Cylindrite (rare) (ex Dr. Miguel Romero Collection)

Item Description

This is a rich of specimen of 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 loaded with crystals. The longest crystal measures 1.6 cm and they show the classic steel-grey hue with the unusual cylindrical shape. The piece also features thicker crystals than what we're typically used to seeing for this material. 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 any new specimens of Cylindrite on the market in several years, and the pieces from Poopo are certainly among the best in the world. Priced at $1250. From the collection of Senator / Dr. Miguel Romero of Teuhuacan, Mexico (Collection #1507).
