Gustavite with Lillianite (ex Matioli Collection)

Item Description

Some of the best known specimens of this rare silver lead bismuth sulfide are those from the Rotgulden area in Salzburg, Austria. This piece features silvery-grey orthorhombic Gustavite crystals in Chalcopyrite host rock matrix. The label states that Lillianite is present with the Gustavite, and the two species do form a series, it's hard to say for certain if there is truly Lillianite without chemical analysis. Gustavite was named after Gustav Adolf Hageman, a chemical engineer for the Cryolite Firm (Ivigtut, Greenland). This piece is best viewed under magnification, but it's more than just a micro piece, it's a great opportunity to pick up a VERY hard to find mineral from one of the premier localities for the species.
