Description

Two milky white aggregates of this very rare mineral of Bi, Mo and Na with a close relationship with wulfenite. Its name come from the type and unique locality, famous for its exclusive minerals of bismuth, molybdenum, thorium and REE. Only very few specimens of this extremely rare mineral are known, as far as I know, at the moment, I can tell within 10-12 specimens worldwide including the holotype. The sample has been confirmed via Raman and the analyzes will be sent with it.
This exceptional specimen in addition to the two crystalline clusters of suseinargiuite is made rarer by a wonderful bundle of pale yellow vitreous crystals of sardignaite of the best quality. Personally found 2009. Outstanding specimen!
