Small Cabinet, 6.5 x 4.6 x 2.8 cm
San Jose Mine, Oruro City, Cercado Province, Oruro Department, Bolivia
This is one of the rarest sulfosalts in the world. This specimen is a very rich, incredibly rare, superb quality, crystallized specimen of the triclinic lead, tin, iron, antimony sulfosalt Franckeite consisting of somewhat "sword"-shaped crystals oriented into spherical aggregates forming the shape of a flower. A great small cabinet specimen for somebody looking to own a rare and highly displayable mineral specimen. A good opportunity to acquire something that is rarely offered in the open market for a great price. This species belongs to the only group of minerals that forms in naturally "round" or "cylindrical" shaped crystals. This specimen is over 30 years old and was part of the best find of the material. There were only a handful of good specimens, and well crystallized display pieces like this are few and far between. 6.5 x 4.6 x 2.8cm
