Superb combo specimen of Galena, Chalcopyrite and Pyrite from the famous Madan ore field, Bulgaria. The modified Galena cubes are shiny and light reflective with strong luster. They are twined and show some skeletal features. Among them grow yellow Chalcopyrite crystals. Brassy Pyrite cubes are seen in the Chalcopyrite. The specimen has an attractive arrangement. In very good condition – some small nicks and side contacts.

Marvelous!
