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 s smooth wear. The silver has a rich patina and is very white. May be higher silver content than 925. It is almost 1 1/8" long. Weight: 28.3 grams. A nice early piece with a lovely patina. Very chunky and rustic.
