China’s Hetian jade has a thousand years of history, and it is recognized as the king of nephrite in the world. The preciousness and rarity of Hetian jade also attracts various businesses, and there are also many people who are mixed with fish. In order to let everyone know about Hetian jade clearly, here are some simple ways to identify Hetian jade:
First of all, introduce some common counterfeit products that pretend to be Hetian jade.
1. Marble: This jade color is mainly white, the gloss is waxy, and the internal structure is waterline and stripe.
2, water stone: the main component of this jade is quartzite, its hardness is high, but brittle and easy to break. The internal structure is a cryptocrystalline structure that is shiny and shiny. The color is pale and the gloss looks dry.
3. Meteorite: It is produced in Xiuyan County, Liaoning Province, and is another jade in China. The production of jade jade is large, the hardness is low, and it is easy to break. It is second only to Hetian jade in value. Its internal structure is cloud-shaped. Mainly green, mainly used to pretend to be Tianqing white jade.
4, emulsified glass: This is a pure counterfeit, artificial imitation according to Hetian jade with glass. It has no obvious structure and can be seen with a small amount of air bubbles inside the naked eye.
China Hetian jade has a long history, and it is famous for its splendid culture. It is an integral part of the splendid culture of the Chinese nation. Hetian jade is a reiki thing, it symbolizes a huge amount of wealth, but people often lack the eye for distinguishing between authenticity.
With the improvement of people's living standards, the high-end jade articles played by the aristocrats of the past have gradually entered the homes of ordinary people. So where does the collection of Hetian jade begin? How can I purchase the authentic Hetian jade?
First, look at the jade material:
Materials are the primary premise of jade collection, and high-quality jade is essential for a jade. At present, the usual price, the same level of jade is 6-8 times of the mountain material. In the market or online, it is more common to use the skinless mountain or Russian material, and the rice and rice materials are sold. The Russian material is also a mountain material and has the same material composition. The Russian mining material is called Russian material. The price is much lower. The characteristic is white, but the jade is too watery, it is too transparent, and the density and oil texture are both. Not as good as authentic and Tianzi jade! If it is sold in Russian materials and Tianzi materials, it is difficult to distinguish the less experienced ones. Currently, there are many in the market or online.
The real sheep fat jade, there is no standard in the country, it is produced in ice and snow covered glaciers. If the sheep fat is white, it is not only white but also not anti-green. Its oiliness is extremely high. It is not the same as the mountain material or the jade that the general color reaches the sheep fat grade. Some old players have been hard to find for decades. The fatness of the sheep fat jade is combined with its rarity, so the jade jade often finds the fat of the sheep fat, and it is difficult to feel the blue sky. It can be said that now that there is money, it is not always possible to buy the refined product Yangzhiyu.
Nowadays, most of them are self-proclaimed sheep fat jade. In fact, most of them are high-white mountain jade or son jade. For example, high-white jade without skin is mostly mountain material. The jade workers know that the price of the jade is several times higher than that of the high mountain. When doing work, you must try your best to keep the skin. Some people who try to make fake leather for the purpose of posing as a jade are also often seen. The skinless jade is not a child jade, it depends on the experience and eyesight of the appraiser, so it is often controversial.
According to the same level of Hetian jade, the sub-materials are the most expensive, followed by mountains and rivers, followed by mountains.
Second, identify the pattern decoration:
Modeling is the aesthetic framework of jade, and it is also an important factor in determining the value of jade collection. The shape is determined by the function and the shape of the jade, and the proportional trade-offs should be appropriate. Well-proportioned and not dull, balanced and stable is the beauty of the work.
The ornamentation is the decoration of jade, and its beauty and ugliness are easy for people to perceive and feel. Generally speaking, it is subject to the needs of the device type, or both of them depend on the needs of social functions. The decoration depends on the structure, the rules, the complexity, the sparseness, etc., and the structural rules are methodical, and the unity and harmony have the appreciation value.
Third, the analysis of fine art:
The jade craft is the technical condition of the material changer. Its nature is relatively stable and it is not easy to be recognized by people. It is a difficult problem in appreciation. Wherever the work is smooth and fluent, the skilled workmanship must be beautiful or relatively beautiful. On the contrary, the plate is sluggish and the water is muddy, which is a sign that the value of the collection is sharply reduced. Art is the highest level that every jade is pursuing and the hardest to do. All the vivid and vivid, both form and spirit are the expression of artistic beauty, reflecting the rich collection value. On the contrary, the craftsmanship is poor, the art is inferior, and the works of the ancients who violate the artistic beauty are much less appreciated. Therefore, in addition to paying attention to the material of jade, the jade collection should pay attention to the craft level of jade and pay attention to the artistic nature of jade. The reason is very simple. The better the material of jade, the rarer the stock in nature, the more difficult it is to process. The harder it is to make a good jade, the higher the value.
Fourth, try to buy leather dice jade:
A layer of maroon or brown-yellow jade skin distributed on the surface of Hetianziyu, so it is customary to call it a skin color jade. There are autumn pear, aloe, jujube, black and so on. The jade artist has a variety of leather colors with jade names, such as autumn pear skin, tiger skin, jujube skin red, golden sprinkles, black leather and so on. Many jade in the world have this color, but it is not as beautiful as Hetian jade. The use of leather color can make a pretty jade, which is naturally interesting, called Duplo.
The shape of Hetianziyu color skin is various, some are cloud-like, some are vein-shaped, and some are scattered. The formation of the color skin is secondary. Since ancient times, the price of the same skin color is much more expensive than the skin without the skin color. The splendid skin color is a unique feature of Hetian jade and a symbol of real goods. However, the fake ochre skin material is very common in recent years, and the ochre is mostly attached to the surface. There is no oil in the exterior, and there is no water head. It needs to be distinguished.
Buying leather dice has the following advantages
1. Ziyu with a stamp (national appraisal certificate), without controversy, can determine its value and value-added.
2. There is a saying in the line: "The material has gone to the skin and the gods can't recognize it." It mainly means that some high-quality mountain materials (even Russian materials) can be compared with the raw materials, but are sold by unscrupulous merchants at high prices, but the purchase price is several times different. Therefore, the nude jade without skin color is more controversial and difficult to maintain its value. Therefore, some people say that naked jade is controversial and cannot be guaranteed. The nude jade is black and white, and the leather color jade is a color photo. It gives the artist a full creative space and also gives people a colorful artistic enjoyment.
What is special about buying Ziyu:
Ziyu 99% has different material cracks or a little impurity, so the jade is called crack or septum. Generally, the large septum or the more obvious noise points will be modified when working, and the existing septum will fall within the normal range without affecting the appearance of the jade and its firmness. Like jewel-grade diamonds, most of them have small cracks and impurities under high-magnification magnifiers, which are rare in the United States. When purchasing leather dice jade: 1. heavy leather color; 2 heavy jade; 3 heavy process; 4 heavy material shape.
Although Hetian Meiyu is produced in the Kunlun Mountains, known as the "ancestor of Wanshan", it is famous both at home and abroad. With the improvement of people's living standards, the high-end jade articles played by the aristocrats of the past have gradually entered the homes of ordinary people. Buying jade articles is an ideal choice for investment preservation. In recent years, the production of Hetian jade in Qiemo County of Xinjiang accounts for more than 70% of the output of Hetian jade in Xinjiang. The main jade species are Hetian jade white jade, green white jade, sapphire, topaz, jade, jasper, etc., processed Hetian jade jade (jade carving) ) is exported to domestic and foreign markets. Chongyu and Aiyu are the traditions of the oriental people, and the demand for jade articles is on the rise. With the expansion of the jade team, the popularity of jade articles has led to an increase in prices, and it has also provided investment opportunities for jade collectors in time and space.
1. Xinjiang Hetian jade is not white, nor transparent! This is because Hetian jade has a high content of amphibole, which is composed of a variety of minerals! Other jade species in nature are more transparent than Hetian jade.
2. After playing in the hands for 20 minutes, Hetian jade has a strong oily hand.
3. Hetian Yu's cleavage, that is, the cracks people say, will heal in the play.
4. In the process of playing or wearing Hetian jade, the jade will turn green and white, and become more and more beautiful! The skin color of the seed material will become more and more beautiful.
Look at gloss, color, transparency
luster. Gloss is the ability of jade to reflect light. Hetian jade is a grease luster - waxy luster. "Warm and zeal" is the gloss with a strong oily, moisturizing feeling. This kind of luster is very soft and makes people look very comfortable. From the overall situation, Hetian jade is stronger than other jade's "oil", which is a key point to identify Hetian jade.
colour. Hetian jade is rich in shades, including four basic colors such as white, cyan, yellow, and black, as well as transition colors such as blue-white, gray-white, and so on. In addition, Hetian jade has a lot of skin color, and the skin color can be used to make a pretty jade.
transparency. Transparency is the degree to which jade allows visible light to pass through. Hetianyu's transparency is between micro-transparent and translucent. On the whole, Hetian jade transparency (or “water headâ€) is superior to Dushan jade, and is inferior to Qinghai jade.
Second take: feel the weight and heat in your hand
weight. Hetian jade has a density of 2.93 to 3.13, which is larger than the density of ordinary jade. He has a crushing hand in Hetian jade. Different varieties have slight differences. Generally, the density of Hetian Qingyu is relatively large, and the density of white jade and ink jade is small.
heat. Thermal conductivity is the ability of a substance to conduct heat. Any material with high thermal conductivity can transfer heat quickly. When you touch Hetian jade by hand, there will be a feeling of coldness, because Hetian jade can quickly transfer the heat from his hand.
Three tests: scoring test hardness with a knife
Hardness is one of the important signs for identifying Hetian jade. The jade with high hardness has good polishing properties, which makes the jade bright and easy to store. Hetian jade has a Mohs hardness of 6 to 7, which is greater than the hardness of ordinary jade. Use a small iron knife (or steel knife) to score Hetian jade, the jade body is not damaged. It is also possible to use Hetian jade to sculpt ordinary glass, scratches on the glass, and Hetian jade has no damage, which is impossible for most other types of jade. Dushan jade hardness is also very large, but Dushan jade color is more mixed, often in a jade with a variety of colors, and low transparency, easy to distinguish from Hetian jade. The hardness of Qinghai jade is about 0.5 degree lower than that of Hetian jade. It is scored by the corners of the single-sided blade with the broken blade, which will have a slight scratch. This is a reliable method for Hetian jade and Qinghai jade respectively.
Hetian jade has a high hardness and a strong toughness. Hetian jade can draw glass without damage. For other jade, only water stone can be scratched without damage. The water stone is often used to pretend to be the best sheep fat jade in Hetian jade. The sheep fat jade is the white color of the sheep fat, the water stone is the pale color; the sheep fat jade is the grease luster, the water stone is dry and the gloss is not good. Hetian jade's structure is cotton-like. If you can't draw glass, you should carefully distinguish their color and internal structure, and make more comparisons.
