1, real jade, warm and shiny, translucent and opaque, with cotton wool or other impurities in the jade, which is a normal phenomenon. Fake jade has no aura, its color is dry and dull, and some have bubbles in it.

2, water identification method: drop a drop of water on jade, such as dewdrop for a long time, for real jade; The water droplets disappear quickly, which is a fake.

3. Hang the jade to be identified in the air with a thread and pat it gently. Zhen Yu's voice is crisp and pleasant, soothing and far-reaching. False but not beautiful (this method is suitable for slightly thinner jade pendants).

4, touch method: real jade in your hand, it feels heavy, fake jade is lighter. In addition, if the real jade is touched by hand, it will feel cold and lubricated.

5, inspection method: jade towards light, such as sunlight, lighting, if the color is transparent, it is naturally true jade.

6, tongue licking method: the tip of the tongue licking real jade has a astringent feeling; Fake jade has no astringency.

7. Magnifier viewing: put the purchased jade under a magnifying glass to watch, mainly to see if there are cracks. The jade without cracks is the best quality, followed by cracks. Even if it is real jade, the value of cracks is greatly reduced. The more cracks, the more obvious and the lower the value.

8. Knife drawing: Real jade is hard, and no trace can be drawn with a pencil sharpener. The fake jade is soft and the knife cuts the mark. Choose the bottom or inconspicuous part of the jade when cutting. In addition, some jadeites have a hardness of 2. 2-3, so scratches may also appear, and attention should be paid to identification in actual operation.

9. Real jade articles have uneven fractures and dense material structure. The false fracture is neat and shiny, and it is a glass thing; The fracture material has a rough structure and no waxy luster. Observe carefully with a magnifying glass more than seven times, identify its edges and corners, holes, depressions and scribe lines, and you can find the clues of counterfeit goods in subtle places.

Secondly, the types of jade and ancient jade can be distinguished by the following methods:

1. Old jade and new jade can be identified from two aspects: old jade has an oxidized jade skin on its surface, commonly known as "patina", which looks like pear skin, which is obviously different from the natural color of jade, while new jade does not; Furthermore, from the perspective of the subject matter of sculpture, ancient jade is a symbol of rank and power, and there are many mythical flower and bird figures, such as dragons and phoenixes. New ones are generally auspicious.

2. Identification method combining eye observation and hand touch-there are 65,438 yuan of jade in the market, which is the same as 20 yuan's, and there are also thousands of jade worth. To this end, people can moisten it with fine jade, which is transparent and greasy, and feels moist when pinched in their hands. Through a magnifying glass or microscope, it can be seen that the jade has a fiber interwoven structure and fine particles; Artificial glass has no structure and bubbles can be seen. In addition, it can also be carved with a knife in an inconspicuous place. What can be carved must be fake jade, but what cannot be carved is real jade. Because the top grade Hetian jade is getting scarce, it can reach tens of thousands to hundreds of thousands of yuan per kilogram, while the average Qinghai white jade and Russian white jade are only a few thousand yuan per kilogram, so some people mix it with Hetian jade. The minerals of these jadeites are basically the same as those of Hetian jade, but the surface color is dark and not soft, which will become more dim after a long time.

Is jadeite real or fake? How is the fake jade made? How to tell!

Jade is true and false. There are many kinds of jade! For example, Hetian Jade and xiuyan jade, or xiuyan jade for short, are named after Xiuyan County, Liaoning Province. You want Hetian jade, you get a piece of xiuyan jade. Although they are all jade, can you say they are fake jade? It's just a different place of origin! But they are all real jade.

Fake jade is a kind of artificial fake jade, or uses low-value or worthless jade as valuable or high-value stone. For example, quartzite jade can be used as fake jade or pretend to be high-value jade after being cut, but they do belong to jade. This kind of fake jade is better, at least a piece of jade. "Jade" made of synthetic glass products or plastic products is really fake jade!

There are professional and non-professional methods to distinguish, professional is more complicated. There are many on the Internet, which need professional equipment and instruments. Non-professional ones are relatively simple, relying entirely on experience. Some feelings can only be expressed in words, and it seems amazing. I don't think it's clear!

My personal opinion is: first, it is not difficult to distinguish colors; 2. Hardness is a key index to identify jade, and it is not difficult to master it, such as small iron knives, copper keys, pointed glass pieces, etc. ; Third, high-concentration flashlights; Fourth, I have seen the types of contact stones and accumulated practical experience; Basically, it can be identified! As for the more complicated ones, such as wisps, collaterals and collapsibility, as long as the specific problems are treated specifically!

How to tell the true and false jadeite?

This is to see if it is true or not. This is a relatively simple method to identify true and false!

1; I just put jade on my face and felt very cold. If it doesn't get cold for two or three seconds, it means it's true. Because jadeite can transfer heat and dissipate heat quickly! If it is not cold on the face, it is fake.

2; That is, the magnifying glass should be 10 or 30 times to look at the crystals inside to see if there are any small cracks like cobwebs, and whether the color is on the cracks or on the jade surface. If there is, it is fake. Hetian jade looks like rice paste, because the crystal is fine and the color is even. Jade looks like the wings of a fly, some like a little ofloxacin, and some like broken glass. Because the jadeite crystal is not delicate enough, there are many colors on the same jadeite.

3; It's an appraisal of destruction. Set it on fire. It's just burnt black, burnt yellow and stinky. Black and yellow are fake if they are not washed off. It's burnt and smelly. That's even more fake. Really, when the fire comes, there will be small water droplets attached to the jade surface, which will burn black and return to its original color after washing. But we generally don't use this method, which is not good for jade.

Just look at the delicacy of jade. What is exquisiteness? Fine is the crystal of jade, and the size of the crystal depends on the quality of jade. The smaller the crystal, the better, and vice versa. Crystal is the internal structure of jade, with small crystals in the form of columns and crosses, that is, you shine a lamp on the jade to see if there are snowflakes and the like. The bigger the snowflake, the worse it is. Look at the quality and quality of jade!

2. Look at transparency. Transparency is also important. The best jade is not as transparent as glass. It feels good to be like ice. The more opaque it is.

3 Look at the color. The color of jadeite is green, followed by purple, yellow, black and melon skin green. Hetian jade is white, and white like sheep fat is the best, followed by yellow, blue, black and sugar.

How to tell the truth of a jade pendant?

Kuba helps the assistant answer your question about "". Look, mainly depends on the crystal transparency, real jade has strong transparency and oily luster; Listen, Zhen Yu's voice is crisp, but her voice is dull; In the test, the real jade scratched the glass, but the jade itself was intact. Common fake jade includes plastic, stained glass, marble, electrochromic fake jade made of jade powder and crystal with salt water, imitation jade containing nitrate, etc. And their identification methods are different. Plastic is lighter than jade, and its hardness is poor, so it is generally easy to identify. It's easy to distinguish between painting and getting off work. As long as you take it under the light or check it in the sun, you will see many bubbles in the glass. It is difficult to distinguish fake jade by electric color. Its purpose is to electroplate inferior jade and then coat it with a beautiful emerald appearance, so it is easy to mistake it for real jade. At this time, you need to observe carefully. If there are some small cracks with blue in the green, it is fake jade. Because electroplating will leave cracks, experts call it "spider claws". It is also said that if the electro-colored fake jade is put in hot oil, the electroplating color will fade and return to its original color. Synthetic jade made of jade powder, crystal and salt water is an imitation dark old pit jade. The identification method is simple, that is, their specific gravity is different. The specific gravity of natural jade is 3.3-3.4, while that of synthetic jade is only 2.8. Weigh by hand, or weigh by balance to distinguish between true and false. Jade imitated with nitrate looks whiter and smoother than jade. The ancients said, "Jade is better than salt, so it must be high." That is, white jade should be as advanced as nitrate. It can be seen that nitrate and jade are difficult to distinguish. However, the facts are different after all. As far as color is concerned, white jade is often blue, and white is rare, while nitrate is pure white. As far as jade is concerned, jade is moist and delicate, as fat as cream. Nitrate is wet, but there are thieves in it. White jade is a natural product, and it is difficult to have a unified structure, including jade ribs and jade flowers. If nitrates are manufactured artificially, there is no such appearance. White jade has a solid texture and no bubbles can be found. No matter how well nitrate is treated, bubbles and pores are often exposed. If you know these items, you won't regard nitrate products as jade articles.

How to tell the true and false jadeite?

Teach you a simple method:

1, looking at the sunshine, there are some foggy things in jade, like cotton wool.

2. Jade is very hard, like a diamond, so you can draw a series of marks on the glass.

3, the jade is cold, put a head on the jade, burn it with a lighter, and have a fever next to the jade head.

Classification of jade:

Jade can be divided into nephrite and jadeite, which are two different minerals. The colors of nephrite are translucent white, yellow, green and black, and the colors are evenly distributed. As for jadeite, there are mainly white, purple, yellow and green, and the uniformity of color distribution among different germplasm will be different.

The vast majority of jades produced in China are nephrite, and "sheep fat white jade" is a treasure in nephrite, with delicate texture and white color. Many exquisite jade works of art are carved from nephrite.

Jadeite is mainly produced in Myanmar and is even rarer than nephrite. Because jade is superior to nephrite in quality, color and price, jade ornaments on the market are mainly jade, and the demand of consumers is very great, so we focus on jadeite.

Appreciate jade:

The appreciation of jadeite should pay attention to color and germplasm, which can be subdivided into color, transparency, clarity, cutting and cracking, generally starting with its color.

colour

Color is the most important factor affecting the value of jadeite, and the color of jadeite can be evaluated from the following four areas:

Purity: Purity refers to the ratio of primary color to secondary color of jadeite. Take green jadeite as an example, pure green is the best, followed by yellow or blue, and gray is the worst.

Appropriate shade: when it comes to the depth of color, of course, the thicker the better. But if the color is too thick, it will have the opposite effect and reduce the quality of jade.

Be bright: the brighter the color of jade, the more attractive it is. The more gray or black it contains, the darker the color.

Uniform: The more uniform the color distribution, the better, and the higher the value.

transparency

The transparency of jadeite affects the refraction of light, thus affecting the overall aesthetic feeling. When the light enters the transparent and delicate jade, it will reflect beautiful light, which will make people feel the crystal clear of jade and greatly increase its aesthetic feeling. On the contrary, if light meets jadeite with low transparency and rough texture, it will reflect dark light, which will greatly reduce the attractiveness of jadeite.

clean

Cleanliness refers to the defects contained in jadeite, mainly white and black, which are caused by other minerals contained in jadeite. Relatively speaking, black defects are more ugly than white ones. The less impurities in jadeite, the better.

incision

The processing of jadeite products can be divided into two categories: light body and carving. Because the surface of the bare finished product is not covered, the requirements for raw materials are high. In addition to no cracks, the proportion of cutting work, the thickness of the product and whether it is symmetrical are also very important, which can affect the appearance of the finished jade. For example, the sliced "egg noodles" should not be too thick or too thin, and the position of the "pot" should be in the middle and the proportion should be moderate.

The evaluation of flowers mainly measures their aesthetic feeling and the fineness of carving. Usually jadeite with cracks will be carved to cover up its defects.

crack

Cracks will greatly reduce the value of jadeite. If there is a crack in the jade jewelry, it may crack along the crack if it is slightly collided. Therefore, you need to be extra careful when buying jade ornaments. Generally speaking, with a flashlight, it is easy to detect the existence of cracks.

High-quality jadeite can be sold at a considerable price, but the supply in the market is limited. In order to get better profits, some businessmen do not hesitate to manually treat jadeite. So commodities A, B and C appeared in the market.

Artificial jadeite

C goods

C goods refer to fake colored jade that has been artificially colored. The method is to infiltrate the dye into the colorless jadeite at high temperature and high pressure, so that all or part of it is dyed into emerald green or purple, but its color will fade and become dim with time.

Class b goods

B refers to the chemical removal of jadeite with defects, impurities and yellow parts on the surface, leaving only the original green and white elements, and then injecting epoxy resin glue into jadeite as consolidation, so that the whole jadeite looks more transparent and the color is more vivid. Because the interior of jade has been destroyed in the process of chemical treatment, the structure has become loose, so B goods are prone to cracks on the surface. In addition, if dyes are added during the treatment, it is called B+C goods.

natural jadeite

A goods

A goods refer to natural jadeite that has not been artificially treated at all.

In the long-term practice of jade processing and production, the predecessors of China's jewelry industry have summarized a lot of experience about jade, and expressed these characteristics of jade in the form of concise aphorisms. ......

How to distinguish the authenticity of jade by the simplest method?

In view of its authenticity, we can observe it from three aspects: first, because glass is very brittle and hard, its structure is loose, and it lacks the density and toughness of jade, and it can't stand strong high-speed rotary carving. Therefore, high relief and round carving generally cannot be processed on glass. Second, use a magnifying glass to find bubbles, even if you can only see one, that is, glass. Third, chromium oxide is added to the glass, and the color is close to ruby; Adding cobalt oxide, the color is close to sapphire; Adding chromium oxide and copper oxide, the color is close to emerald. There are many colors. However, its color tone is always relatively thin, lacking the oily and rich feeling of natural jade color. The more difficult varieties are mainly fake jade made of polymer materials. Its color can be adjusted at will, and it is difficult to find bubbles under a magnifying glass. It is said that the original appearance can be displayed on the infrared spectrometer, but the key to visual inspection is to see whether there are natural stone lines on the surface of the instrument, in addition to the general unrealistic destructive inspection, cracking to find the stone section, burning to see its reaction. After all, manual processing is unnatural and will be exposed under a magnifying glass. The identification of jadeite can be divided into two categories: new jade and old jade. The identification of new jade focuses on the authenticity of the variety, the quality of the texture and the fineness of the sculptor. Some technical contents have been talked about before. However, the identification of Lao Yu is unusual. In addition to several basic requirements, new jade also needs to know the production age and historical value of jade. The confirmation of the historical value of jade is based on a clear era. Familiar with the common shapes, characteristic crafts and popular colors of jade in different times. Then refer to the papers on the characteristics of jade in a certain era, and get in touch with each other, and your jade dating level will be rationally improved. At this time, you should contact the real thing as much as possible and correct the parallax between the picture and the real thing in the book. In addition, the judgment of the times allows a certain span on some jade articles. Because jade tools are precious and not perishable, as a family heirloom, early jade appeared in tombs hundreds of years later, and there are many precedents. The late period of the last era and the early period of the next era are not completely unified in style. Jade has no date, and subtle differences are normal.

How to tell the true and false jadeite?

Jade can be divided into nephrite and jadeite, also known as jadeite. From the chemical composition, nephrite is a silicate containing calcium, magnesium and iron, while jadeite is a silicate containing sodium and aluminum.

Here are several common methods to identify true and false jade articles:

Identification method of (1) water

Drop a drop of water on the jade. If it becomes dew, it will be real jade if it persists for a long time.

(2) Touch by hand

If it is real jade, it feels cold and lubricated by hand.

(3) Observation method

Looking at jade under the light, it is a real jade with clear color and even green distribution.

(4) tip identification method

The real jade on the tip of the tongue is astringent, but the fake jade is not.

In addition, you can also observe with a magnifying glass, mainly to see if there are cracks, and the value of cracks is greatly reduced.

Jade quality appraisal

There are six criteria to identify the quality of jade, namely "color, transparency, uniformity, shape, percussion and luster".

(1) color

Green is the best jade, and the value of red and purple jade is only 1/5 of green jade. If jade contains red, purple, green and white, it is called "Fulu Xi Shou"; If it only contains red, green and white, it is "Fu Lushou". The dull and yellow ones are inferior. If it is monochrome jade, the color is better.

(2) Pass

Transparent and crystal clear as glass, no dirty spots, no chaff and no astringency is the top grade. Translucent and opaque jade are called intermediate jade and ordinary jade respectively. Before and during the Qing Dynasty, jade with red, green and white colors was called jadeite. In modern times, jadeite refers to generally transparent jade. At present, jadeite is transparent and green.

(3) uniforms

The color of jade is uniform. Although it contains white and green, the color is uneven, so the value is very low.

(4) Shape

The shape of jade can be processed into different styles according to different aesthetic requirements, and there is no special standard. Generally speaking, the bigger the jade, the better.

(5) Knock on the door

Jadeite often has cracks and cuts, which are generally not easy to observe. If you knock with a metal bar or gently throw jade on the counter, you can tell whether there is a crack from the clear voice. The louder, the better.

(6) according to

Emerald has black spots and flaws that are not easy to find with the naked eye. As long as you take pictures with a magnifying glass of 10 times, you can have a panoramic view.

The quality of jade can be divided into 10 grades, and each grade can be subdivided into three grades: upper, middle and lower. Among them, white jade has the lowest value regardless of color and transparency.

Natural jadeite is characterized by slight light color, without light blue (commonly known as evil color). There is also a synthetic jade, which is made of jade powder, crystal and salt water, and looks like a dark "old pit jade". The identification method is very simple, because it is different from natural jade in proportion. It can be said by hand or with a balance, and the heaviest one is the real jade.

At present, some exquisite fake jade is often mixed in the market. The general methods to identify fake jade are watching, listening and testing.

(1) Look

Mainly depends on the crystal transparency, internal structure, luster and so on. Real jade is transparent, oily and shiny, with natural patterns, and the internal fiber state is not easy to imitate.

2. Listen

Real jade sounds crisp, while fake jade sounds dull.

(3) measurement

Mainly to measure hardness. With the glass plate (friction hardness of 5.5) as the standard, except jadeite and turquoise, stripes can generally be drawn on the glass plate, and jadeite itself is complete. Fake jade is generally soft and can't scrape the glass.

Common fake jade is generally made of plastic and glass. They are all amorphous materials with low hardness and low density, and they are also the essential characteristics of materials. Plastic, for example, can be picked with a steel needle or floated gently in your hand. Glass is bubble-like under light or sunlight, and amorphous under polarizer (there is no periodic change of light and shade when rotating), and there are raw materials for making spiral stripes.

Quality identification of jadeite jade

Among many members of the jade family, jade is the most precious. It is a natural ore with extremely high hardness and little output. Its colors are mainly green and red. Red is scarlet and green is emerald, hence the name jade.

Classification of (1) jadeite

(1) Super grade: bright green (emerald), apple green, glass floor (translucent, fine texture), even and bright, without impurities and cracks.

Commodity grade: green, oily green land, slightly transparent, translucent grandmother green veinlets and mottled green.

③ Ordinary grade: lotus root powder mill, bean green, light green, fine white and slightly transparent. Opaque jadeite is generally only used as jade ornaments.

(2) Quality identification of jadeite jade

1 texture. Natural jadeite is transparent or translucent. ......

Ordinary people use relatively simple methods to distinguish the authenticity of jade.

Generally speaking, because of long-term immersion and erosion by water, seed jade is delicate, waxy, translucent, with few diaphragm lines and high density; The mountain material is dry, japonica-shaped, opaque and has more diaphragm lines, which is caused by explosive explosion. However, although the old pit in the mountain material is not as good as the seed jade, it is relatively good. Therefore, the quality of nephrite is related to its pit mouth, and the old pit jade is the best, followed by the old pit mountain material and the new pit mountain material There is a saying in the industry that there are three ways to identify nephrite, that is, look at the following three aspects with a pair of eyes: 1, and look at the texture, which is the most important factor in identifying nephrite. Texture means that the body is like coagulated fat, clean and inclusive, thick and moist, and the pulse is solid and dense. This is the specific standard of good nephrite. On the other hand, if the texture is thick and dry, there is no luster in it, and the appearance is not delicate and moist, it is inferior jade. 2, look at the color nephrite because of different colors, there are white jade, topaz, sapphire, jade, generally speaking, in the case of the same or similar texture, white jade is expensive, topaz is second, sapphire and sapphire are of low value. Color is one of the criteria for judging nephrite. Even white jade depends on the degree and purity of white. If it is blue in white or gray in white, it will affect the value of jade. Look at the so-called jade carving by the sculptor. Sculptors are of great significance to nephrite. Generally, sculptors mainly look at three aspects: first, the old and new works, the longer the age, the higher the value; The second is to look at the content of the work, in which the value of auspicious patterns is not common; The third is to look at the fineness of the work. The more meticulous the work, the higher the natural value. In addition to the above three elements of texture, color and carving, other dimensions and appearance are also one of the criteria for identifying the quality and value of nephrite products. Second, the identification of nephrite authenticity: 1, nephrite and jadeite identification: Jade is often regarded as old nephrite because of its fine texture, full head and waxy to oily luster. However, jade is soft and easy to eat with a knife. Carve a few times with an ordinary knife. It is jade that eats the knife, but nephrite that doesn't enter the knife. If you don't have a knife, you only need to look at the place where the knife is cut when carving. Nephrite won't be hairy when it is cut, but Xiuyu does. In addition, jade feels light, and its sound is dull and dumb when struck, unlike nephrite. In addition to Xiuyan jade, there are other ordinary jade posing as nephrite, and its identification method is roughly as above. 2. The distinction between Hetian jade and Russian jade and Qinghai jade: Qinghai jade and Russian jade are estimated to be produced by Tianshan branch, so the ore composition is similar. This kind of jade is mostly white and looks like waxy grease, so it is easy to pass off as white jade. Moreover, its hardness is the same as that of white jade, and it can't be identified by eating a knife. However, this kind of jade has high timely content, so compared with white jade, it is rough, astringent, brittle and transparent. Often exposed to the sun and rain, it is easy to get diaphragm, crack and change color. Especially nephrite and Russian jade are compared together, one is waxy and the other is japonica; One nourishes in vain and the other dies in vain. The difference between them is self-evident. At the same time, it is not difficult to distinguish crisp sound from dull sound when knocking at the door. Hetian jade is a kind of aura, symbolizing great wealth, but people often lack the vision to distinguish authenticity. With the improvement of people's living standards, high-grade jade, once played by princes and nobles, has gradually entered the homes of ordinary people. So, where does the collection of Hetian jade ware begin? How can I buy real Hetian jade products? One: Look at the material of jade: the material is the primary premise of jade collection, and high-quality jade material is very important for a jade. At present, the usual price, the same level of jadeite is 6-8 times that of mountain material. In the market or online, it is more common to sell skinless mountain materials or Russian materials as fillers. Russian material is also a mountain material, and the material composition is the same. It is called Russian material because the ore is mined in Russia and the price is much lower. It is characterized by white color, but the jade is too watery, that is, the transparency is too heavy, and the density and oil texture are not as good as the authentic Hetian jade! It is difficult for people with little experience to tell if they sell rice in Russian. At present, there are only a few on the market or online. Real suet jade, there is no national standard at present, produced in frozen glaciers. Sheep fat jade is as white as sheep fat, which is not only white but also never turns green. It has a high degree of grease and is comparable to jade with unusual mountain material or sheep fat color. Some old players have been playing with jade for decades. The rarity and rarity of sheep fat jade ... how to distinguish the types and authenticity of jade?
