What kind of stone is this? Is it Native American? It is signed “sterling” and “0925” on the clasp.
Hello. Yes, this looks like a Navajo made necklace. Leaf work was very popular in the 1970s and 80s. The stone looks like it could be chrysocolla which looks very similar to turquoise and can have a Bisbee look like the middle stone of your necklace. Thank you for sharing.
