Pilot Mountain Turquoise Navajo Ring with Bell Trading Post Stamp Sterling Size 10

1930s Navajo sterling silver ring with early Bell Trading Post mark. It is set with a natura Pilot Mountain turquoise stone that looks different colors in different lighting. It spends more of it's time looking on the green side, but I was able to catch it looking blue for the camera. This stone is not stabilized. 

The ring is very bright white silver and is likely has a much higher silver content than 925. It has the old Bell hallmark. 

Size 10 and the face is 1" wide. Weight: 15.1 grams. Fred Harvey era.
