Please store each jewellery item separately from other items to avoid sharp surfaces which may scratch the lustre or silver. Store away from chemicals and out of sunlight. Ensure that perfume, hairspray and other chemicals are applied to the body, face and hair BEFORE jewellery is put on to help avoid the jewellery becoming dull and colours looking faded. The glass and the silver parts of the jewellery can be gently rubbed with jewellery cloths to remove tarnish. If the tarnish is particularly stubborn, the pieces can be dipped in jewellery cleaning solution, rinsed and dried.
