How to identify Hetian jade? How to identify Hetian jade

How to identify the real and fake Hetian jade.

1. Measure hardness.

The hardness of Hetian jade is around the right, and a knife will generally not leave traces on it, but if it is glass and jade with low hardness, it will leave traces. Buying jade can be tested at the corners, and it is not recommended that the finished product is easy to damage the jade.

2. Look at the oiliness of the jade.

There is a saying in the industry: jade looks at the seed, and Hetian jade picks run. Moist means that the color of jade is subtle and introverted, the white is not dry, the green is not bright, and there is a sense of oil.

This is all based on experience, look at the real thing, see more and have this feeling. When looking at jade, you must avoid looking at it in strong light, so as not to affect the visual experience.

3. Observe whether it is translucent and Tianyu is translucent, which can transmit light under the light, but cannot see the opposite object clearly. Aim the jade at the light source and shake it behind the jade with your hand, and really Hetian Yu can see that there is a black shadow shaking. However, this identification method is only suitable for small pieces, and the thickness of large pieces is large, which affects the light transmission effect.

4. Listen to its voice to distinguish.

Hetian jade because of the thick and warm quality, the veins are dense, so the sound is crisp and loud under the percussion, you can take two pieces of the same jade to knock a few times, if the voice is dumb is not Hetian jade, the sound of Hetian jade is more crisp, pay attention to the best not to hold the jade with your hands, affect the sound effect, it is best to hang with a rope and hit with a metal rod.

5. Check its certificate number.

Hetian jade** is more expensive, generally has a certificate, you can call the Quality Supervision Bureau** or go online to check whether the number is true.

6. Test cold and warm.

Due to its high density and poor thermal conductivity, Hetian jade can be slightly exposed to the sun or slightly heated with a hand warmer bag to see the thermal conductivity, but this method is too limited, and it takes many times to be very experienced in order to use this method to identify.

Hetian jade is of excellent quality and well-known at home and abroad. In recent years, with the soaring price of Hetian jade, the Hetian jade collection team has been growing. Through contact and communication with some jade carving masters, a set of simple and practical identification methods can be used as a reference for Hetian jade collectors.

One look: look at the gloss, color, transparency.

Luster. Luster is the ability of jade to reflect light. Hetian jade luster belongs to the oil luster - waxy luster.

"Warm and luster" means that the luster has a strong oiliness and a moisturizing feeling. This luster is soft and pleasant to look at. From the overall situation, Hetian jade is stronger than other jade, which is a key point in identifying Hetian jade.

Color. The hues of Hetian jade are relatively rich, with 4 basic tones such as white, cyan, yellow, and black, as well as some transitional colors, such as blue-white, off-white, and so on. In addition, there are many skin colors of Hetian jade, and the use of skin color can be used to make beautiful jade.

Transparency. Transparency is the degree to which jade allows visible light to pass through, and the transparency of Hetian jade is between slightly transparent and translucent

or "Shuitou") is superior to Dushan jade, but inferior to Qinghai jade.

Second, take it: feel the weight and heat in your hand.

Weight. The density of Hetian jade is larger, which is greater than that of ordinary jade, and there is a feeling of pressure when holding Hetian jade in your hand. There are slight differences between different varieties, generally Hetian green jade has a higher density, and white jade and black jade have less density.

Heat. Thermal conductivity is the ability of a substance to conduct heat. Any material with strong thermal conductivity can transfer heat quickly. When you touch Hetian jade with your hand, you will have a cold sensation because Hetian jade can quickly spread the heat from your hand.

Three tests: use a knife to cut and test the hardness.

Hardness is one of the important signs for identifying Hetian jade. Jade with high hardness has good polishability, which can make jade shiny and easy to preserve. The hardness of Hetian jade is 6 to 7 on the Mohs scale, which is somewhat greater than that of ordinary jade.

Use a small iron knife (or steel knife) to carve Hetian jade, and the jade body is not damaged. It is also possible to use Hetian jade to carve ordinary glass, and the glass is scratched, while Hetian jade is not damaged, which is not possible with most other types of jade. The hardness of Dushan jade is also very large, but the color of Dushan jade is more mixed, often there are multiple colors on a piece of jade, and the transparency is low, which is easy to distinguish from Hetian jade.

The hardness of Qinghai jade is about lower than that of Hetian jade, and the edges and corners of the single-sided blade of the broken blade are cut, and there will be slight scratch marks. This is a reliable way to distinguish between Hetian jade and Qinghai jade.

Now the real and fake connoisseurs can't tell the difference, and the Russian material is fake.

Bai is already difficult to distinguish, the country du

The supervision agency does not need to go to dao at all, he only supervises the density and refractive index, and now Hetian jade refers to a concept in a broad sense, Russian material, Qinghai material, which is similar to the density of Hetian jade, are all supervised as Hetian jade. (In fact, the real supervision of these 3 materials is hardness and oiliness.) And these can only be distinguished by experience.

And the hardness you don't carve yourself definitely don't know, and the oiliness is now polished after oiling you can't identify, the naked eye is not an expert, how to teach you you you will not understand.

Now I can guarantee that more than 90% of the market is not Hetian jade, let alone Hetian seeds.

1. Use a knife to test its hardness, Hetian jade Mohs hardness reaches about it, take a knife to scratch it on it generally will not leave traces, if it is glass and jade with low hardness, it will leave traces, but now many imitation materials also choose some jade with high hardness, which will also leave no traces.

2. Check the color of Hetian jade, Hetian jade only has four major colors: white, cyan, ink, and yellow, and there is a red one in the legend, but it has never been seen, so if you meet a red Hetian jade, it is designated as a fake. The color of white varies from white to bluish-white, yellow from pale yellow to dark yellow (including sugar), cyan from pale cyan to dark cyan, and ink from ink to pale black.

3. The value of mutton fat color and yellow Hetian jade is higher, the texture of mutton fat jade is delicate, white as clotted fat, it is the best variety of white Hetian jade, only Xinjiang has this variety in the world, because the yield is very rare, so it is extremely precious. In addition, topaz is also very rare, second only to sheep fat jade in value. The value of cyan Hetian jade is the lowest, and the color distribution of cyan Hetian jade is from light cyan to dark cyan, with many types and different shades of color, which is the most common type of color in Hetian jade, so it is slightly lower than other colors.

4. Observe whether it is translucent, there are three kinds of transparent, translucent and opaque in jade, and Hetian jade is translucent, under the light, it can pass through the light, but it is not clear to see the image of the transmitted object. You can point the jade at the light source and shake it behind the jade with your hand, and you can really see that there is a black shadow shaking.

5. Listen to its voice to distinguish, Hetian jade because of its thick and warm quality, dense vein, so the sound is crisp and loud under the percussion, you can take two pieces of the same jade to knock a few times, if the voice is dumb, it is not Hetian jade, and the sound of Hetian jade is relatively crisp, like steel.

6. Weigh the weight by hand, when buying, you can weigh the same volume of jade by hand, Hetian jade is heavier, solid and thicker, and generally heavier than other jade.

7. Check its texture, Hetian jade texture is moisturizing, delicate and soft, and the surface has oil luster, and the moisturization and oil luster of other jade are not as good as Hetian jade. In addition, you can put jade on the **, there will be a cool feeling, and glass products are not.

8. Check its certificate number, Hetian jade ** is more expensive, generally has a certificate, you can call the Quality Supervision Bureau** or go online to check whether the number is true.

Nephrite is a type of nephrite jade (commonly known as **jade), and it is also a high-end nephrite jade in China, with a leading brand [1]. Hetian jade is divided into "narrow sense" and "broad sense". "Narrow sense" (traditional concept) refers to jade produced in Hotan, Xinjiang, which is famous for its "purple material".

So as such an expensive jewelry, how to distinguish the authenticity of Hetian jade? Let me explain it to you in detail. How to distinguish the authenticity of Hetian jade by yourself?

Method Step 1Sensory Identification:1.

Luster, Hetian jade luster is mostly oily or waxy, giving people a feeling like solidified fat, very textured. 2.Structure:

Hetian jade has fine particles and a fine structure, mostly felt-like and velvet-like structures with interwoven fibers. Some jade materials are better than others, and the structure in the jade cannot even be observed. 3.

Transparency, Hetian jade is mostly translucent to opaque, mostly slightly transparent, relatively poor in gemstones and jade, but on the other hand, the transparency is not high, jade is more thick and stable, so the identification of transparency needs to be considered in combination with other factors. More detailed identification methods: a:

Look at the material of the jade. Material is the primary premise of jadeite collection, and high-quality jadeite is very important for a piece of jadeite. Usually the same grade of jade** is 6-8 times that of mountain material.

In the market or on the Internet, it is more common to sell skinless mountain materials or Russian materials, which are all field materials. If you use Russian materials as materials to sell Tianzi, it is difficult for people with less experience to distinguish, and there are only a few on the market or on the Internet. There is no national standard for real sheep fat jade, and it is produced in ice-covered glaciers.

White as mutton fat, mutton fat jade is not only white, but also never green, the oil content is extremely high, not the color of the mutton fat level of mountain material or Ziyu comparable. Some veteran players have been playing jade for decades. The difficulty and rarity of mutton fat jade make it difficult for people who love jade to find mutton fat jade and it is difficult to ascend to the sky.

It can be said that even if you have money, you may not be able to buy the best product, mutton fat jade.

Hetian jade is mainly identified by density and refractive index.

The density of Hetian jade is in grams of cubic centimeters, the refractive index is in, and it can also be recognized in combination with structure and shell features.

Answer the method of buying Hetian jade: look at the material of jade, identify the shape and carving, analyze the craftsmanship and fine art, and try to buy skin color jade and sound. 1. Look at the material of jade and the material of Tianyu is often proportional to **, the higher the material, the higher the **, and the greater the appreciation space.

The Hetian jade material on the market is often mixed with mountain material or Russian material, and its ** is often less than one-sixth of Hetian seed material. Hetian jade is glutinous, the color is moist, and the percussion sound is crisp and pleasant. 2. Identifying the carving of good jade is certainly first-class, and the modeling is also the most important point of jade collection value, good works are often vivid in artistic shape, harmonious and symmetrical in proportion, smooth in line, and fine in workmanship.

The surface of jade has a good polishing effect and will not appear rough. The carved pattern and the raw material are in one shape, and the state is natural. 3. The artistic value of the analysis of the fine art jade is also an important point of appreciation, a good Hetian jade is like a thousand miles, and a good carver is needed to tap the advantages of jade, and the appreciation of art is based on the excellent carver.

Carvings that can reflect the characteristics of the work are often a little more valuable than jade carvings that blindly imitate the works of ancient masters. On the basis of originality, it is rare to have a complete color, shape and rhyme. 4. Try to buy skin color jade and Tian jade in the process of oxidation often form different colors, including autumn pear, jujube red, and other colors.

The skin color of Hetian jade is also a highlight that can be added in the carving process. Using the different skin colors, it can be made into beautiful jade, which is naturally more durable than ordinary solid color jade carvings, and the value is also higher. 5. The sound of Hetian jade is thick and warm, and the vein is dense, so the sound is crisp under the percussion, and you can take two pieces of the same jade to knock a few times, if the sound is dull, it is not Hetian jade, and the sound of Hetian jade is relatively crisp and like steel.

The study of jade must be done by seeing the real thing, and it is useless to talk on paper. If you see more, you will naturally know the advantages and disadvantages, Ma Weidu once said that he could see the truth and falsehood at a glance of the things on the stall, and he couldn't say anything if he wanted him to say anything. This is all accumulated over a long period of experience.

This is also a little bit of my learning experience, I hope it will be helpful to you.

Dude, let's read a book.

You can go to Hetian Yuti Bar to learn Many folk masters there will explain it to you.
