I bought two Tiffany pieces at the Tiffany store. The ELSA PERETTI bean necklace in 9mm and the classic bead bracelet 10mm sterling silver. I ran the magnet over both the necklace and bracelet and the clasp from both sticks to the magnet. Now if its sterling silver like they claim it is its not supposed to sick to the magnet. the clasp does say on both 925 on it. Can someone who has the same necklace and bracelet test it out and confirm if urs sticks to the magnet aswell?
