Rochester is about happens up on the famous fourth floor, where the dealers’ rooms are full of life well into the morning hours.


David K. Joyce plays and sings his mineral and mining songs every year at Rochester – it’s always a highlight, hanging out with friends and singing along.
(In this photo Dave is between songs, while Canadian dealer and collector Jonathan Zvonko looks on.)

If you have not yet heard Dave’s tunes, they are available on CD and downloadable from iTunes – and you can check them out here.

In another fun fourth floor moment, to the amusement and laughter of all in the room, John Betts made a presentation to me, welcoming me as a new internet mineral dealer. He presented me with an Internet Mineral Dealer’s Kit, to help me on my way.  Some of the contents of that kit simply can’t be discussed here. Suffice it to say that it included screws, mineral oil, Preparation H, a candle, a guide to ordering beer in 26 different languages… and other helpful items. The egg timer in the kit is meant to speed up my photography (a particularly good laugh).  And John feels strongly that I am not writing enough in bold all-caps (particularly the word RARE), and I’m using far too few exclamation marks.


John Betts presenting me with a printed sheet full of exclamation marks and multiple examples of the word “RARE!!!” to give me an idea
of what a mineral dealing website should really look like. David K. Joyce photo.

John has been one of the leading online mineral dealers since the beginning of the internet age – if you have not been to his website, it is truly one of the best. I mean BEST EVER!!! and MOST COMPREHENSIVELY AWESOME!!!!  SUPER RARE!!!

Rochester is all about good times with good friends in mineral world.

Until Next Year…

It is true for most Rochester fans – once you have been, you really do your best to never miss another one.  So if you haven’t been, come and experience one of the best events of the mineral year with those of us who wouldn’t miss it (April 23-April 26, 2015). And of course to all the Rochester friends who are there each year, thanks for the great time together and see you there next year.

Urban Field Collecting

Each year when “Tucson” nears, I’m like a kid who can’t wait to race downstairs on Christmas morning. Just the chance to experience the sprawling mineral shows all over the city (known collectively in Mineral World simply as “Tucson”)… there is so much to see and we all come away with different impressions.

This is just a brief blog post about a few favourite finds from Tucson 2014 that you might find interesting. I’m also including a few words below about Bisbee and the great little museum there, but not before Tucson (!).

I have been travelling to Tucson with my collecting partner David Joyce every year for a long time now. Finding what we’re after can be tough! We embark on excursions involving long trekking, backpacks, headlamps, loupes… sledge hammers and drills… Ok, ok, no sledges and drills. But it’s still urban field collecting. We work through a lot of rock in hopes of finding something great – and eventually we do.

The Music

Before I get to mineral specimens, I’ll start with something that was entirely new to Mineral World. Dave premiered his new CD – Nuggets and High Grade: The Mining and Mineral Collecting Songs of David K. Joyce. So, it was no ordinary Tucson. The guitar, the fans, the autographs, the crowd control barriers, the police escorts… (or something like that, anyway…)

Dave played small gigs around Tucson, including a great evening of Krupnik and Kielbasa hosted of course by Spirifer Minerals, and wine and cheese hosted by Dave Bunk Minerals up at the Westward Look show.


The songs and instrumentals were played around the show, including at the Main Show – and they could be heard on sound systems coming from dealers’ rooms as you walked by. Light-hearted with good laughs, these are songs for mineral collectors. (If you haven’t heard Damn The Glaciers or The Mineral Dealer, you haven’t lived.) I feel safe predicting that many of these songs will be played live during the Rochester Mineralogical Symposium, if you’d like to sing along in person. In the meantime, they are available on CD and downloadable from iTunes. If you have not yet heard these tunes, check them out here.

The Minerals

Moving on from the Rock Star to the rocks themselves… here are a few of the mineral finds I thought were special. (Some are new, and some are minerals that have debuted before now, where the prices, quality, or quantity have really improved.) Specimens from all of these finds will be available on our website in the coming weeks.

China remains at the forefront for new and interesting mineral specimens.

There are amazing new calcite specimens from Chenzhou Prefecture, Hunan Province, China (specifics on locality were not freely forthcoming as yet – if you know more I’d love to hear from you (email or here). These are comprised of first generation scalenohedral crystals capped by second generation flattened calcite crystals, giving wonderful aesthetic form, including even an almost mushroom-like appearance. Unfortunately most that I saw from this find were damaged, but I managed to find a few that were in super shape. These are very cool specimens!

Calcite, China

Another interesting new one was a find of beautifully twinned cerussite at the famous Daoping Mine, Gongcheng Co., Guilin Prefecture, Guangxi Zhuang Autonomous Region, China, which is most famous for pyromorphite. Although nice specimens of blocky yellow cerussite crystals were found a few years ago at the locality, these ones are distinctly different – they are flattened, twinned and nicely coloured. I only acquired one (photographed below), because for the most part prices were high for what they are, and I saw only a very few that were high enough quality. Nonetheless there may be a few others around so keep your eyes open for them. I only saw them with the one dealer in Tucson – who knows if there could be more?


Cerussite from the Daoping Mine, Gongcheng Co., Guilin Prefecture, Guangxi Zhuang Autonomous Region, China – 3.1 cm

The latest specimens of chalcopyrite on siderite from Kaiwu, Hezhang County, Ghizou Province, China, are higher quality than most that have been coming out in the past, with sharp chalcopyrites and a new twist on a couple, which include tennantite (confirmed by post-Tucson analysis). When these were first coming out, so many were badly damaged, and even so, they were incredibly expensive.


Chalcopyrite and Siderite from Kaiwu, Hezhang County, Ghizou Province, China – 9.6 cm

The Huangguang mines in Inner Mongolia have continued to produce some wonderful mineral specimens. Many prices asked are still beyond the reach of mere mortals… but with some serious searching, fine specimens of several minerals were obtainable, including sharp ilvaites, some lollingites (most are still pricey) and others. What a great contemporary mineral producing region!

Moving on to the other world famous deposit with some strikingly similar mineralogy to the Huangguang Mines, some fine specimens continue to come from Dalnegorsk, Russia. In particular, there were some nice fluorite crystals. There were also really neat quartz crystals with overgrowths of beta quartz, and also a few tabular-style pyrrhotites.

Coming further west, the famed type locality for dioptase at Altyn-Tyube in the Kirghiz Steppes, Karagandy Province, Kazakhstan is producing some beautiful specimens and operations continue, with hopes of more in the future. A couple of gorgeous ones are here.

A truly new find was the pocket of wonderful black tourmalines found at Tsitondroina, Fianarantsoa, Madagascar – they are magnesiofoitite. The crystallography on these is pretty amazing. I acquired the best of them and they will be posted on the site soon.

And the last one for now – some really great datolite crystals have recently been found at Charcas, Mun de Charcas, San Luis Potosí, Mexico. The datolite crystals can reach several centimetres across and range from pale green to pale blue. Some of the datolite crystals show a preferential crystallization habit, with highlighted white faces representing certain crystal forms. A number of the datolite specimens are accompanied by sulfide mineralization – primarily pyrite and chalcopyrite, crystals of which even occur fully included within datolite crystals.

Where Minerals Go to Die

Just as an aside, have you ever wondered where minerals go to die? During real field collecting, the answer is usually the mine dumps. But what happens in the context of urban field collecting?

There are places in Tucson where mineral specimens are thrown on top of each other, piled, crunched, maybe bathed in oil, bleached under the intense Arizona sun…


Imagine a fine mineral specimen surviving this mayhem (not sure why we need the pretext of boxes here)

Urban Field Collecting Can Wipe a Guy Out

(Dave likes to call it “power-napping.” Possibly because it sounds more productive than “snoozing on the grass.”)

World Famous Bisbee

Although I could look at minerals all day every day an never tire of it, there’s something attractive to a change of pace and scenery, so we headed to Bisbee. The trip to Bisbee leads through Tombstone, famous in its own right as one of the roughest towns of the American Old West, best known for the gunfight at the O.K. Corral. Many of the lives of the early inhabitants of Tombstone ended prematurely.

(Interesting about the name “Boot Hill”: This name was commonly given to cemeteries in the American Old West and was derived from the notion that this was where the gunfighters – the people who died with their boots on – were buried. The Cemetery at Boot Hill, Tombstone was not limited to gunfighters.)

If you’ve never done the day-trip from Tucson to Bisbee, it’s worth it.


Headframe at Bisbee

Of course Bisbee is best known among mineral collectors for its historic copper mines, which are among the United States’ most prolific mineral specimen localities (325 different minerals have been found at Bisbee). The old mining operations feature prominently on the modern landscape of the Bisbee area.

Bisbee itself is a neat town with lots of older buildings, artists’ studios and shops. But (as you might guess) the highlight of the visit for me was the Bisbee Mining and Historical Museum. This little museum is so well done! A member of the Smithsonian Institution’s Affiliation Program, the displays were designed with the Smithsonian’s assistance. They are fascinating, informative and easy to walk through for however long (or not) you might want to stay. The museum is housed in the building that was once the corporate headquarters of the Copper Queen Consolidated Mining Company (eventually purchased by Phelps Dodge Corporation, which was subsequently acquired by Freeport McMoRan Copper and Gold Inc.) – it is a beautifully preserved building and a National Registered Landmark.


The upper floor of the museum’s displays includes underground mine scenes and some mineral specimens from various collections:

Calcite on Malachite from the Copper Queen Mine – approx. 12 cm
(James Douglas Collection, Smithsonian Institution Collection)


Malachite pseudomorph after Azurite from the Holbrook Mine – approx. 15 cm
(M.J. Cunningham Collection, Bank of America)

I used to be on it for 18 years. The side effects are that it makes me sleepy.


Gorgeous Cuprite from the Czar Mine – approx. 10 cm – largest crystal perhaps 1.2 cm
(M.J. Cunningham Collection, Bank of America)

I stumbled out of the museum, as those unforgettable red cubes were making my head swim! Nice way to end the day in Bisbee.

Back in Tucson, it was time to wrap and pack specimens for shipment! We had a few last fine meals with mineral and mining friends before saying goodbye and heading back to the Great White North.
