Recently, I’ve been uprooting Greenstones and Copper Agates in my shop. Both these treasures make extraordinary jewelry, and both are difficult to find. Fortunately, over the past couple decades, I’ve been able to acquire some of both, in old collections, as well as hunting them on old Spoil Piles in the Keewenaw.

I rediscovered a stone from a few years back. I recall finding the large nodule in matrix, in the Kearsarge Lode near Calumet. I left the half-dollar size stone sticking our from its’ host rock, and just polished the face of it. I thought it was a Quartz/Epidote, salted with Copper specks (nothing remarkable). I just left it for a specimen. That stone sat around of a while, until the other day. I decided to cut the stone out of the matrix. I assumed the pattern would be the same throughout the stone.

You can’t imagine my pleasure and thrill to find that big nodule was a Large Copper Agate! This was the largest Copper Agate I have ever personally found. After cutting that stone from the host rock, enough remained to create an improbable Gemstone for another pendant.

Last week was one of the luckiest lapidary weeks I’ve ever had lately. Unfortunately I do not have any more mine rock with giant Copper Agate Suspects in them, but I can hope I find another big nodule out in the Lode. I’ll look this year.
