Vintage Native American Turquoise Coral Sterling Ring best

Lovely older 1960's to 70's sterling silver ladies ring. This ring is a nice large size with the setting being 35mm x 24mm in size. It has no hallmarks but I do guarantee it to be sterling. It is a size 6. It features a genuine blue turquoise and red best coral cabochon. It has been professionally polished and will arrive in a nice ring box.
