2. Don't wear your pearls constantly.
It's best to take off your pearl jewelry before doing any strenuous work that may make you sweat or get the pearls dirty, such as housework. In addition, take off your pearls before swimming or taking a shower.
3. Regular maintenance.
Check your pearl jewelry regularly to make sure there are no loose pearls. Pearls can be cleaned using water and a soft cloth, or soaps formulated tobe very gentle, such as baby shampoo. If you wear a pearl necklace frequently, you should have it restrung at least once a year. Make sure your jeweler sets a knot between each pearl in the string, to prevent the pearls from rubbing against each other and abrading their surfaces.
