The ring is not stamped, as it is an author's work and the craftsman is not allowed to put a government sample, as factories that are engaged in mass production of jewelry do, but I give a 100% guarantee that this is real 925 silver and natural, agate. At your request and for an additional fee, I can order a gemological examination certificate with a state stamp. If you find yourself attracted to it, I highly recommend that you buy it now. This is a lovely item to own or to give as a special gift.
