The listing, Authentic Turquoise Ring has ended.
This ring is not stamped silver, but it does tarnish, and needs a good cleaning. I don't believe it's silver. It is dark around the stone, but you can't see because of the pictures. It was very difficult to get a true picture of what the ring looks like. The stone is genuine, and the ring is not very big. If I had to guess, maybe a 5, but that is only a guess, and I'm not very good at guessing ring sizes. That's about all the information I can tell you. Good luck!
