General Care: When cared for properly, pearls can last a lifetime. Put your pearls on last when getting ready and make them the first thing you take off when you come home. Keep them away from household chemicals including perfume, makeup, hairspray as they dull the lustre of your pearls. Before putting your pearls away, wipe them with a soft cloth and store them separate from other jewellery to avoid scratching their tender surfaces. The best way to care for your pearls is to wear them often as the body’s natural oils keep pearls lustrous.
