The listing, Blue Ring has ended.
I was given these rings so I don't know anything about them, I feel that they are gold filled or plated this said they are very nice and beautiful rings. No they won't turn your finger green. The plating may become worn if you wear they everyday. If you put them in hot water on have them on when you put lotion on this is not good for this type of ring and will harm the finish. This said I don't think anyone that has gotten jewelry from me have been disappointed in it. Size 7
