This is a vintage Native American Zuni petit point turquoise sterling silver ring. The ring is not marked but has been tested. The turquoise is all bezel set. There is a rope design around the center stones and applied balls along the edge. The ring is a size 8-1/2. The ring 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 dropping by.
