Vintage Native American Turquoise Inlaid Ring Sandcast Sterling Silver 925 Southwestern Indian Size 7

This is a beautiful Native American butterfly ring made of solid sterling silver, it appears to be sandcast, it is inlaid with beautiful blue turquoise Gemstones The ring is mid century modern Fred Harvey Era. I believe it to be Zuni. No Hallmark’s but it is guaranteed to be sterling silver. The ring is approximate size 7 maybe slightly smaller.
