Pearls are less durable than most gems. They are sensitive to acids, dryness, and humidity. If you wear cosmetics and/or perfume, put these on before wearing your pearl jewelry. When taking off your pearls, wipe them with a dry, lint-free cloth. If needed, clean your pearls with warm soapy water being very careful to not get water into the drill hole as the pearl may discolor. Dry your pearls flat on an absorbent soft preferably lint-free towel. Always store your pearl necklaces flat as the silk will stretch. Store pearls separately from other jewelry as they will scratch. Store pearls in a dry environment. Never store pearls in plastic bags, moisture may get trapped and cause damage.
