Precious coral beads are made from harvesting deap-sea coral beds that are formed from the exoskeletons of the coral sea creature, and forming that coral into beads. Other coral beads are harvested from other sources of coral and died red. Corals of all kinds grow very slowly, and harvesting has depleted the world-wide supply. Regulations are beginning to protect them, much like ivory, but many places where coral is harvested are still unregulated.
