Valentinite (2011 find)

Item Description

From a find in the summer of 2011, this is one of the best discoveries of Valentinite ever made at the famous San Jose mine in Bolivia. Over the last decade or so, this mine has produced the finest Andorite crystals extant, the finest known crystals of Potosiite, and some of the most impressive large twinned Stannite ever seen just to name a few of its merits. For centuries, the San Jose mine has been producing minerals (mostly Silver for the the Spanish which dates as far back as the year 1595 and was mined by Incan Indians for several centuries prior), but in the 20th Century, it yielded some of the finest crystallized Valentinites in the world. Nearly 10 years ago, the only Valentinites to come out of Bolivia were those from Colavi, but they don't stand up to the finest ones from San Jose. As of right now, we can say that this most recent discovery of Valentinite is not only noteworty, but impressive for the mine and species. This particular piece is a good example of this rare Antimony Oxide (Pronounced: Vah-LEN-tin-ite). It features a few, sharp, semi lustrous, silvery color (included with micro Galena) prismatic crystals which are associated with massive grey Galena and Quartz and Pyrite matrix. The largest crystal, which measures 1.0 cm is in good shape overall, despite a little roughness. The fact that the largest crystal is a full centimeter is great for this locality and the species. A great chance to have a matrix specimen of a very hard to find mineral from one of the most notable localities in Bolivia. Species collectors out there should jump on this one, but worldwide collectors should not pass it up either. We have precious few of these pieces to offer at the moment, but we are hoping through our contacts to have more specimens in the coming months.
