Beautiful rare copper replacement agate set in sterling silver with copper accents. This ring is a size 6.75
Copper Replacement Agates, discovered in the Keweenaw Peninsula, are very rare copper-included agates from the Kearsarge Lode. These little beauties are banded agates where some of the banding is replaced by native copper. Copper Replacement Agates come from the 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.
Their discovery was founded by John and Frank Perona back in 1951. The secrecy of these stones were kept until the mid 90s. Now the word is out and the most prestigious collectors are seeking out the very best examples. These agates are extremely rare and very hard to find and extract.
