No Hallmark; no Sterling mark ... but I know the folks I bought it from. They are in Arizona ... and have been for almost 40 years. They know Native jewelry. They know turquoise and this tests .925 sterling silver. The nugget stones and design tell the age - most likely 1940's (again before a lot of the Native silversmiths came to hallmarking their pieces- especially if done in masse. The stones are very special; the silver itself is sheet and trimmed .... but this is a cuff/bracelet for the generations. Slightly out of round ... not surprising for the age.
gap - 1.5"
