This is a Native American sterling silver ring. It is not marked but has been tested. The ring is sand cast. It has three pieces of turquoise and one piece of red coral. All of the pieces are bezel set. There are stamped designs on either side of the ring. The ring is a size 12. The top measures 1-3/8 inches long. The ring weighs 20.4 grams. It is in very good condition but does have an age patina and may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
