In order to avoid scratches, do not wear multiple diamond rings or rings with other gemstones on adjacent fingers. Pearl is one of the softest gemstones. One should wear clothing with material that is smooth when wearing a pearl necklace in order to avoid rubbing against the pearls.
Also, when gemstones are heated, the colour might alter or fade. Therefore, do not expose gemstones to prolonged direct sunlight in order to avoid overheating. When getting ready for a night out, jewellery should be the last thing you put on after applying make-up and should not come in contact with perfumes, cologne, hairspray or other chemicals.
