Coral is an organic gem. But only special varieties with beautiful colors are valuable. The chemical composition of coral is calcium carbonate. There are many colors, the most common is white. Flesh red, deep red and light rose colors are more precious. Corals are mostly dendritic, with concentric layers of pattern structure and center points on the cross section. Glass luster to dull luster. The texture is fine, flexible and uniform, the fracture is flat and opaque.

Coral is a cylindrical coelenterate. In the larval stage, it can swim on its own, but the tubular adult worm is automatically fixed on the calcareous bone pile of the ancestor coral in the early stage. The coral relies on the tentacles on the upper part of the nozzle to capture microorganisms and send it to the mouth. The inner cavity digests the food and secretes a calcareous substance to build its own shell.

Corals can reproduce rapidly by their own asexual reproduction-the method of division and proliferation. In pursuit of food and sunlight, corals grow up high and to the sides like trees pull out their shoots. The longer and taller they grow, the larger they grow, forming a tree-like group. Taking out one of them is graceful and beautiful. Become a natural artwork.

The above is the common cause of coral reefs. Coral reefs are loose in texture and cannot be processed into ornaments. Another type of precious corals are rich in color and firm and dense in texture. They are gem-level corals and are also very popular “treasures in the sea”. 하지만, this precious coral grows extremely slowly and yields little.

As far as the ecological environment of coral is concerned, it only chooses to inhabit in clean, warm and quiet seas, mostly distributed between 30 degrees north and south latitudes, along the Mediterranean coast and the Pacific Ocean with a water depth of 200-2 000m.

Corals are mostly white, precious and rare. There are three species: (1) 붉은 산호: 분홍색, flesh red, rose red, ranging from light red to deep red. There is a dark red coral, which is called abroad. 그것은 “Bull Blood Coral”. (2) 검은 산호: gray-black to black, relatively rare. (3) Blue coral: 파란색, very rare. An important source of coral, there are red corals produced in Japan and the Mediterranean in foreign countries. The black and blue corals produced in Cameroon are very precious and are mainly used for crafts and jewelry.
