This is a quite exceptional specimen with Bournonite associated with Chalcopyrite on Siderite. Bournonite crystals over 1 cm have a mirror bright metallic luster and display many crystal faces of the orthorhombic crystal system. Chalcopyrite is brass-colored with a metallic luster. Both species are perched on disc-shaped, olive brown Siderite crystals. A great classic specimen form the Georg Mine that closed in 1965.
