Try to keep pieces apart so they don’t rub together. - Your jewelry will age and tarnish naturally so if you want to keep your pieces in pristine condition, clean your jewelry regularly, using a professional jewelry cleaning product. - Be aware of tarnish which may occur as a result of oxidisation, caused by the interaction of silver or gold plated jewelry with certain elements such as oxygen or sulphur as well as with certain acids. - Never go swimming wearing your jewellery, as chlorine in swimming pools can cause damage to all metals and will erode gold jewellery. - Avoid wearing while cleaning, gardening or performing sports activities.
