You can safely clean gold, platinum and natural diamond jewellery at home using lukewarm water with a few drops of mild liquid soap. Dip the piece in the solution, brush it gently with a soft toothbrush to lift oils and dirt from behind the diamond, rinse under clean water and pat dry with a lint-free cloth. Diamonds attract skin oils that dull their brilliance, so cleaning every few weeks keeps them sparkling. Avoid toothpaste, baking soda and vinegar, as abrasives can scratch soft gold. Between wears, store each item separately in its original box or a soft pouch, since a diamond can only be scratched by another diamond. Remove jewellery before swimming, showering, sleeping or gardening.
