Tetrahedrite, Chalcopyrite & Bismuthinite (Soregaroli Coll.)

Item Description

A rich and showy combination ore specimen from this well-known mine and the Art Soregaroli Collection. The hefty matrix is covered with lustrous, sharp, metallic-gray, tetrahedrite crystals, many having a nifty golden-brown chalcopyrite coating. Richly scattered about are sprays of tiny, splendent silver-metallic lathes of what appear to be bismuthinite crystals. They could be other sulfosalts, such as freieslebenite or boulangerite. Choice material.
