Red coral is an organic gem with pleasant color and bright texture, which grows in the deep sea from 0/00 to 2000 meters away from human/kloc. It is listed as one of the three organic gems alongside pearls and amber, and it is also listed as one of the seven treasures in the oriental Buddhist scriptures. It has been regarded as a rich and auspicious thing since ancient times. Natural red coral is formed by the accumulation of coral polyps, which grow very slowly and cannot be regenerated. However, red corals only grow in several straits (Taiwan Province Strait, Japanese Strait, Baltic Strait and Mediterranean Sea) and are restricted by sea areas, so red corals are extremely precious. Ornaments made of red coral are very popular with collectors, and the value-added of fine red coral is very rapid, which is valued by collectors.
The production of Aka coral in Japan is getting less and less, and the really big and good Aka coral trees are in the hands of Japanese collectors, so we have no chance to see the real thing. They don't accept it for future profits, they just like it.
Aka is a kind of red coral, which is found near the Sea of Japan. "Aka" is a Japanese pronunciation, it is not the name of color, and some people use the letter AK to express it. Because Aka is the best species of coral, because its color is bright red, red is black, red is like pepper, and red is like cow blood, so people ask for Chili red and cow blood red, and people who don't know why say Aka color. Insider's name: Aka, Niuhong Coral, Red Coral, Red Coral; Generally, it grows in the sea area with water depth of110-420m.
In addition to Tosa Bay in Kochi Prefecture, Japan's main producing areas are the five islands in Nagasaki Prefecture, Kagoshima Prefecture and the waters around Okinawa Prefecture.
The main producing area of Taiwan Province Province is in the northeast of Taiwan Province Sea, near Kaohsiung Sea and near Hongtou (near Lan Yu Island), and now it has basically disappeared. Near the sea area of Kochi, Japan, the output is small and the products are all good. The communication with Japanese fishermen found that the deep sea in Tosa Bay, Kochi Prefecture is usually between 300 meters and 400 meters, and resources have become less and less in recent years.
Environment: Aka coral grows on rocks or cliffs at a depth of 1 10-360 meters. Coral can grow well only when strong ocean currents bring oxygen and plankton.
Depth: The growth depth of the sea area in Taiwan Province Province is the deepest in Lan Yu, with a water depth of about 360 meters; About 15 nautical miles outside the Fifth Street in Yilan, also known as the coral with dark color, will be caught only at the depth of 50-60 meters, but the material is poor and the yield is not much.
Shape: Most plants of Aka coral are single branches, and a few grow in a fan shape, in which the white nucleus tends to the back and even clings to the back surface. The white core also has a glass texture, which is slightly transparent.
The average price level of Aka red coral is 2500-5000 yuan a gram. Because of the existence of white core and bug eye, the most suitable thing to do is ring face, so here is the price of Aka ring face:
The price of more than 2 grams of red coral is 5000 yuan-12000 yuan/gram, and the average price is about 8000 yuan/gram;
The price of 1 g -2 g red coral is 1000-7,000 yuan/gram, and the average price is about 3,000 yuan per gram;
The price below 1g is-2,000 yuan/g in 200 yuan, and the average price is around 1400 g.
The prices of Aka beads and carvings are slightly different from those of ring faces. The overall price of carvings is lower than that of torus 1/3- 1/2, and the price of round beads is higher than that of torus 1/3- 1/2. This is the real price of Aka today.
Attention should be paid to coral wearing, as follows:
1. Red coral was red and bright when it was first bought, but it became dark, dirty and faded after a while. In fact, in some cases, the problem is not the coral itself, but that it is not well protected when worn. The surface of red coral turns white after being worn for a long time. This is because the human body will sweat a lot in summer, and there are acidic components in the sweat, which will cause chemical reactions. The best way is to wash the red coral jewelry with clear water every night after wearing it to wash off the sweat sticking to it to prevent chemical reaction. If it turns white accidentally, you can rinse it with clear water, dry it with a soft cloth, and apply baby oil to restore the red color. Coral ornaments should not be worn for a long time in summer.
2. Red coral should not touch cosmetics, perfume, alcohol, salt, oil and vinegar. Coral structure is not dense and has gaps, so it is not suitable to measure density and refractive index with heavy liquid to avoid pollution.
3. Red coral has low hardness, so it should be stored separately when it is collected to avoid being scratched by other gems. When wearing, try not to touch hard things. Repeated rubbing will destroy the smoothness, smoothness and brightness of coral surface.
4. Red coral should pay attention to prevent long-term sun exposure and high-temperature baking, otherwise it will easily lose moisture and luster and even fade.
5. If the red coral jewelry is dirty, rinse it with neutral soapy water or clean water, and then dry it with a clean towel.
6. When maintaining the red coral, gently rub it with colorless waxy baby oil or olive oil, and leave it overnight to restore luster. In severe cases, it can be gently polished.
The above is the maintenance method of red coral. I hope those friends who love red corals but don't know how to maintain them will no longer be helpless and make their red corals brighter!
