This agate in an extremely rare Copper Replacement Eye Agate from the Wolverine Mine in Houghton County, MI. 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.

This piece also includes a Native Michigan Copper cab..
