Superb Cuprite crystal with the shape of razor sharp octahedron. It has perfect geometry, metallic and lustrous faces. Complete all over floater with one penetration twinning. On a strong back light the tips are slightly gemmy with red color. For references see the issue of The Mineralogical Record vol. 45, # 4, July-August 2014. In very good condition – some small nicks.

Excellent Cuprite from this closed mine!
