Vintage 925 sterling silver turquoise ring, Southwestern Navajo, size 5.25

Vintage sterling silver Southwestern ring, handmade. With natural blue / teal turquoise stone that looks like Sleeping Beauty - one of the best kinds of turquoise (but can't guarantee that as I didn't take it to a gemologist). It's true color is shown best in the first and last pictures. Native American Navajo style. Delicate looking and not heavy. Stamped 925. Some wear on one of the front edges and partial tarnish due to age (which I can clean upon request). Otherwise in excellent condition. Size 5.25.
