Copper Replacement Agate Pendant 615

This necklace features a rare Copper Replacement Agate from the Keweenaw Peninsula in Upper Michigan. The copper agate is flanked by smaller copper nuggets on the hand forged sterling silver backing.

These copper/agates are not considered Lake Superior Agates, but are agates from Lake Superior area copper mines. Experts can’t agree on just how these agates formed, but in some way, the copper coming up as super heated steam met the silica materials coming down and filled the same vesicles.

Whatever the geology, it's just plain cool looking.
