Early Tommy Singer, S with crescent hallmark. Peyote bird in turquoise and coral chip inlay.
Look at pictures and see quality and detail. Nice collectible sterling or coin silver ring(not assayed). Size 8.5 slightly adjustable however I would caution you to making it too much bigger as it may damage the integrity of the inlay. Band at base of finger is 4 mm wide. Top bypass section is 2 cm across.
Great history, Navajo silversmith highly collected and super ring! Fascinating learn if you have time about the Church of the Peyote!
