Things that can be harmful to gold plating
Things you should avoid doing whilst wearing our pieces
In addition to above ensure you keep your jewellery in the box it came in to maintain its quality. If you lose this box any type of sectioned jewellery box will do. Try to keep your pieces stored on their own or not touching other pieces as this can be abrasive to the coating. To clean your jewellery use a soft jewellery cloth. Do not use anything harsh e.g. a toothbrush as this will wear down the gold plating faster.
PS - Last on, first off. A good rule to follow to keep your jewellery in good condition.
