Here's a classic vintage Native American handmade silver Thunderbird ring, inlaid with turquoise, coral. MOP and other shells. The face of the ring measures 1-1/8 long. Weighs 3.5 grams. As is the case more often that not with the earlier Native American jewelry, the ring is not marked for silver content or maker. However, I have tested the silver content and I guarantee that it is coin silver (.900/90%) or sterling silver (.925/92.5%). Excellent vintage condition. Size 5-1/2.
