Native Copper included in Calcite & Prehnite Keweenaw Peninsula, Michigan 6.4cm x 4.9cm x 2.8cm Ex. Kohnowich Collection

Description/Interesting Notes: A terrific example of native copper included in calcite and prehnite from Michigan!!! This specimen consists of a rich network of native copper distributed throughout a cluster of pale green prehnite crystals with several crystals of calcite, richly included with native copper, perched among them!!! There are numerous areas of exposed native copper and the native copper appears to be richly included throughout the prehnite crystals as well!!! Old material!!! The pics hardly do it justice!!! Must be seen in person to be fully appreciated!!! Good luck and be sure to check out my other exciting mineral auctions on ebay!!!
