Franckeite with Zinkenite (rare material)

Item Description

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. They are associated with very rare silvery, prismatic "needles" of Zinkenite, which is a very uncommon association from any locality. A great miniature specimen for somebody looking to own a rare and highly displayable mineral specimen. It is also good opportunity to acquire something that is rarely offered in the open market for a great price. Franckeite belongs to the only group of minerals that forms in naturally "round" or "cylindrical" shaped crystals. This specimen nearly 40 years old (it was mined in the late 1970s) and was part of the best discovery of the material to date. There were only a handful of good specimens, and well crystallized display pieces like this are few and far between. Valued at $450.
