Your Pearl Jewelry should be the last thing you put on and the first thing you take off. Avoid any contact with chemicals, such as makeup, perfumes and hairspray. Put them on after you have applied these.
Care should be given when storing them, a soft silk bag or a cushioned box is perfect. When I sell a strand of Pearls I include a silk storage bag with them.
Clean your Pearls with a soft, moist cloth. A wash cloth is perfect.
