Gemological point: The coral is a gem of organic origin. Only the branched limestone trunks of some corals are used in jewelry. Coral gets its color from carotene, an organic pigment found in some plants and animals. The color varies from blood red to white, through pink, also called “angel skin coral”. Today, the majority of coral species are protected by the CITES convention because they are threatened with extinction.
