Group, on a Chalcopyrite matrix, of complex Tennantite crystals with a tetrahedral shape and very rich with faces, very bright and partially coated by small Quartz crystals.

Tetrahedrite (silver rich variety) with Chalcopyrite and Quartz.
MB91AG1: Tetrahedrite (silver rich variety) with Chalcopyrite and Quartz
This elegant silver-rich Tetrahedrite with Chalcopyrite and Quartz has a long history with labels starting in 1925 by Franz Ding and ending with John S. White.
