Things You'll Need
Dish washing detergent
If your diamond and pearl ring is looking dingy or dirty, a cleaning is in order. Cleaning a ring with a pearl and a diamond must be done carefully. While the diamond is a stone that can withstand many chemicals, the pearl is a soft stone that can't. Strong chemicals and many jewelry cleaning machines aren't suitable for pearls. It is, however, possible to get your ring clean without damaging the stones.
Clean the ring daily using a jeweler's cloth. This will minimize the amount of dirt and grime on the ring. Alternatively, you can dampen a flannel cloth with warm water to clean the ring.
Mix one teaspoon of gentle dish washing detergent in one cup of warm water. Mix until sudsy.
Soak the ring in the mixture for five minutes.
Dampen a small brush, like an eyebrow brush, with the solution.
Scrub the ring gently using the small brush, dipping it into the mixture as often as necessary.
Rinse the ring off with warm water.
Wipe dry with a clean piece of flannel or jeweler's cloth.
If the ring is really dirty, go to a jeweler to have it cleaned. Using strong chemicals or "sonic cleaners" at home on a pearl may damage the stone and/or the settings. Check the stones on the ring to ensure they aren’t loose before cleaning the ring or wearing it. If any stones are loose, have a jeweler reset them.
