White coral beads are cut from bamboo coral and are most likely bleached to achieve maximum whiteness. Since coral is softer than other gemstones, these semiprecious beads should be stored carefully to avoid blows and scratches. Cosmetics, hot water, chemicals and bright sunlight can damage coral. To clean these white coral beads, wipe them gently with a moist soft cloth. Coral is said to calm and improve life, protect children, and help difficulties of the lungs and digestion. It's also said to help restore harmony in the event of emotional conflict, and to work against nutritional deficiencies, depression, and lethargy.
