To care for your pearl necklace: 1. Wear your pearls regularly. Your body's natural oils help maintain pearls' beauty. 2. Apply cosmetics, lotions, perfume and hair spray before putting on your pearls. 3. Wipe your pearls with a soft cloth after wearing them. 4. Remove spills immediately with a slightly damp cloth and then dry with a soft cloth. 5. Store pearls separately from other jewelry, preferably in a slightly damp linen cloth to prevent the pearls from drying out. 6. Have your pearls restrung every two to five years if worn regularly or when the silk becomes dirty. 7. Don't wear pearls with jewelry made of metal or other material that may scratch the pearls. 8. Avoid contact with salt water, chlorinated water or perspiration. 9. Never use an ultrasonic jewelry cleaning machine or steam cleaner.
