I'm not sure what you mean by 50% silver...........is it stamped "925"? Thank you. It is gorgeous. Probably Mother of Pearl rather than opal with the onyx. I love the ring. Thanks for listing and welcome to Listia ;D
Lovely ring. I think you would receive more & higher bids if you could provide more info about the ring. You can click on "edit" and add a few sentences for clarification. Thanks & good luck!
