Baumhauerite
            from Lengenbach quarry, Binn Valley, Wallis, Switzerland
Special Info
Type Locality

A dark steel-gray thin prismatic Baumhauerite to 8mm with deep striations set in a vug with red-orange crystalline Realgar in Pyrite rich sugary matrix. There are also dark steel-gray minerals present without any form that may also be Baumhauerite or another related species.

We're certainly not experts in the rare sulfosalts and sulfides of Lengenbach and this specimen has not been verified beyond our sight ID.
