Put them in a bowl with warm water mixed with a small amount of washing-up liquid.
Soak them for several minutes. After that, gently brush them over with a soft bristle toothbrush paying attention to the diamond’s edges and the prongs holding the stone to remove any grime build-up.
Be extra careful when cleaning eternity and half-eternity rings, engagement rings with small diamonds on the band and diamond bracelets.
After cleaning, rinse the jewelry with warm water. If you are rinsing them over a sink, make sure you close the drain.
Gently dry your diamond jewelry pieces one by one with a lint-free cloth to ensure they are completely dry before you store them away.
Never use harsh chemicals such as household cleaners or abrasives such as toothpaste to clean your jewelry, as this could damage the gold or other precious metal the diamond is set in.
