Coral General Information
Coral is created by sea life. It is the skeletal remains of coral
polyps. Red, pink, and white coral is mostly calcium carbonate. Black
and golden coral is conchiolin.
Coral is especially fragile. Protect coral from scratches and sharp
blows. Also avoid large temperature changes (such as leaving it be a
heater vent or in a hot car). Do not clean coral in a home ultrasonic
cleaner.
Coral is often imitated by plastic, glass, porcelain, and stained
bone. Natural coral has a distinctive wood grain texture which can help
identify it as the real thing.
