"The neighbor of Hetian jade" appeared in Qinghai jade
There are a thousand words in the text: "Jade out of Kungang." Kunlun Mountain is rich in jade, which is one of the most important birthplaces of Chinese jade culture. Hetian jade is distributed in the Kunlun Mountains in the south of the Tarim Basin. There is also a jade species in the same Kunlun Mountains, that is Qinghai jade. Qinghai Yutong and Tianyu are in the same category of nephrite. They are produced in Qinghai, and the insiders also call it Kunlunyu. It is in a metallogenic belt with Hetian Yutong. The Kunlun Mountains in the east of the Kunlun Mountains, the north and the mountains in the mountains, and the distance between the two are about three hundred kilometers. It can be said that it is the neighbor of Hetian jade. Although the origins of the two are very close, Qinghai jade is quite different from the traditional Hetian jade. The price of Qinghai jade market is relatively low, and it is often used to pretend to be Xinjiang Hetian jade. The following Tibetan jade will tell you in detail about the neighbor of Hetian jade, Qinghaiyu.
Qinghai production area
Qinghai Baiyu Mine is under the jurisdiction of Golmud City, Qinghai Province, China. It is located in the sodium plateau of more than 100 kilometers along the Qinghai-Tibet Highway. It belongs to the plateau hilly area of ​​Qinghai Province in the eastern margin of the Kunlun Mountains. It is located in Nanli of Kunlun Mountain. Qinghai Baiyu and Xinjiang Hetian Yutong are in a metallogenic belt. The east of Kunlun Mountain is Qinghai Jade, and the north of Kunlun Mountain is Xinjiang Hetianyu. The distance between the sodium and the Tianyu jade mine in the west is only 300 kilometers. Therefore, Qinghai Kunlun jade and Xinjiang Hetian jade are closely related in geological tectonic background. They are basically the same in material combination, occurrence, structural and structural characteristics, and Xinjiang Hetian jade belongs to a metallogenic type, which is magnesia marble. Formed by contact with medium-acid magma. There are currently three jade mines mainly mined;
1. Sanchahe jade mine: Sanchahe River is the main producing area of ​​Kunlun jade. The early black leather materials and soil leather materials are prolific here. Due to its fine particles, white color and oily foot, it is loved by consumers. In addition to producing a large amount of white jade, white plus black, smoke purple, and violet are all popular varieties.
2. Tola Haigou jade mine: The sugar-coated white produced by the Tola Haigou jade mine has the characteristics of white but not fine and fine particles. It is currently a variety pursued by collectors. The “duck egg green†jade produced by this mine is also quite it is good.
3. Xiaoyao Huogou jade mine: The sapphire produced by Xiaozhaohuo has been widely accepted by the market due to its fine particle size and oily foot. Yangzhou people named it “Biqingyuâ€, and the sugar produced by this mine has white and yellow materials. Excellent variety. Qinghai jade is a single mineral jade composed of microcrystalline tremolite aggregates. The tremolite content is mostly greater than 99%, and the impurity minerals are less. According to the state of output, Qinghai jade is mainly divided into mountain materials, a small amount of mountain water and Gobi materials, but no seed material is found.
In addition to the above three major producing areas, there are also Jiubagou, and there are also output in Yangpiling, Baiyanggou and Yuya.
Qinghai material characteristics
Shape: The mining of Qinghai material has not seen the production of seed material. The current output is in the form of mountain material. These mountain jade have a rough surface and many angular shapes and are irregular blocks.
Block degree: The output of Qinghai material is large, the fracture is uneven, and the large surface is neat.
Outer skin: The outer skin of Qinghai material is the same as other mountain jade, which is the uneven surface of the hair. It is white, translucent and yellow-gray. For different colors of the skin, the industry has a different name.
Color: Most gray-white - wax white, used to call this "Qinghai White". Another "rice soup" Baiyushan material, yellow-gray, gives people a feeling of grayness. According to the appearance characteristics, the insiders vividly described the different varieties of Qinghai Mountain material as “Milk White Jadeâ€, “Mi Tang White Jadeâ€, “Pear Blossom White Jade†and so on.
Transparency: Most of the green sea materials are translucent, and the transparency is significantly higher than that in Xinjiang and in Russia. Therefore, the texture and dignity are insufficient, which seems to be somewhat light. In some Qinghai materials, the transparency is not uniform enough on the same piece of material. It is often that the partial block surface is translucent and the partial block surface is opaque.
Texture: The internal structure of Qinghai material is slightly thicker but more uniform, the texture is not delicate and slightly "nen", the head of the water (or "heavy weight"), waxy luster and lack of moisturizing luster like "condensation".
For higher transparency, it is easier to see white "brain flower" shaped stone flowers. Transparent and aura, often "waterline", "water dew" pattern. Cotton-like splitting and black-brown sable spots, "stone ribs", "stone nails", etc. are common jade in Qinghai mountain materials.
The color characteristics of Qinghai materials
Like the Hetian seed jade, Qinghai jade can be divided into white jade, topaz, sapphire, jasper, ink jade and sugar jade according to its color characteristics. However, the color characteristics are more abundant than Hetian jade. For example, the emerald green and gray-purple varieties in Qinghai nephrite are rare in traditional Hetian jade.
Qinghai white jade, mainly based on mountain materials, whiteness is generally good, mostly faint ash, but the fat powder is slightly owed, the grease is slightly weaker, the texture is more tender, but the head is more adequate, but the old-fashioned feeling is not as good as Xinjiang. Materials and Russian materials. Therefore, it is often referred to by people in the industry as water white. The quality of the old pit Qinghai is also very close to the Baiyushan material produced in Hetian, Xinjiang. The new pit Qinghai white jade is slightly tender. The finished products of Qinghai white jade carving are usually glassy, ​​but the oil is not strong, and the transparency is high, the sensory head is large, the matt light does not look soaked, but it seems dry and not oily, because most of the mining methods are Explosive blasting, usually the material will be hidden with a crack. Therefore, there is a certain risk in the opening of materials, and some seemingly large blocks can not make large pieces, so when purchasing Qinghai mountain materials, we must pay attention to the integrity of the material quality and the hidden cracks.
