SOLD Ozocerite
stock #SOLD 8.1-397
Galacia, Poland
11.6 x 4.8 x 2.8 CM (cabinet)
price: $0
Spring 2020

Simply put this is a really ugly mineral that can even have an unpleasant odor. A natural paraffin wax-like substance derived from Hydrocarbons, this looks much like a rotted banana, it is translucent and has a density less than 1 so it floats. This is an old specimen from Poland with a 1930-40 vintage Schortmann label, this piece is now almost completely odor free perhaps because of its age. However the literature tells us that heating to a moderate warm temperature or any rubbing will again produce the bad smell along with a negative electric charge. The name comes from the Greek meaning "stench wax". This is a super strange mineral that is never seen for sale (and I have never been asked for any either). This locality is not listed in Mindat but that may be due to the many changes to the names and geography of that area over the past hundred years. Certainly not a specimen for a collector of fine esthetics, but a large example of a legitimate mineral almost never seen in any collection. Weird.
Selenite with Herbertsmithite inclusions
stock #16.1-535
Rudna mine, Lubin, Legnica
Lower Silesia, Poland
8.3 x 7.8 x 7.3 CM (cabinet)
price: $1150

A well crystalized cluster of Gypsum (Selenite) with rich green inclusions and encrustations of the rare mineral Herbertsmithite. This find has produced what are certainly the most esthetic examples of this specie as Herbertsmithite is not usually a "display" grade mineral. Recently Herbersmithite was found to have unique properties of changeable magnetism and with quantum spin properties. This was picked up in some of the popular media and somewhat exaggerated as news, even being called a "new form of matter". There was a brief period where tiny crumbs were being sold for high prices. Despite the inaccurate hype this is a remarkable mineral and on this specimen it is actually attractive.
Celestite on Sulphur
stock #AX-10-1016
Machow Mine, Tarnobrzeg
Podkarpackie, Poland
9.3 x 6.6 x 4.9 CM (cabinet)
price: $330
Post Tucson 2015

Bright and gemmy Celestite (Celestine) crystals are in radial sprays on vivid Sulphur crystals. In fine condition, the matrix is an open pocket that has protected the delicate crystals inside. Similar to old specimens from Sicily, the luster and sparkle of this specimen is equal to those.
