- Small Cabinet, 6.3 x 4.7 x 3.6 cm
- Santa Cruz Mine, Poopo, Oruro Department, Bolivia
Partially embedded in massive ore are slender prisms, to 2 cm in length, of splendent, bright, metallic silver colored crystals of cylindrite, an uncommon lead, tin, antimony, iron sulfide. This piece has very robust crystals. Notably, this is the only mineral species with CYLINDRICAL crystallization! So far as I am aware, it Only comes from this one old mine. This is a particularly nice display piece, for balance and size.
