An important tip: take off your gold jewellery when you take a bath or shower, go swimming, go into the sauna, wash your hands or go to bed. Also wait ten minutes or so between applying skin cream, lotion or perfume before putting your jewellery on again. Store your gold jewellery in the original packaging or in a jewellery box with a soft interior and separate storage compartments. Do you invest in gold? Then keep it in a safe at home or at the bank.
