Franckeite

Item Description

This is one of the rarest sulfosalts in the world. This specimen is a rich, incredibly rare, good quality, crystallized specimen of the triclinic lead, tin, iron, antimony sulfosalt Franckeite consisting of somewhat "sword"-shaped crystals oriented into spherical aggregates forming a nice miniature display specimen. This piece is good specimen for somebody looking to own a displayable piece of an exceptionally rare mineral. 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 35 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.
