How to take care of your C&Co. items We advise to store your pieces individually in their box so they don't scratch, rub off or get in a tangle. Try avoid extreme heat or humidity as this may cause your items to tarnish. We do recommend when dressing to put your jewellery on after you use products such as deodorant, perfumes, sun lotions, oils, nail polish remover as some chemicals in these may damage, discolour or loosen stones in your jewellery. Avoid keeping your jewellery in direct sunlight as this can cause your pieces to fade and discolour. Keep your gold vermeil and sterling silver pieces in a cool, dry, dark place. Over time silver will oxidise and eventually tarnish, but if you store your jewellery in a sealed or airtight box this will keep the air out that causes oxidation. How to clean your jewellery We advise to carefully clean your jewellery with a soft, chamois or non-abrasive cloth. You can use a mild washing up liquid with warm water and a soft toothbrush, then rinse with clean water and gently dry with a soft cloth.
