To help protect your jewelry, you should make it the last thing you put on in the morning and the first thing you take off at night. You should always store jewelry in a cool dry place. Wiping your piece with a soft, clean cloth before returning to storage will help remove body oil and dirt. If your jewelry has cultured pearls in the necklace, your hands should be clean when you handle it. Put perfume on and let dry before adding the necklace.
