First grade quality Cuprite crystal partially pseudomorphed by Copper from the famous Poteryaevskoe Mine, Rubtsovskoe Cu-Zn-Pb deposit, Russia. It displays sharp Cuprite octahedron. Some areas of the Cuprite have been replaced and pseudomorphed by Copper. The Cuprite has very strong luster and light reflection. Complete all over.
