WR 346 does not specifically indicate that an item is sterling silver. Sterling silver is typically marked with "925," which signifies that it is made of 92.5% silver. The WR 346 mark could refer to a manufacturer's code, a specific design, or a model number, but it does not denote the metal's purity. Always check for the standard sterling silver markings to confirm authenticity.
