Avoid any prolonged contact with water, salty or chlorinated, perspiration or humidity in general. Remember to remove your jewellery when using chemicals or cleaning products, and other creams, perfumes or lotions of all kinds. When you are not wearing it, in order to retain all its shine, avoid leaving it in the open air or in the light. These few tips can significantly extend the life of your jewellery. Poor maintenance diminishes the gold layer.
