For your consideration is this beautiful hand made ring. It has a gorgeous stone that I believe chrysocolla malachite with wonderful color variation. I believe the ring is native American Indian judging by design and research on this mark on the net but I can not find it in my books. The mark is Sterling 925 MFG.
The ring is a size 7 and 1/2. The face is large measuring 1 and 1/2 inches by a hair shy of 1 inch.
It is in excellent vintage condition with a nice patina. It has a little scratching to the back only. Stone is smooth and secure.
