Vintage Sterling Silver and Amethyst Women’s Ring

Bought it in Quebec City around 30 years ago. I think the design is a snake. Most of the rhinestones are missing. Still in its original box though. “925” stamp is on the inside of the ring. The diameter of the ring is roughly 1.7 cm. It fits on my ring finger which is size 6. Smoke and pet free home Reasonable Offers will be seriously considered.
