Sterling Silver plated copper bridal sets, with cubic zirconia like stones

these rings are sold as is. they were bought at a liquidation auction as sterling silver, however after getting them appraised we come to find them not Sterling silver but sterling silver overlayed over copper. as far as the stones, I don't know if they are cubic zirconia or not. prices will reflect that. we have many others as well that will be posted. I DO NOT KNOW SIZE
