I don't see any stamps but my wife said it is 24k over sterling silver.nut I am not sure. It is a really nice piece bran new I was giving this as a gift only wore it once I am more of a silver type guy.
No I don't see any markings on it but my wife said it was 24k over sterling sliver but I really don't know but it is a beautiful piece looks like it was never worn.
Do to its weight I have to charge shipping it is a very heavy chain and the reason I charge shipping is because I ship first class and they will get it to you in about three days.
