How to judge the authenticity of jade?
Question 1: How to distinguish the authenticity of jade? 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 visual inspection and hand touch ―― At present, there are 65,438 yuan and a piece of jade in 20 yuan, and there are also thousands of jade worth. To this end, people can moisten it with fine jade, which is transparent, greasy and moist in their hands. Through a magnifying glass or microscope, it can be seen that 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.

Question 2: How to distinguish real jade from fake jade? Simple methods are just some simple methods, and it is best to go to the appraisal department for testing.

Identification of true and false jade articles

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 method of inlay is very simple, because its specific gravity is different from that of natural jade, and it can be weighed by hand or by balance, and the most important thing is 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.

Question 3: How to distinguish between true and false jadeite? The reliable methods to identify true and false jadeites are: seeing, listening and testing. 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. Chinese website /...ID=278 How to buy jade articles There are many kinds of jade articles in China with a long history. According to the origin, the famous ones are Nanguo Jade produced in Xinyi, Guangdong, Henan Jade produced in Henan, Shandong Jade produced in Shandong, and Sheep Fat Jade produced in Yili and Hotan, Xinjiang. Most of the more expensive jade jewelry is made of these jades. Distinguishing the quality of jade mainly depends on whether its color has five characteristics: thick (rich), bright (bright), beautiful (beautiful in color), positive (pure) and soft. If it basically matches, it is the top grade, that is, the beautiful jade. If jade looks pale (dull), muddy (dull), old (dark in color), flowery (impure) and oblique (incongruous), it is inferior. When buying jade articles, don't choose them under strong light. Because the light irradiation is easy to make jade lose its original color, it often covers up some flaws and confuses the real with the fake. In addition, we must learn to distinguish the authenticity of jade. At present, there are many kinds of fake jade on the market, including plastic, glass, marble, electric color and so on. Plastic and marble are lighter and harder than jade. There are some bubbles in stained glass, which will be found if you check them with light or sunlight. Electro-colored fake jade is difficult to identify. It is a beautiful and dazzling turquoise appearance painted on inferior jade. At first glance, it is not much different from real jade. If you look closely, you may find that it often has some "spider claws" (small cracks with blue in green).

Question 4: How can we identify the authenticity of jade? What kind of jade is good jade? Jade in China can be divided into nephrite and jadeite.

Emerald, commonly known as "Emerald" in China, is a rising star in traditional jade in China, and also the top grade in all modern jade. Common jadeite colors are white, gray, pink, light brown, green, emerald green, yellow-green, purple and so on. Most of them are opaque, partly translucent and glassy. According to color and texture, there are more than 20 varieties, such as ruby green, brilliant green, yellow sun green, sunny green, glass green, Ying Ge green, spinach green, shallow water green, light sun green, frog green, melon skin green, plum blossom green, blue-green, gray green, oil green, violet, lotus root powder land and so on.

Nephrite is called real jade, such as white jade, sapphire, clear white jade, jasper, jet and so on. All have waxy luster, pure milky white. Judging from the jade articles of past dynasties, nephrite is the main jade used in China, and ancient nephrite is called traditional jade in China. The common colors of nephrite are white, gray, green, dark green, yellow and black. Most nephrite are opaque, and some nephrite are translucent and glassy. The varieties of nephrite are mainly divided according to different colors. The best white jade is as white as suet jade, which means that the floating sapphire of suet jade is gray to bluish white. At present, some people call gray sapphire blue white jade. Jasper is green or dark green, and sometimes black spots can be seen, which is caused by impurities such as chrome spinel minerals. Containing many impurities, when it is black, it is a precious jet. Topaz is also a precious variety. Sapphire has a yellow shell with sugar water, which is called "sugar jade" by the existing people, "pink jade" by some people when the white is slightly pink, and "tiger jade" by some people when the tiger skin is colored.

People who play jade for the first time are most afraid of encountering fakes because they don't understand jade. At present, the identification of glass imitation jade products on the market is probably the most common and simple one among fakes. Common ones are bare small rings, chicken hearts and jade pieces called "emeralds". Because this kind of glass product is made by casting mold, the high-temperature glass liquid will overflow a little at the edge of the object when it is combined, and it will become a vaguely convex mold line after cooling. Touch it with your hand, and your eyes will find something. If you look at the light with a magnifying glass, there must be large and small bubbles inside.

If experts are not invited, people who use jade for the first time should identify the authenticity of jade by themselves, which can be observed from three aspects:

1. Because the texture of glass is very brittle and hard, the structure is clearly arranged, and it lacks the density and toughness of jade, so it can't stand strong and high-speed rotary carving, so it is generally impossible to process high relief and round carving on glass.

Second, use a magnifying glass to find bubbles, even if you can only see one, you can confirm that it is not jade.

Thirdly, chromium oxide is added into 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 ... and so on, there are many kinds of fake jade. However, their colors are always relatively thin, lacking the oily and rich feeling of natural jade color.

The identification of new jade and old jade is different. The identification of new jade focuses on the authenticity of the variety, the quality of the texture and the fineness of the sculptor. The identification of old jade is relatively complicated. In addition to several basic requirements, new jade also needs to identify its production and historical value.

Question 5: How to distinguish the authenticity of jade? Distinguishing between true and false is to distinguish between true and false in ancient jade, which is the primary stage of distinguishing ancient jade, not a higher level of dating. Can be carried out according to the following steps:

1. Jade products:

1. Official ancient jade: pure white jade, sapphire and jasper are mostly used. The official imitation has a jade source.

2. Ancient jade imitation: pure sapphires and jasper were mostly used. At that time, jade workshops could still get such jade materials, and they would not use poor quality jade materials to meet the needs of dignitaries in society. The remaining corner jade will be made into small pendants to meet the needs of civilians.

3. Modern high imitation jade: the source of jade is exhausted, especially the old jade is harder to find. How to solve the material? A: Reorganized with scraps of ancient jade. B: Xinjiang Jasper, gobi jade, Qinghai Jade, Northeast Yellow Jade, Hemo Jade (yellow seed material), dushan jade (Nanyang Jade has two producing areas), serpentine (xiuyan jade has 13 producing areas), Han Guoyu, Russian jade, etc., which are newly mined, with good quality, no blemishes and no stone inclusions. Early synthetic jade materials are also mixed in it. Most of them can reach a hardness of 5.5-6. The polished jade is very smooth and easily recognized by buyers.

4. Modern folk ancient jade: occupy the market at a low price. A: Generally, high imitation jade with slightly higher price is not used, but low-priced variegated jade, variegated jade with many spots or inferior jade with heavy stones are used. Unfortunately, it helped mottled and stony (easy to dye) to imitate ancient jade in order to achieve the purpose of "confusion". B: posing as a stone with a color similar to that of jade; For example, Beijing topaz in the Ming Tombs in Beijing, Laizhou stone in Shandong, white and blue are all like jade, and the stones produced in Lingyan Mountain in Liuhe, Jiangsu are also like jade. The best is very smooth, but the hardness can't meet the requirements of real jade. Some stones are black and bright, but opaque, which can't meet the requirements of jade material.

The choice of jade materials is the key link to identify the authenticity of ancient jade. Must be fine in texture, pure in color, oily and transparent, free of impurities, cracks, stones, bright spots and bright stripes, which can be visually observed. It can also be distinguished by the new tender, old and general visual inspection of jade materials.

In addition to visual inspection, jade with heavy hand feel is dense, while jade with light hand feel is loose. Jade is cooler at the same temperature, while glass or synthetic materials are warmer. Listening to the tapping sound of jade, the jade material with clear voice has high hardness and the dull voice has low hardness. These methods can be combined with the situation at that time and applied flexibly to achieve the purpose of evaluating the quality of jade materials.

In short, if you choose the right jade material, the success rate has already accounted for 50%, because the good jade material price itself has a high gold content. This cannot be ignored. But there are not many good jade materials.

2. Look at the shape of the equipment and check the pattern;

Due to the restrictions of politics, economy, culture and habits, the types of jade articles in each era have their own characteristics of the times. This refers to the orientation of choosing an object (not dating) in a complicated market. Ancient jade has its own system, with traces of evolution law. These laws constitute systematic cognitive knowledge in personal thinking. The market is chaotic, and the time is short, so it needs to be judged instantly. This kind of decision after visual inspection in a very short time is actually a personal potential knowledge at work, which is based on the feeling of knowledge integration. Only when I feel the value of this model will I stop and reach out to observe it carefully.

Different times and different jade fashions have created different patterns. Modeling and ornamentation are inseparable and need to be carefully looked at together. After careful analysis, it is generally clear that ancient jade belongs to that dynasty and generation. How many years ago?

For some nondescript ancient jade, it goes without saying that the shapes and patterns don't match. (Why are you still watching? )

At present, printing technology is advanced and developed. There are many books and paintings published in ancient jade, and the shapes and patterns are clearly printed. Today, with the proliferation of high-tech antique jade, it is not difficult to "clone" the shape and ornamentation of ancient jade according to the pictures. Therefore, when we look at the decorative patterns of utensils, it can only be used as one of the reference items when identifying fakes. Don't think that the shape and ornamentation are right. This jade is definitely right. Don't let it lead us to another misunderstanding.

The shape and ornamentation of vessels is an important basis for dating, which has the characteristics of unit, combination, implication and aesthetics. They come and go in an orderly way, with clear structure, touching momentum and exquisite diversity. They are the cultural characteristics of an era and works of art with both god and emotion.

Imitators don't know the social background and have no skills in this field. The decoration structure is unclear and the explanation is vague. He can only imitate the shape of the work, but it is difficult to imitate the "spirit and emotion" of the work. This problem can only be briefly said, because we don't study the dating of ancient jade now.

Question 6: How to distinguish the authenticity of jade ornaments? First, understand jade knowledge. First, there are too many varieties and too many defective products. View original post >>

Question 7: 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, jade is cold, put a head on the jade, burn it with a lighter, and burn it with the jade head all the time.

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 jadeite 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. ......& gt& gt

Question 8: How to distinguish real jade from fake jade? Simple methods are just some simple methods. It's best to go to the appraisal department to check the authenticity of jadeite. Jade can be divided into nephrite and jadeite, and jadeite is also called 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 some common methods to identify true and false jade articles: (1) Water identification method Drop a drop of water on jade articles. If it is dewdrop-shaped, it is real jade. (2) If the touch method is real jade, it will feel cold and lubricated by hand. (3) When jade is observed in light, the true jade is clear in color and evenly distributed in green. (4) The tip of the tongue identifies that the real jade on the tip of the tongue has astringency and the fake jade does 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. There are six criteria to identify the quality of jade, namely, color, transparency, uniformity, shape, percussion and luster. (1) Jade is the best, and the value of red and purple jade is only 1/5 of 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) Transparent and crystal clear as glass, without dirty spots, chaff and 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) The color of jade is uniform. Although it contains white and green, the color is uneven and its value is very low. (4) Special-shaped 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) Cracks and cuts are common when knocking on jade, which are generally not easy to observe. If you knock with a metal bar or throw jade gently on the table, you can tell whether there is a crack from the clarity of the sound. The louder, the better. (6) There are black spots and flaws in jade that are not easy to be found by naked eyes. As long as you take pictures with a magnifying glass of 10 times, you can have a panoramic view. Natural jadeite is characterized by slight light color, without light blue (commonly known as evil color). There is also a kind of synthetic jade, which is made of jade powder, crystal and salt water. It looks like dark old pit jade. The method of identification is very simple, because the proportion of natural jade can be weighed by hand or with a balance, and the most important one is 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) mainly depends on the transparency, internal structure and luster of the crystal. Real jade is transparent, oily and shiny, with natural patterns, and the internal fiber state is not easy to imitate. (2) Real jade sounds crisp, while fake jade sounds dull. (3) Measurement is mainly about 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.

Question 9: How to distinguish genuine jade from fake jade? It is my own experience! An easier way!

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)

This is a general appraisal, because I sell jade, believe me.

Question 10: What is the easiest way to tell whether jadeite is true or false? This is to see if it is true or not. This is a relatively simple identification method.

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. (If the fire really comes, there will be small water droplets attached to the jade, but if it is fake, there will be no small water droplets attached to the jade.)
