Diamonds may be one of the hardest substance known to man, but they are not impervious to dirt, dust and other assorted types of grime. This is especially true for diamond rings, which can easily become soiled from your everyday activities. Hand lotions, ointments, soap and even your skin's natural oils often create an unattractive film on your sparkly rock. Fortunately, it is cheap and easy to clean your diamond ring at home using a mixture of liquid dish detergent and warm water.
Mix one part mild, liquid dish detergent and three parts warm water in a small bowl. Do not use a dish detergent that contains chlorine.
Dip your diamond ring in the detergent and water solution. Use a toothbrush with soft bristles to gently scrub the diamond ring to dislodge dirt and buildup.
Place the diamond ring back in the bowl containing the detergent and water solution and let it soak overnight.
Remove the diamond ring from the detergent and water solution and rinse it off with warm water. If you are rinsing your ring off in the sink, make sure you plug up the sink first so you do not lose your ring down the drain. You may want to use a plastic or metal strainer to hold your ring while you are rinsing it off.
Pat your diamond ring dry using a clean, dry and soft lint-free cloth.
