Coral grows at a depth of 200 -2000 meters, which is extremely difficult to mine. Coral grows one inch in 20 years, and only one kilogram in 300 years. For thousands of years, despite the wind and waves, it still stands. It is for this reason that coral has become a unique Millennium treasure in people's minds.
Coral is a calcareous skeleton secreted by coral, so corals with loose texture and gem-grade processing density are very rare and extremely precious. Up to now, precious corals cannot be produced by artificial breeding, and their survival and growth conditions are influenced and limited by many factors in the natural environment, such as sunlight, water temperature and pressure of seawater, salt content of seawater, flow rate, food richness and health status. Due to the increasingly serious marine pollution, it is difficult to collect precious corals in the deep sea, which shows their rarity and preciousness.
There are many kinds of corals, which can be divided into white corals, light pink or dark corals and pink corals. You can see black corals (that is, sea trees) in Hawaii. Among them, red coral, blue coral and black coral are the most precious. Take red coral as an example, there is a saying called "Millennium Coral Wan Nianhong". Red coral is precious because of its slow growth, long life, strong quality, bright color and rare output. /kloc-In the middle of the 0/6th century, the red coral trade along the Mediterranean coast was very prosperous, thus creating many valuable red coral masterpieces. The harvest of red coral in the world today is between 100 tons and 400 tons every year, and its price is several times or even dozens of times that of gold. In many auctions, the price of red coral works is also surprisingly high. When coral is made into exquisite ornaments or carved into famous works of art, its value doubles. A good red coral necklace is worth several thousand yuan, and the highest one can reach tens of thousands of yuan. In particular, some exquisite and precious corals produced in the Strait of Taiwan Province Province, China, are unique national treasures in China.
From the artistic and cultural point of view, a coral sculpture is no less difficult and challenging to create than any other works of art, and each coral has a different shape. Only after careful design, ingenious conception and careful carving by craftsmen can it become a handicraft, so each coral work is unique and unique. For this reason, people are keen on collecting valuable coral works of art, which is reasonable. There are many exquisite coral collections in the Louvre, and many museums in China also have rich coral collections.
