Vintage Oval Chrysocolla Sterling Silver Ring

This is a beautiful vintage ring with a 20 mm x 21 mm oval green and brown matrix chrysocolla cabochon, I think. It's set in a sterling silver scalloped bezel with twisted wire around it. It is a size 6.
This is a nice well made ring and would make a great gift for someone.
I thought it was natural turquoise until I saw the enlarged picture I took with my high powered digital camera.
Well whatever it is, it's absolutely gorgeous and I'm sure you will enjoy it!
