Superb Cuprite crystals in a cluster of razor sharp octahedrons. They are with perfect shape, metallic and lustrous. They grow one atop another with the biggest crystal at the top making excellent focal point. For references see the issue of The Mineralogical Record vol. 45, # 4, July-August 2014. In good condition – some contacts (seen on the photos). On acrylic base.

Excellent Cuprite!
