Vintage Native American Turquoise & Sterling Silver Ring; Signed, Size 12 (somewhat measures between 12 & 12.25). Natural imperfections in stone, no cracks/chips/etc. Sterling is able to be read on inside, designer stamp is a tough one but will update if I do figure it out.

Measurements of stone: 18mm x 13.25mm, underside of band measures roughly 5 mm and would be sizable. Any questions please feel free to message me.
