Guilin chicken blood jade seal
As a new jade, chicken blood jade has become more and more recognized and liked by people because of its colorful colors, especially the shades of red. However, many people are not aware that this new jade is quite similar to Guangzhou. Its hiding place is the source of Panyu’s senior jade expert Huang Yilin. How is it discovered? What kind of characteristics and value does Guilin Chicken Blood Jade have? What is the pros and cons compared with Changhua Bloodstone? In this regard, the reporter interviewed Huang Yilin and other jewelry and jade experts.
Guangdong people discovered Guilin chicken blood jade
As a senior jade expert who studied at the Department of Mineralogy of Sun Yat-Sen University, before and after 2000, when Huang Yilin saw the chicken blood jade stone in a jade trading market in Guangzhou, with a keen sense of consciousness, he judged that this should be a new mineral. . "At the time, they were sold to Guangzhou as ornamental stones. At first glance, they felt like Changhua's bloodstone. Red, black and yellow. The colors are mixed in a stone, and the colors are smart and layered. Feeling, especially red, bright and dripping, very eye-catching. But I measured it a little and tested the hardness, I know that unlike the bloodstone, it may belong to the silicon jade, it should be a jade carving material with good stability." He introduced.
After such initial cognition, Huang Yilin began to search for its place of origin: initially, he went back to Zhangzhou along the Pearl River, and went to Liuzhou, and inquired, or came from the river; then he came to Guilin, when Guilin sold There are already many merchants who have washed the water, but Huang Yilin is not satisfied, but still wants to find its original mine. "Everyone only knows about it. It is Sanjiang. From Guilin to Sanjiang, there are more than 80 kilometers. The next day I took a bus to Sanjiang. On the way, I saw many gold rushing boats in the river dig gold mines. At the same time, they also picked up the colored pebbles in their mouths and sold them on the shore. I think the stones in the river must have been rolled down in the mountains. The upstream of this river should be the location of the original mine. So I am going upstream. After two days, I went to the upper reaches and found that the colorful pebbles in the river are getting bigger and bigger. I think it should be not far from the destination.†In the end, Huang Yilin found its original mine in a place called chicken feet. Nearly 2000 meters, there is a large talc mine with conditions for mineral symbiosis. Huang Yilin took another small bus every day and entered the Shalin Village of the mining area. The roadbed that passed through was broken with this colored pebbles. When I got out of the car, I climbed to the top of the mountain. In front of it was a large stone covered with moss. Huang Yilin unveiled the thick turf, and there was a bright red "blood color" below. At that moment, he was as excited as discovering the New World.
Because of the jewelry company that has been doing it for a long time, Huang Yilin understands that this colored pebbles have great development value and should be introduced to the market. Under his efforts, Guilin Chicken Blood Jade was quickly developed and utilized.
However, at the beginning, this jade was called Caiyu, Red Jasper, and Red Jade. In 2014, it was officially named Guilin Chicken Blood Jade. Zhou Yunde, vice president of Guilin Chicken Blood Jade Association, said: "The original mining area of ​​Guilin Chicken Blood Jade is in the grounding zone of the Earth Plate. It was originally a submarine volcano. It was formed after a billion years. If it is ordered, it should be able to be mined for 50 years."
Wu Guozhong, former dean of the Jewelry College of China University of Geosciences, gave a more professional statement: "Guilin chicken blood jade belongs to jasperite, its chemical composition is mainly 70%~80% of silicon oxide, 10%~15% of iron oxide, and it has a blocky shape. Structure, strip structure, stripe structure, mottled structure, the pattern is ever-changing, the structure is mainly cryptocrystalline structure and microscopic crystal structure, so it is very fine, polishing performance is good, waxy, grease luster, after polishing Glass luster."
Suitable for the scary and precious resources
The precious thing about chicken blood jade is that it has the red color that Chinese people always like.
At the same time, due to its diverse background, it is especially suitable for making beautiful and beautiful carvings. For example, the "Zhong Yuxiang" exhibited this time, it is very infectious. The original stone itself has a variety of textures, and it also has the ornamental value of strange stones. Some look like the terraced landforms of Guilin, while others show the taste of Chinese paintings, like landscapes.
Tan Weibin, director of the Guangdong Provincial Arts and Crafts Museum, said that five years ago, when he saw Guilin chicken blood jade at the fair, he was deeply attracted. The main things he saw at the time were red and black, and other colors were rare. Last month, he went to Guilin to do a field investigation, only to find that this jade species is red, yellow, orange, green, blue, purple and colorful, and there are black and white. In his opinion, it is more appropriate to call the chicken blood jade, the meaning of borrowing the bloodstone of the east wind, called Guilinyu or Guilin Caiyu. "The biggest advantage of this jade is that it gives the sculptor great imagination and creative space. It has endless possibilities. The colors are rich and varied, and its diversity even exceeds that of Dushan jade in Henan. And because of the current national standards Not yet out, the price of Guilin chicken blood jade is not expensive, compared with the bloodstone, the difference is about a thousand times." He said.
Huang Yilin emphasizes that the individual specifications of chicken blood jade are relatively large, so it can be made into a giant system with a weight of ton. From the perspective of the use of Chinese gemstone materials, only the jade jade in Liaoning has such a large volume, but the color of jade jade is relatively simple. And the color is cold.
However, for the current engraving of Guilin chicken blood jade, Tan Weibin bluntly said that he could not compliment, can only say that he was in the primary stage, and at least three or fifty years away from the engravings in Guangdong and the engravings in Suzhou, so Many people are more willing to collect rough stones. "If there is a jade carving master or an artist involved, it is necessary to improve the position of the creative work in the real world. The future is not limited, but there are too many shoddy products, which is a great waste of resources." He regretted.
In addition, Tan Weibin reminded that through this inspection, he also found that because Guilin chicken blood jade price is low, some people in the market take white chicken blood jade to pretend to be the Qinghai material Hetian jade, "contrast carefully, you will find the structure of the two. Very different, Guilin chicken blood jade quartz content is high, the particles are relatively large, more loose than the tremolite jade, therefore, the water is strong, the oil is poor."
Guilin chicken blood jade grading standard:
Fresh and brittle side is good
The high-quality Guilin chicken blood jade must be bright, the texture is warm and delicate, and the sound is crisp. Geologist Zhang Jiazhi made the following classification:
1. Orphaned chicken blood jade
All red or full red with golden, pure black, jade should be condensed and gorgeous, jade color should be dazzling, color matching is excellent, and there are auspicious patterns or images, such as dragon-shaped lines, human-shaped lines, birds and beasts Patterns, landscapes, etc.

In addition to the three main colors of red, yellow and black, there are also the best chicken blood jade of red and brown.

4. Color mixed color chicken blood jade
Only irregular scatter or irregular broken red to dark brown, and variegated mixed jasper without red tones.
Guilin chicken blood jade PK Changhua bloodstone
One win is more stable
One win in cultural taste
Changhua bloodstone has long been famous in the world, then, what are the similarities and differences and advantages and disadvantages of Guilin chicken blood jade compared with Changhua bloodstone? May wish to analyze from the following aspects.
From the naming point of view: Why is a jade called a stone?
This should be from the physical point of mineralogy, the standard of jade is that Mohs hardness is below 4 for stone, 6.5 for jade, and above 8 for diamond. The Mohs hardness of Guilin chicken blood jade reaches 6.5~7, so it has good stability, high temperature resistance, acid and alkali resistance. The bloodstone is a mineral such as pyrophyllite, which is relatively soft and has a Mohs hardness of 2.9, so it is not resistant to acid and alkali. Huang Yilin said: "In the past years when there was no machine assistance, the Chinese prefer to use softer stones, such as Qingtian Stone, Shoushan Stone, Bloodstone, etc. Now, due to scientific and technological progress, in terms of material use, our freedom It is much higher in modern times, such as jade and agate. The West has always been aware of minerals mainly from a physical point of view, so they value physical stability and hardness as a standard to measure the value of jade. Their philosophy is that the harder and rarer the jade is, the more precious it is. The traditional Chinese concept holds that a gentle, restrained, and easily carved stone is better."
However, as far as the seal stone is concerned, Guilin chicken blood jade is really too hard to compare with Changhua Bloodstone. "The hardness of the bloodstone is moderate, and it is easy to change the content and font of the sculpture according to your own heart. The chicken blood jade must use machinery, and the room for the engraving is not so big. So it is necessary to adapt to each other. His own function." Zhou Yunde said.
From the perspective of historical and cultural connotations: Changhua Bloodstone is one of the four major Indian stone carvings. Since the Ming Dynasty, it has been favored by the aristocrats of the princes and has precipitated the humanistic value of 600 years. This is undoubtedly unparalleled.
Shao Chengxin, a representative inheritor of the intangible cultural heritage of Zhejiang Province, told reporters: "History has always been loved by the Ming and Qing Dynasties, except that because the Chinese admire the red, the red color of the bloodstone is cinnabar. In the past, it was the warlock alchemy. The raw materials have the cultural meaning of evil spirits. In addition, the hardness of the bloodstone is really suitable for the seal."
However, as a result, the current source of Changhua Bloodstone is nearing exhaustion, with little stock and lack of success. Guilin chicken blood jade currently has seven mines, each of which has a certain amount of storage, as long as it is reasonably mined, it can last for a long time. Of course, things are rare, Zhou Yunde said, a 3 × 3 (cm) high-quality Changhua bloodstone seal, the market price may reach 3 million yuan, and the same specifications of Guilin chicken blood jade seal, the highest Three or five thousand yuan.
Seen from red: the two are very different.
Changhua's bloodstone is red, because it contains mercury sulfide (the main component of cinnabar); Guilin chicken blood jade is red because iron ions work. Therefore, the red color of Changhua Bloodstone is granular, like sticking in the stone, looks very dignified, and very red, its bottom is generally gray, yellow. A stone full of blood reaching more than 70% is very expensive. The red color of Guilin chicken blood jade is flowing, even if the whole piece of red, there is a change in the intensity of each place, a little bit of maple leaf taste.
At the same time, Zhou Yunde said: "Mercuric sulphide is harmful to the body, it is not suitable for playing, and it will be discolored by exposure or overheating. The iron element contained in Guilin chicken blood jade is beneficial to the human body, and it is good in acid. How long does the alkali bubble do not change color?"
In this regard, Shao Chengxin has different opinions: "Changhua bloodstone contains mercury sulfide, but to reach a high temperature of 1700 degrees Celsius, it can extract mercury from it, the body temperature is not more than 30 degrees Celsius, it is impossible to be affected. In addition, the temperature is relatively high. In the case of the bloodstone, the color of the bloodstone will change, but it is only the surface oxidation, re-polished with water sand, and it will be bright and fresh, and the impact will be small."
