Vintage Native American Owl Stone Mosaic Ring

Vintage Native American Owl Mosaic Stone Ring This ring was actually my Grandmothers. I thankfully have loads of her jewelry and would love for someone to treasure this ring instead of it sitting in my jewelry box. I'm thinking this ring is from the 70's or 80's. I cannot confirm what the stones are but this ring is beautifully made and seems to be quality. It is also not stamped on the inside that I can see but I would like to say that it's silver as it is not magnetic. My ring cone measurement says that this is a little smaller than a size 5. My ring finger is a size 5 and I can squeeze this ring on my finger. This ring is vintage and shows wear, marks and some tarnishing but is in decent vintage condition. Smoke free home. Cross posted.
