JCK 5: “Nevers” of Pearl Care to Tell Every Customer

1. Never hang pearls. This weakens the silk threads holding the necklace together.

2. Never store your pearls in any type of plastic bag. Plastic can emit a chemical that will cause the pearl’s surface to deteriorate.

3. Never leave your pearls near a direct source of heat (e.g., fireplace mantel, ­television set, stove).

4. Never store your pearls in a very dry room or in a safe deposit box for a long time. Pearls need a little bit of moisture or they’ll dry out.

5. Never allow your pearls to make contact with any chemicals found in household cleaners, perfumes, cosmetics, and hair-care products.
