This is a Native American inlaid turquoise, coral and mother of pearl ring. Approx. size is 5-3/4. Initials inside back of ring inlay are  "CJ".  As with many older pieces, Sterling is not marked inside band of ring, but it is sterling. 

I bought the ring for my mother many years ago. I don't think she ever wore it, just put it away. The inlaid bird is turquoise blue and the berries are red. Mother of pearl background. Almost 3/4" in length and 1/2" wide.

Never exposed to smoke, perfume, scent of any kind.
