Pearls are an organic gem and they require a very specialized care
that if done properly will protect them for a very long time. They can
be harmed by contact with many chemicals found in household cleaners,
perfumes, cosmetics and hair care products of all kinds.
Never use
toothbrushes, scouring pads or any type of abrasive material to clean
your Pearls.
Never expose your Pearls to dish or laundry
detergents, bleaches, powdered cleansers, baking soda or any ammonia
based cleaner like Windex.
Never use any type of ultrasonic
cleaner.
Never steam clean your Pearls.
Never use tarnish
remover or any type of jewelry cleaner advertised on TV as a miracle
cleaner.
Never store your pearls in any type of plastic bag.
Plastic can emit a chemical that will cause the surface of the Pearl to
deteriorate. 
Never
leave your pearls around a direct source of heat such as a fireplace
mantle, on top of a television set, or stove.
Never store your
Pearls in a very dry room or in a safe deposit box for a long time. Your
Pearls need a little moisture like your skin so that they will not dry
out.
Always remember that your Pearls should be the LAST THING
YOU PUT ON when dressing and the FIRST THING YOU TAKE OFF when get home.
Always
use only jewelry cleaners that are labeled as safe for Pearls.
Always
store your Pearls wrapped in a soft cloth or pouch and protected from
all abrasive objects.
Always wipe your Pearls with a soft cloth
moistened with water.
Always remove your Pearls if you reapply
hair spray, or put on perfume with a sprayer, both can damage Pearls.
Always
be aware of the type of fabrics you wear fabrics like Shetland wool can
damage Pearls.
Always remember that you are wearing a gift from
the sea and the better you take care of them the longer they will
maintain their warm glowing luster.
