What are the identification symbols stamped on jewelry?
1 Answer

What the identification symbols stamped on jewelry are vary from piece to piece. In most cases, jewelry makers add markings that signify which brand produced a piece and what its materials are. For example, Tiffany & Co. typically stamps its full wordmark and “750” on its 18-karat gold jewelry. Some jewelry may also feature other hallmarks to represent its manufacturing location, serial number and/or copyright. On 1stDibs, explore a large selection of jewelry.
