Red, pink, orange, and black are among the most sought after colors of coral used in jewelry. These colors are typically found in the Mediterranean Sea, off the coast of Hawaii, near the Strait of Gibraltar, at the Cape Verde Islands (located off the coast of West Africa), off the coast of Portugal, and around Japan and Taiwan. The part of coral that is used for jewelry is actually not the living organism, but rather its carbonate secretions which form the structure that the polyps live on. Coral has been found in ancient Egyptian tombs, prehistoric European burial sites and historic jewelry from Tibet in as early as the 17th century. The Italians have always been known for their exquisite jewelry, and their use of coral is no exception. Through the 1800 and 1900s elaborate coral carvings were produced in Naples and throughout Italy.
