I’ve added great new specimens in a new update of pieces from the Steve Szilard Collection (click here).  This update includes fine mineral specimens from all over the world.

Steve Szilard is a well-known and highly respected Canadian mineral collector who began collecting in 1982. It may strike a chord with many of you that one of his first two mineral books was the Peterson Field Guide to Rocks and Minerals by Fred Pough – that was certainly true for me too (and my own copy sure looks as well used as it has been!). Steve is a skilled and accomplished field collector, having collected extensively in Ontario, as well as in almost all Canadian provinces and across the United States. Having travelled the world acquiring minerals in many countries, he has also attended many mineral shows – in particular, he has attended the Rochester Mineralogical Symposium for almost 30 years. Steve has a long record of mineral community involvement and contribution, having been with the Walker Mineralogical Club in Toronto since 1985 (and a member of the executive for many of the years since then) – he has also been a member of the Scarborough Gem and Mineral Club, the Kawartha Rock and Fossil Club and the Canadian Micro Mineral Association. As you might expect, given his mineral collecting career, Steve is incredibly knowledgeable about minerals and many mineral-related subjects. He has always been kind and generous with his knowledge. Steve has enjoyed assisting in the activities of a great organization, the Young Toronto Mineralogists Club, including talks, using binocular microscopes, and field trips. It is my pleasure to be able to share his collection with you.

I’ve posted the first in a series of updates with superb specimens from John S. White’s collection (click here).

Most of you will likely know a bit about John, given that among his many accomplishments in the mineral world he is the founder of the Mineralogical Record, former curator of the U.S. National Mineral and Gem Collection at the Smithsonian Institution and author of two books and over 200 articles. I’ve written a short post about him with some great photos – hope you enjoy it! (click here)

These wonderful high-quality specimens from John’s collection are from a wide range of localities (classic to contemporary) and include a variety of minerals.

I’ve posted excellent new Kazakhstan dioptase specimens in the Dioptase Update – May 2016 (click here). These beautiful specimens were mined in 2015, and acquired from the team currently conducting specimen mining at Altyn Tyube soon afterward.

Dioptase was first described from Altyn Tyube, the type locality for dioptase, in the nineteenth century. Altyn Tyube is a remarkable deposit in the Steppes, far from everywhere. It was first worked for copper thousands of years B.C., and it is interesting to note that there are very few copper minerals at the locality – dioptase with occasional minor malachite and cuprite.
