Always protect your jewellery from sharp blows, scratching, chemicals, sunlight and heat/cold. Store your jewellery in moisture-free places. If possible store them in a soft lined box or pouch with an anti-tarnish strip.
Your jewellery will age and tarnish naturally so if you want to keep your pieces in pristine condition, clean your jewellery regularly, using a professional jewellery cleaning product. Be aware of tarnish which may occur as a result of oxidation, caused by the interaction of silver or gold plated jewellery with certain elements such as oxygen or sulphur as well as with certain acids.
You should prevent swimming while 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.
