Pearls are much softer than hard gemstones and can be easily scratched. Because they contain organic material and water, pearls can also crack if exposed to excessive dryness. In addition, acids and other chemicals can easily damage pearls.

• When wearing pearls follow the adage…last on and first off.
• Store pearls in a soft cloth sack, separate from metallic necklaces.
• Never clean pearls in an ultrasonic cleaner. Vibrations can shatter pearls, especially if the nacre is thin or cracked.
• Do not use chemical cleaners, especially those containing ammonia or bleach.
• Remove pearls before washing dishes, doing housework, or applying perfume or hairspray.
• Do not wear pearls in swimming pools with chlorinated water.
• Avoid contact with foods containing acids, e.g., fruit juices and salad dressings.
