When you think of corals, everyone will naturally think of red corals! Corals are not only representatives of gem-quality corals, but also expensive, perfectly demonstrating the classical oriental feminine beauty. Therefore, in the hearts of the public, red coral is the label of coral!
However, there is more than one kind of coral, and people's understanding of it is still very limited. Corals are made up of substances secreted by polyps, the main component is calcium carbonate, and the organic matter content is very small. In addition to the most common white, corals have red corals, black corals, blue corals and golden corals. So corals are not just red in color! Corals resemble tree trunks, but they are not wood, but creatures, organic gemstones
Red Coral:
Red coral is a gem-grade coral, which belongs to organic gemstones and is a very valuable variety, because it is only one inch long in 20 years, and it only grows about 1 kilogram in 300 years! While red corals grow in deep-sea areas, red is gradually formed due to corals absorbing about 1% of the iron oxide in seawater during growth. Thus the color of the red coral will be different from dark to light, from dark red, bright red, pink to light pink.
The red coral color is pleasant, meaning auspicious and rich, and has always been regarded as a thing of auspiciousness and is favored by Chinese. In red corals, there are also grades according to color.
Top red: AKA red, dark red red coral, known as "ox blood red", that is, we often say Aka, is the most precious breed of red coral, not only in the East, but also in western countries is also very popular.
Secondary red: Commonly known as "pepper red" coral, also known as sardine red, commonly known as large red is second only to "cow's blood red." ”
Grade 3 Red: MOMO Red, Flesh Pink or Orange Red with Aka and Sardine are recognized as the three best varieties of red coral.
Grade 4 Red: ANGEL SKIN Red, also known as "Baby Face", is a pink coral named after the color similar to a child's red cheeks.
Grade 5 Red: Pinkish white, also known as "deep water material." ”
In general, the darker and more colorful the red coral, the higher the value, and according to the color level, Aka is recognized as the top red coral.
In addition to the most valuable and popular red color, corals of other colors are also very beautiful.
Coral In addition to red coral, black coral is also a dark horse character in the play circle!
Black coral is the most special of all coral species, and its main ingredient is not calcium carbonate! It is keratin composed of chitin, protein and organic matrix! Other corals start with icy cold, while black corals are mild! At the same time, black coral is divided into many types, including golden willow, blood willow, black willow, stone willow and so on!
Golden corals appear golden yellow or brownish yellow because golden corals are divided into diving golden corals and deep sea golden corals! The color of the two will be different! Deep-water golden corals can sometimes see special optical effects such as halo or color change, and golden corals under the light source, in addition to the metallic luster, are also accompanied by pink, yellow, blue, purple and other colors of halo. It is a valuable coral species that does not lose red coral among corals
It should be noted that now some people sell black coral fading as golden coral for huge profits, which is very hateful, and everyone should pay more attention when buying. After all, golden coral is not so easy to see, if the merchant exaggerates that they have a lot of gold coral inventory, then nine times out of ten are bragging! Be careful
Gold corals are rarer than red corals, so they are also more valuable. But perhaps because of the pleasing color and deep cultural heritage of red corals, red corals are more popular.
There are many varieties of corals, and corals are not good or not, the value is not worth collecting, in addition to looking at the color, but also combined with the origin of corals, as well as their own quality. In different countries and regions, due to the influence of religious beliefs and ethnic cultures, the popularity and market value of corals will also vary. In short, coral as a natural organic gemstone, coupled with its non-renewable nature (extremely long growth cycle, twenty years long by an inch), its ornamental and collectible value has been affirmed.
Of course, in addition to red coral, gold coral, black coral, there are also blue coral, white coral, stony coral, bamboo coral and so on! But the higher value is mainly red coral, golden coral, and black coral!
