Sterling Silver Mother of Pearl Ring

I have to admit I don’t know a lot about this ring. It appears to be sterling silver, and does have a stamp, I am just not familiar with this specific stamp. It looks like either a “SS” or “JJ”. I believe it is a southwestern style ring. If anyone knows, please leave me a comment. It’s well made, and the design is really gorgeous and elegant. It is a size 7-7 1/2. Silver is still bright, and it’s a very comfortable to be to wear. EUC!
