Here is a vintage sterling silver (not marked but tested) ring of Navaho design featuring a pretty turquoise stone in robin's egg blue that is oval in shape and bezel-set. The stone varies in color a bit, shading into a darker blue. There is some brown matrix and a bit of silver inclusion near the bezel. The stone is set off by a large, serrated silver feather. The top of the ring measures 1 1/8" X 1 1/8," and it is a size 7. The ring is in excellent original condition, of good weight (.35 grams) and construction, and is about 40 years old. It is comfortable to wear, sitting comfortably between the knuckles. It looks attractive on the hand, covering the top of the finger and overlapping only slightly onto other fingers.
