Looking after your Pearls. Pearls are organic, reasonably soft and don't like acid or alkaline environments. The easiest way to preserve their natural beauty is to put your jewellery on last, that is to say after you have applied make up, perfume and hairspray. Depending on the person even perspiration can damage Pearls, so just wipe them over with a tissue or soft cloth after wear, before storing them in a Jewellery box. The flip side of that is if not worn for long periods the pearls can dehydrate and this is also damaging. So wear them often, enjoy them and keep them away from chemicals!
