Coral - information
Coral, or coral root, comes from the Indian and the Pacific Oceans, where it grows 10 to 15m underwater and is harvested by divers. In its natural state, coral looks like a small, branching tree, and may have a diameter of up to one meter. The interesting porous structure and bright red color of some varieties made coral a popular gemstone quite early on. Sometimes the surface of coral is made smooth and glossy through a polymer treatment, which allows for more diverse use as a gemstone. Contrary to many other types of coral, coral root is not on the endangered species list and can be worn without worry of environmental hazard.
