Vintage Navajo wrought sterling silver ring. It is channel inlay set with turquoise in a mosaic design. The ring has a "D" shape from the side view, so getting a 100% accurate size by measuring on a mandrel is impossible. Approximate size is 10. 

The wide sides of the ring have hand stamping that has some smooth wear. The silver has a rich patina.It is a little over 5/8" wide. Weight: 8.3 grams. A nice early piece with a lovely patina. There is old silver polish that is a rusty brown color in some of the stamping.
