Cultured Pearl Care and Cleaning
Pearls are soft and delicate, but with special attention and care, your pearls will maintain their luster for centuries. When buying pearls, choose those with thick nacre to help them withstand wear over time. In a strand, make sure there is a knot between each pearl to prevent rubbing and to ensure that only one pearl will drop if the string breaks. Have your jeweler re-string your pearls every couple of years, especially if you wear them often. The silk thread used to tie them together breaks down over time.
To avoid scratches, nicks or chipping in the soft nacre, keep pearls separate from other precious metals or gemstones by storing them in a cloth pouch or jewelry bag.
Keep pearls away from household chemicals such as hair spray, cosmetics, perfume, alcohol, chlorinated water or other harsh chemicals, which can cause spots and blotches and dull their luster over time. To avoid these effects, pearls should be the last item put on when dressing and the first item removed after returning home. Because the body's natural oils keep them lustrous, one of the best ways to care for pearls is to wear them often.
Pearls contain an organic material called conchiolin. In time, this material will dry out, and high temperatures will destroy it. Perspiration sometimes contains acid that may dissolve the aragonite crystals making up the layers of nacre. Therefore, wash and dry your pearl jewelry gently after you wear it.
Wash cultured pearls in very mild, soapy water and nothing else. Wipe them with a soft cloth before storing them.
