Small polished pieces of pink coral for use in jewellery. Corals are marine organisms closely related to sea anemones and sea pens. They secrete an external skeleton of calcium carbonate, often brightly coloured, which they extract from the surrounding water. Colonies of coral polyps gradually build vast reefs of coral, each new inhabitant building on the empty skeletons of its ancestors.
