About 30 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 for sale because it is just covered with small, sharp, bright, prismatic Arsenopyrite crystals plus golden Pyrite cyrstlas on matrix. The largest Arsenopyrite crystal measures 8 mm in lenght. 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.
