I realy don't know but I have worn it and I have a hard time wearing stuff because it will turn on me and this never has I think it may be sterling silver thank u.
I cant see any writing sorry but all the rings I have had on auction I paid over $50.00 for and I have other rings from the same place and I wear them a lot and have had no problems with it and I cant wear just anything hope this helps god bless.
