Necklace engraved with "AMV". AMV is mainly used as an abbreviation for "Antica Murrina Veneziana," an Italian Venetian glass accessory brand. I received this as a souvenir, but I don't use it anymore, so please someone else use it. There are a few scratches on the edge, but they are not noticeable unless you look closely. See photo 4. Please purchase if you don't mind.
