What should you pay attention to in the coral collection?

China's Taiwan's coral production has ranked first in the world for many years, and some excellent valuable corals are China's unique national treasures. However, according to a report released by the Taiwan Coral Reef Society, due to adverse factors such as climate change, environmental pollution and man-made fishing, the corals in Taiwan's offshore waters have been extinct, the number of exploitable species is zero, and the coral reefs in the deep-sea seas are sharply reduced. 12% of the amount of mining. The long production cycle, the scarcity of the number of deposits, and the harsh mining conditions, the gem coral is called "red gold", which is currently being popular and the price has soared.

It is understood that from the end of last year, the price of high-quality gemstones has doubled, and the value of appreciation and appreciation is promising. However, there are mixed fish and dragons on the market, and there are times when the shoddy phenomenon occurs. Consumers should pay more attention when purchasing coral crafts.

There are many kinds of corals, which can be divided into five categories: deep red coral, pink coral, pink coral, white coral and white coral. The color of red coral is naturally generated, and its valuables are also here. Some unscrupulous merchants use inferior corals or white corals as the core. They are coated with special coatings and coral powder layers. The red corals, such as small white spots and small black spots, are processed into precious red corals and peach corals. It is difficult for consumers to distinguish.

Gemstones are mainly seen in color, followed by size. The color depends on its density, the density is low and the density is high and the texture is jade. There is a simple way to judge, that is, soak in the water, wait a moment, look at the surface of the bubble, if the bubble is very fine, very small, then the gem coral is relatively high density, on the contrary if the bubble is relatively large, relatively loose It proves that the structure of the coral is loose and the density is small. The color is redder and the better the quality. The size of coral individuals is related to the age of growth. The larger the chunks, the longer the growing age is, the more precious it is.
