Turquoise and Red Coral Native American / Navajo Statement Ring

Make a statement with this gorgeous vintage ring featuring genuine turquoise, red coral, and sterling silver. Made by the artist S. Dickens, as noted by the signature on the inside, the ring is between a size 7 1/2 and 7 3/4. It has some black discoloration on the bottom side (not visible when the ring is being worn), which I imagine could be easily cleaned by a professional jeweler, but is otherwise in very good vintage condition.
