Superb Cuprite crystal with sharp octahedral shape and bedazzling luster from the famous Poteryaevskoe Mine, Rubtsovskoe deposit, Russia. It has perfect geometry, metallic faces and super mirror luster. Complete all over floater. For references see the issue of The Mineralogical Record vol. 45, # 4, July-August 2014. Better in person. In very good condition – some small nicks and inperfections.

Excellent Cuprite from this closed mine!
