Pearls are an organic gemstone, so they are softer and more delicate than other gemstones. Substances such as perfume and hair spray can dull the lustre of pearls or cloud their brilliance.
Apply perfume, hair spray and other cosmetics before putting on your pearls. After wearing pearls, wipe them with a soft, damp cloth to remove any traces of cosmetic products and body oils. Wash the pearls periodically with a mild soap and a soft cloth to remove any build-up over the gems.
Never use harsh cleaners when washing pearls. Because of their delicacy, pearls should be stored separately, away from hard jewellery to prevent scratches and other damage. Store pearls wrapped in soft cloth or in a soft-lined container or jewellery box.
