Cylindrite (Fioravanti Coll.)

Item Description

All sides of this top of this sculptural and rich of specimen are covered with one of the most unique species in all the mineral kingdom. Cylindrite is a lead, iron, tin, antimony sulfosalt that forms in "cylinder" or "tube" shaped crystals, hence the name. The mine at Poopo is the type locality for the species. A great opportunity for any collector to own a species rarely seen for sale in today's market. Incidentally, this species belongs to the only group of minerals that forms in naturally "round" or "cylindrical" shaped crystals. I have not seen many new specimens of cylindrite on the market in several years, and the pieces from Poopo are certainly among the best in the world. Older material from the Giancarlo Fioravanti Collection, obtained in a trade with the Naples Mineral Musuem in 1978.
