Is black coral worth?
Black coral is known as “ironwood†and is a valuable raw material for carving precious handicrafts. Usually people think that coral is a kind of plant. In fact, this is a misunderstanding. Black coral is a kind of coelental animal with a graceful and elegant color living in the ocean. It can secrete limestone bones of red and white, and clusters together to form dendrites, which are known as coral stones. Unprocessed coral raw materials are dull and glossy, and are almost glassy after polishing. Black corals usually grow on darker, concealed reefs or at the bottom of cliffs, and water depths below 20 meters are more common. It is shaped like a silk willow on the land, so it is called a sea willow. The black coral-like suction cup is tightly adhered to the seabed stone. Because it is difficult to collect and has a wide range of uses, it is regarded as a treasure of the ocean. Natural black corals are rare in existence. Six years ago, black corals that had only experienced less than 40 years of mining history were banned from being included in the International Endangered Species Protection Treaty. The jewelry made with it is a business card on the island of Hawaii. Black coral is famous for its black or dark brown bones, but its tissue is brightly colored. One of the characteristics different from other corals is that there are no symbiotic seaweeds in the polyps. They can survive in the deep sea without providing nutrients or relying on sunlight.
