Marvelous combo specimen of Galena, Chalcopyrite and Pyrite from the famous Madan ore field, Bulgaria. The Galena cubes are shiny and light reflective with strong matt luster. The cubes have some truncated corners and superb penetration twinning. They grow on yellow Chalcopyrite crystals. Brassy Pyrite cubes are seen inside the Chalcopyrite. The specimen has an attractive arrangement. In good condition – some small nicks, contacts and back side cracks.

Splendid!
