With proper care, your pearl jewelry will maintain its beauty for generations. Follow these simple guidelines to keep your pearls lustrous and elegant.
Daily Care
Put pearls on last when dressing - after makeup, perfume, and hairspray
Wipe gently with a soft, damp cloth after each wearing to remove body oils
Avoid contact with cosmetics, perfumes, lotions, and hairsprays
Remove pearls before swimming, showering, or exercising
Don't wear pearls while applying makeup or styling hair
Storage
Store separately from other jewelry to prevent scratching
Use the soft pouch provided with your purchase
Keep away from direct sunlight and heat sources
Avoid plastic bags - pearls need to breathe
Store flat for necklaces to prevent stretching
Keep in a cool, dry place with some humidity
Cleaning
Use only a soft, damp cloth - microfiber or cotton
Never use ultrasonic cleaners or steam cleaners
Avoid harsh chemicals, detergents, and abrasive cleaners
Don't soak pearls in water or cleaning solutions
Let air dry completely before storing
Pro Tip
Wearing your pearls regularly actually helps maintain their luster! The natural oils from your skin keep pearls hydrated and beautiful.
Things to Avoid
Chlorine (swimming pools) - damages pearl luster
Salt water - can dry out and damage pearls
Vinegar, lemon juice, or other acids
Hair spray and perfume - contains alcohol and chemicals
Excessive heat and direct sunlight
Storing in a safe deposit box for long periods (too dry)
