Pearls are organic, which means they are made of a carbon compound. This makes them more susceptible to damage and deterioration than most gems. Pearl rings should not be worn on a regular basis, especially if you work with your hands. Pearls are easily damaged by physical contact, in addition to damage caused by exposure to soaps, perspiration, cosmetics and other chemicals.
Put on pearl jewelry, including rings, last when you are getting ready to go out and take them off first when you return. A pearl ring should be put on after you are done with your hair, makeup and perfume and taken off before you use any soaps, lotions or makeup removers.
Pull on the metal ring part to take the ring off. Never pull on the pearl.
Store a pearl ring alone in a soft bag, rather than in a jewelry box. Do not store it in an area with dry air, such as a safe deposit box. Ultra-dry air can craze pearls, or cause them to develop a series of tiny cracks.
Use a soft, damp cloth to remove dirt and oils from your pearl ring after each wearing. After several wearings, wash your pearl ring with a gentle soap solution in lukewarm water. Use a soft, natural-bristled brush to gently rub the pearl with the soapy water.
Keep your pearl ring in the bathroom or other area where it is exposed to high humidity on occasion. Pearls are grown in the water, so water and humidity is much less damaging than air that is too dry.
