Gemology note: Coral is an organic gem. Only the branched limestone trunks of certain corals are used in jewelry. Its color is due to organic pigments close to carotene: ranging from blood red to white, passing through “angel skin” pink. Currently, most coral species are protected by CITES, the Convention on International Trade in Endangered Species of Wild Fauna and Flora.
