White gold is made from a base of gold which is rhodium plated. The rhodium gives the jewellery a bright white appearance. Diamonds are white precious gems that are often paired with white gold to create rings, earrings, necklaces or bracelets. When dirt, oils or residue build up on your white gold and diamond jewellery, it can dull the jewellery's finish and the gem's sparkle. Cleaning your white gold and diamond jewellery once a month with a homemade solution will restore its lustre and beauty.
Fill a small bowl or container with 1 cup of warm water, and add 2 or 3 drops of ammonia.
Place the jewellery in the solution, and allow it to soak for five minutes. Lightly scrub any dirt or residue on the jewellery with a soft-bristled brush.
Rinse the jewellery with warm water to remove any cleaning residue.
Dry and polish the jewellery with a soft cotton or flannel cloth to restore its shine.
