Native Copper and Prehnite

Keweenaw Co., Michigan

10cm x 9.93cm x 6.06cm


Description/Interesting Notes:

A rare and magnificent combination of prehnite and native copper from Michigan!!! This specimen consists of a cluster of lively mint green botryoidal prehnite crystals in a very rich and dramatic association with native copper crystals!!! These old time prehnite and copper crystal combinations are quite rare indeed!!! The prehnite is actually quite well crystallized, with surprisingly large indiviual faces making up the botryoids!!! The prehnite's color is a rich mint to apple green and is much better than the pics show!!! The copper is present in several crystalline forms, most notably the two large crystalline "lattice-works" present, numerous sharply euhedral single crystals scattered among the prehnite, and the ornate filigree that runs along areas of the prehnite!!! This specimen is absolutely stunning in person and there are rich networks of copper portruding from every possible side of this specimen as well!!! The pics don't even come close to doing this specimen justice!!! Good luck and be sure to check out my other exciting mineral auctions on ebay!!!
