Top quality combo specimen of Galena, Chalcopyrite and Pyrite. The Galena cubes are shiny and light reflective with 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 and outside edge contacts.
