Corals are produced by tiniest life forms, which settled in the depths of warm seas in vast colonies, long before our time. The Coral cnidarian is covered by a fleshy skin and secretes a calcareous substance, from which there are built the branchlike structures of the of the Coral stems. They can grow up to 40 cm in height, the thickness of the branches, however, hardly ever amounts to more than four cm. Only at the forks the structures are a little thicker. And from these parts the valuable raw material is gained which will then be turned into pieces of jewellery, large Coral balls or carved objects.
