I’ve posted the second 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)

I’ve added a group of diverse minerals in this Peru Update (click here). I have selected these out over various trips – each is a beautiful specimen for the mineral! This update includes a gorgeous rhodonite from Chiurucu, a brilliant alabandite, a super specimen of bournonite cogwheel twins on matrix, a specimen of scheelite coated with bright green stolzite, fluorescent fluorapatite crystals and more.

I’ve posted a new Brazil Update (click here), with superb, diverse specimens.

From the world famous morganite finds at the Urucum Mine, this crystal is likely from the 1973 pocket.

Beryl, var. Morganite, Urucum Mine,  Galileia, Minas Gerais, BrazillBeryl, var. Morganite, Urucum Mine, Galileia, Minas Gerais, Brazil – 7.9 cm

A one-of-a-kind specimen, this aqua-colours montebrasite crystal was found in a pocket in the 1970s. Most of the pocket material was etched and did not exhibit crystal faces.

Montebrasite, Lavra da Ilha, Taquaral, Itinga, Minas Gerais, BrazilMontebrasite, Lavra da Ilha, Taquaral, Itinga, Minas Gerais, Brazil – 3.9 cm

From a new recent find, a small pocket at Novo Horizonte produced a small number of remarkable crystals, sold to me under the label “synchysite”. Subsequent analysis by Don Doell has confirmed more about their identity. Having conducted semi-quantitative EDS at SGS Labs, Don found that these are in fact phosphate mineralization, and they are likely a combination of rhabdophane-(La), rhabdophane-(Ce) and possibly including monazite-(Ce). They appear to be pseudomorphs after a REE carbonate, probably in the parisite group, given that parisite-(La) has been found at Novo Horizonte in crystals with a similar aspect and appearance, at a similar time. They could also be after bastnasite-(La), which has been described from the locality. For now, I’m labelling them rhabdophane, pseudomorph after parisite, with the proviso that the above is the technically closest identification information to date. Thanks very much to Don for this analysis!

Also from Novo Horizonte, a tabular crystal of rutilated quartz, in superb condition and with bright prismatic golden rutile crystals:

From Brumado, excellent pleochroic crystals of uvite tourmaline, exhibiting purple hues at certain angles and greenish hues when viewed from other angles. The first two photographs below are views of the same uvite crystal from different viewing angles.
