I'm not sure, I do believe it is sterling silver, with a cubic zirconia, it was a gift, and I've never worn it. How ever it has remained beautiful in my jewelry. Kids didn't want me to list it on here. However, I feel that Listia has some very good people and we find what we want here for free and we use our credits to get what we want. Simple as that! If you want it enough you go after it. It is a beautiful ring, Pictures don't do it justice. Thank you for watching.
