Vintage Marquise Shaped Turquoise Sterling Silver Ring Approx Size 9

Vintage Ring. Unmarked sterling silver with a turquoise like stone in the center. I’m not sure if this is turquoise or a different stone. I put a picture in next to another turquoise stone so you can see the color difference. Other item sold separately. This is approx a size 9. Approx. total weight of ring is 9.6 grams. This has been worn and has wear. Just polished. I can’t tell you anything else about the ring.
