Vintage Mexico Silver Carved Face Black Onyx Ring Size 7.75. Shipped with USPS ground advantage. You will receive the exact ring pictured. It is pre-owned, however, in very good condition! It is a size 7.75 and is signed Mexico silver. I'm not 100% sure if it's actually 925 sterling silver or some kind of nickel blend. Either way the ring is absolutely beautiful!
