Thanks for sharing. These all look 1970s - 80s. All of the pieces look Navajo made. They call the squash blossom style shadow box. The five stone bracelet looks to be by the same artist as the necklace, I could not find anything on the hallmark. The bracelet looks to be Sleeping Beauty Turquoise, can not tell on the necklace but appears to be different from the image. I don’t know if that ring is Native American made, doesn’t look like something you see often. The last bracelet looks to be a piece of water web Kingman. I find a name associated with that hallmark John Charley.
