Cute specimen of Chalcopyrite, Galena and Sphalerite from 9th Septemvri mine, Madan ore field, Bulgaria. Very attractive arrangement of Galena cube growing on yellow Chalcopyrite crystals. The Galena has truncated corners, matt luster and strong light reflection. Some black Sphalerite tetrahedrons grow around. In good condition – some small nicks and contacts.

Pleasing combo!
