Copper (fine crystallization) (ex Dr. Gunther Grundmann Collection)

Item Description

Tsumeb is world famous for producing many of the finest examples of various mineral species. Good crystallized Coppers are not terribly common from Tsumeb, but this piece is a very fine quality and beautiful display specimen. The piece shows two generations of crystallization with small, very sharp, well-formed, modified cuboctahedral crystals sitting on almost "feathery" arborescent spines of crystallized Copper. The piece has a gorgeous patina with an almost reddish hue in areas. As I said, the actual crystals of Copper are small, but they are really sharp and beautiful up close. The piece is nearly a complete "floater" as it's crystallized all over with only a few minor points of attachment. I think the piece resembles a plant or a bush with small "berries" sprinkled all over. A wonderful Copper specimen for any native element collector or a fan of Tsumeb minerals. The piece comes with a label from the collection of Dr. Gunther Grundmann in Germany.
