How Can I Tell If A Necklace Is a Real Silver?
Look for a hallmark or brand anywhere on the jewelry. If you see the numbers 800, 925, 958 or 999 in a circle, there’s a good chance you have real sterling silver on your hands. Look for any signs of green or yellow discoloration. This is indicative of rhodium or nickel plating, which suggests your silver is fake. Silver is a very strong conductor. Put a piece of silver jewelry into icy water for one minute, then hold it in the palm of your hand. If it remains cold for an extended period of time, it could be real silver.
