Attractive specimen displaying silver-metallic Galena with Chalcopyrite decoration from the famous Madan ore field, Bulgaria. Skeletal arrangement of Galena crystals overgrowing each other. Excellent parallel growth of cubes and elongated tetragonal prisms on different axes forming terraced structures. The Galena is matt lustrous. Yellow Chalcopyrite crystals grow above. They are well formed. Some black Sphalerite and Quartz crystals are seen too. Displays on both sides. In good condition – some nicks and contacts.

Interesting!
