Pearl Care and Cleaning
For all pearls only a soft cleaning cloth, a chamois, should be used to wipe them clean. Washing pearls is not recommended. Typically, it's the silk string that is dirty, so the strand should be restrung rather than cleaned.
All pearls can be damaged by chemicals, so the rule is that when getting ready for an evening out, pearls go on last, after cosmetics, hairspray, and perfume. Pearls also should be the first to come off, and then should be wiped clean. Pearls should never be worn in the shower, to the pool or to the beach. Perspiration, as well as body oils containing natural acids, can damage the luster of a pearl. Remember, swimming pools are chlorinated: Chlorine is an acid and will dissolve a pearl.
Protect pearls from other jewelry, including other pearls, even on the same strand. Nacre is made up of tiny crystals of aragonite and calcite. This makes them gritty like sandpaper—and thus potentially damaging to each other—and is the reason for the old "tooth test." Pearls should be also protected from rubbing against their nother.
Bench repair and setting
Always remove the pearl before doing any type of repair work.
