Diamonds are very durable, but they still require proper maintenance. Diamonds can get smudged, soiled, and dusty. Lotions, powders, soaps, and natural skin oils put a film on diamonds and cut down on their brilliance. Clean diamonds glow because the maximum amount of light can enter the stone and return in a fiery brilliance. It takes just a little care to keep them that way.

• Do not wear diamond jewelry, especially rings, when doing rough work. Even though diamonds are one of the hardest materials in nature, they can still be chipped by a sharp, sudden blow.

• Chlorine can damage and discolor the mounting on your diamond jewelry. Keep your diamond away from chlorine bleach or other household chemicals. You should also remove your diamond jewelry before entering a chlorinated pool or hot tub.

• Clean your diamonds regularly using a commercial jewelry cleaner, a mix of ammonia and water, or a mild detergent. Dip the jewelry into the solution and use a soft brush to dislodge dust or dirt from under the setting. Better yet, take it to your jeweler to have it cleaned regularly.

• Always thoroughly rinse and dry your jewelry after cleaning and before storage.

• Avoid touching your clean diamonds with your fingers. Handle clean jewelry by its edges.
