Gemological point: Coral is a gem of organic origin. Only the branched calcareous trunks of certain corals are used in jewellery. Its colour is due to organic pigments close to carotene: varying from blood red to white, passing by the pink “angel skin”. Currently, most coral species are protected under CITES, the Convention on International Trade in Endangered Species of Wild Fauna and Flora.
