Coral is a hard stony substance made by millions of tiny carnivorous (meat
eating) animals called polyps. Coral polyps are tiny animals that build
protective calcium carbonate skeletons. Polyps create the basic structure of
coral reefs with the help of single-celled algae. The natural red corals are
rare and precious. The less expensive bleached white corals are often dyed to
red and other colors for jewelry making. Browse our enormous selection of coral beads
