Superb combo specimen of Chalcopyrite, Galena, Sphalerite, Pyrite and Quartz from Madan ore field, Bulgaria. Lustrous Galena cubes are decorated by yellow Chalcopyrite crystals. The Chalcopyrite has rich color and sharp crystals. Brassy Pyrite cubes with strong luster are seen at the top. Black Sphalerite and small Quartz crystals add nice accent. In very good condition – some small nicks and small outside edges cracks.
Excellent specimen!
