Marvelous specimen of Galena cubes decorated by Chalcopyrite over Calcite from 9th Septemvri mine, Madan ore field, Bulgaria. Very attractive arrangement of Galena forming terraced structures. The faces are matt lustrous. Contrasting addition is yellow Chalcopyrite crystals. The Calcite crystals are quite uncommon, with cream color and unusual habit. Black Sphalerite crystals and small Quartz crystals are seen too. In very  good condition – some small nicks and contacts.

Choice specimen!
