MIARGYRITE with BAUMSTARKITE

SPECIMEN DESCRIPTION

An excellent and rare specimen of two sulphosalts from the San Genaro mine, Peru. Renowned for its high quality crystallized silver sulphosalts it is the Type Locality to three species: Argentotennantite-(Fe); Baumstarkite; Sangenaroite. This world-class small cabinet specimen shows botryoidal metallic grey Baumstarkite, the surface of which displays intergrown fish scale-like crystals, with rare crystals of Miargyrite associated with several other undefined Sulphosalts in the underlying matrix. Not only is this a superb damage-free crystallized specimen of these extremely rare species from this classic occurrence, but it is a whopper too. Ex Professor Werner Paar collection.
