This is a large beautiful Native American men's ring. It is not marked that I can find but it does test as being sterling silver with turquoise, coral, onyx and mother of pearl inlay. I believe it might be Zuni. The ring appears to be sand cast. It is a size 11. The top of the ring measures 1-1/4 inches long. The ring is heavy and weighs 40.4 grams. There are stamped designs on either side of the ring. It is in very good condition but does have an age patina and could use cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
