Precious coral
Precious coral or red coral is the common name given to ''Corallium rubrum'' and several related species of marine coral. The distinguishing characteristic of precious corals is their durable and intensely colored red or pink skeleton, which is used for making jewelry.
==Habitat==
Red corals grow on rocky seabottom with low sedimentation, typically in dark environments—either in the depths or in dark caverns or crevices. The original species, ''C. rubrum'' (formerly ''Gorgonia nobilis''), is found mainly in the Mediterranean Sea. It grows at depths from 10 to 300 meters below sea level, although the shallower of these habitats have been largely depleted by harvesting.〔
〕 In the underwater caves of Alghero, Sardinia (the "Coral Riviera") it grows at depth from 4 to 35 meters. The same species is also found at Atlantic sites near the Strait of Gibraltar, at the Cape Verde Islands and off the coast of Southern Portugal.〔 Other Corallium species are native to the western Pacific, notably around Japan (''Corallium japonicum'') and Taiwan;〔 these occur at depths of 350 to 1500 meters below sea level in areas with strong currents.〔
