Franckeite (Whitmore Coll.)

Item Description

Franckeite is one of the rarest sulfosalts in the world. This artistic specimen is a very rich, incredibly rare, superb quality, crystallized example of the triclinic lead, tin, iron, antimony sulfosalt consisting of somewhat "sword"-shaped crystals oriented into very sculptural spherical aggregates. Looks great from the front or back, which is very uncommon! Ex Robert Whitmore Collection.
