Solid gold jewellery is very low maintenance when it comes to daily wear, especially the higher the carat. However, if any tarnishing or dirt appears from the nature of wear - clean in warm soapy water with a very soft toothbrush and dry thoroughly.Sterling Silver
Sterling silver can naturally tarnish with exposure to air, the best way to maintain your silver jewellery when not being worn is to store it away in a fabric pouch and clean regularly in warm soapy water with a very soft toothbrush and dry thoroughly. Avoid wearing your silver jewellery whilst swimming as chlorine can cause tarnishing.
'Town Talk' silver or gold polishing cloths are recommended to use if tarnishing appears on your jewellery. You can find the polishing cloths for sale here
