To clean your diamond ring, soak it in a warm solution of mild liquid detergent and water. Ivory dishwashing liquid is a good choice, but any Other mild detergent is fine. Use a soft brush if necessary to remove dirt. Soft is the key, don?t use a brush with bristles that are stiff enough to scratch the ring's metal setting. Swish the ring around in the solution, and then rinse it thoroughly in warm water. Close the drain first, or put the ring in a strainer to keep from losing it. Dry the diamond ring with a lint-free cloth.
