Cylindrite (rare - rich) Type Locality

Item Description

All sides of this striking 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. This specimen is especially nice considering that it is totally loaded with sprays of silvery-bright crystals. Crystals reach 4.0 cm. 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.
