Cleaning guide on coral jewelry

Coral jewelry is extremely fragile as it is made of the calcified remains of microscopic animals. Composed of calcium carbonate, it does not react well to contact with chemicals or acids. You must be extremely careful when cleaning coral jewelry so that you do not scratch the surface or actually wear away at the coral itself.
1. Wet a piece of soft cloth with warm water until it is saturated. Avoid using hot water to soak the coral or the cloth because extreme temperatures of either hot or cold can damage the coral.
2. Gently wipe the surfaces of the coral jewelry to remove the dirt. Do not scrub or press down on the coral so as to avoid wearing away the smooth, polished top with excessive cleaning. You’d better clean coral regularly avoid having to scrape or scrub at ingrained dirt.
3. If you have to use brush to clean the coral jewelry, you can choose another way. Use a fingernail under the soft cloth to clean around a bezel rather than the brush to make sure that you do not scratch the coral.
Do remember to avoid touching the coral with any cleaner. You will probably need to clean the setting from time to time. You can select mild special jewelry cleaner.
