Cuprite on copper-bearing Dolomite Kutnohorite black and golden cyclic twinned

black and golden cyclic twinned crystal groups of Cassiterite sitting on white prismatic Quartz crystals

and definitely one of the better pieces I've seen in terms of sharpness and fine crystallization

I love the fact that the outer rind on the front is complete all the way around

A lovely piece of gemmy golden Copal featuring approximately 50 insect inclusions

Cuprite on copper-bearing Dolomite Kutnohorite black and golden cyclic twinnedHere we have a wonderful matrix specimen of Cuprite featuring a sharp, well formed, dodecahedral crystal group of a dark metallic red hue measuring 1. 2 cm aesthetically perched atop matrix and associated with mint green colored copper bearing Dolomite. With strong backlighting, the Cuprite shows a slight bit of translucency around the edges, revealing a brighter red color. The combination of Cuprite with copper bearing Dolomite is RARE from Tsumeb,
