The old adage " A diamond is a girl's best friend" really applies to a diamond ring when it is clean, sparkling and looking its best. Whether your diamond ring is a recent proposal gift, or a vintage keepsake from your great grandmother, diamond rings are meant to shine and to be admired. Unfortunately, daily exposure to the elements, including lotion, skin oil and everyday dirt, can dull your diamond ring in no time.
Create a cleaning solution from a squirt of liquid dishwashing detergent, one teaspoon ammonia and a half cup of warm water in a small bowl or jar. This solution is safe for the diamond, other stones that may be incorporated in the setting and the setting itself.
Submerge the ring in the cleaning solution and let it sit for an hour as the everyday grime begins to lift from the ring.
Remove the ring from the solution and gently scrub the ring, the setting and the band with an old toothbrush. Be sure to use a toothbrush with very soft bristles and go very lightly. Hard bristles and an abrasive touch can damage and scratch the ring. Be especially careful if there is an engraving on the interior of the band. This is common in vintage rings and often the metal is soft. In this case, it might be best to gently rub with soft, cotton cloth.
Rinse the ring in clean cool water. For added safety, block the drain hole of the sink with a strainer or a cotton cloth in case the diamond ring slips out of your hands. You can also tie a piece of red thread to the ring while you are cleaning it. It will help you locate the ring if it slips down the drain or falls into a nook or crevice.
Dry the ring with a soft, cotton cloth. Cotton is a natural fiber and it's highly absorbent, which will ensure that the ring is completely dry.
