Galena with Arsenopyrite

Item Description

About 35 years ago, there were a handful of very good quality Arsenopyrite specimens on the market from the San Jose mine, but they all seemed to have dried up. This is one of the more attractive specimens of this material that I have offered in the auctions as it features fantastic, sharp, bright, prismatic Arsenopyrite which are coated by sharp, lustrous, metallic silvery colored cuboctahedra of Galena on matrix. The largest crystal measures about 2 mm across. This piece was mined in 1980 and is a great example of this old material from one of the most famous mines in the Bolivian tin belt. I know this appears to be fairly common, but it's certainly worth picking up if you collect sulfides, Bolivian minerals or well-crystallized examples of mineral species.
