How to tell the authenticity of jade?
2, water identification method: a drop of water on the jade, such as into a dewdrop-like long does not disperse the real jade; water droplets quickly disappeared is shoddy goods.
3. Hang the jade to be identified with a line in the air, and gently knock on it. The sound of the real jade is crisp and pleasant, and the sound is soothing and far-reaching. Fake ones do not have a wonderful sound (this method is applicable to slightly thin jade pendants).
4, hand touch method: the real jade in the hands of a paw, feel heavy, fake paw up lighter. In addition, if the real jade is touched by hand, there is a sense of coldness and lubrication.
5, inspection method: the jade will be towards the bright place, such as sunlight, light, if the color is transparent and natural is real jade.
6. Tongue licking method: The tip of the tongue licking real jade has the feeling of astringency; while fake jade has no feeling of astringency.
7, the magnifying glass to watch: the purchase of jade under a magnifying glass to watch, mainly with or without cracks, no cracks for the top quality jade, cracks for the second. Even if it is a real jade, the value of cracks will be greatly reduced. The more cracks there are, the more obvious they are, and the lower the value will be.
8. Knife scratching method: real jade is harder, no trace with a pencil sharpener, and fake ones are softer, the knife cuts to see the trace. The knife should be used to cut the bottom of the jade or an inconspicuous part of the jade. In addition, some of the Ciu Jade stones have a hardness of between 2.2 and 3, so there may be scratches, which should be identified in practice.
9. The breaks of real jade are uneven, and the material structure is dense. False fracture neat shiny, is a glass type of things; fracture material structure is rough, no wax-like luster is a kind of stone, with more than seven times the magnifying glass to observe carefully, identify its edges, corners, holes, hollowing, carving line place, in the smallest place can be found in the traces of the fake goods.
Secondly, for the types of jade and ancient jade can be identified in the following ways:
1, for the old and new jade, can be identified from two aspects: the old jade surface has a layer of oxidized jade skin, commonly known as the "pulp", like the skin of the pear, and the natural color of the jade has a clear difference, while the new jade is not; Furthermore, from the point of view of the subject matter of the carving, ancient jade is a symbol of rank and power, to the mythical birds and flowers, figures, such as dragons, phoenixes and so on. And the new ones are generally more auspicious subjects.
2, eye and hand combination of identification methods - currently on the market there are 10 yuan, 20 yuan a piece of jade, there are thousands of tens of thousands of value, for which people can through the top grade jade moist, transparent, greasy feeling, pinch in the hands of the feeling of warmth, through the magnifying glass or microscope, you can see that the interior of the jade is a fiber! Through a magnifying glass or microscope, one can see that jade has a fibrous internal structure and fine granularity, while artificial glass has no structure and bubbles can be seen. In addition, you can also use a knife to carve in inconspicuous places of jade, and what you can carve must be fake jade, and what you can't carve is real jade. Because of the increasing rarity of top-grade Hetian jade, each kilogram can reach tens of thousands of dollars to more than 100,000 yuan, while the general Qinghai White Jade, Russian White Jade and other kilograms of thousands of dollars, so some people will be this to mix with Hetian jade. The minerals in these jades are basically the same as those in Hetian jade, but the surface color is grayer and less soft, and will be duller over time.
Question 2: How to recognize real jade from fake? Simple methods Just some simple methods, it is best to go to the appraisal department to test
Identification of real and fake jade
Jade can be divided into two kinds of nephrite and nephrite, nephrite is also known as jadeite. In terms of chemical composition, nephrite is a silicate containing calcium, magnesium and iron, while hard jade is a silicate containing sodium and aluminum.
The following are some common methods to identify genuine and fake jade:
(1) Water Identification Method
A drop of water will be dripped on the jade, and if it becomes dewdrops, it will not be dispersed for a long time.
(2) Hand Touching Method
If it is genuine jade, there is a cold and lubricating feeling when you touch it with your hand.
(3) Observation method
Observe the jade against the light, the color is transparent and the green color is evenly distributed.
(4) Tongue identification method
Tongue licking real jade has an astringent feeling, while fake jade does not.
In addition, you can also use a magnifying glass to observe, mainly to see whether there are cracks, cracks of its value greatly reduced.
Identification of Jade Quality
There are six criteria for identifying the quality of jade, namely, "color, translucency, uniformity, shape, knocking, and illumination".
(1) Color
Jade is best in green, and the value of red and purple jade is only 1/5 of that of green jade; if the jade contains red, purple, green and white, it is known as "Fortune, Longevity and Happiness"; if it contains only red, green and white, it is "Fortune, Longevity and Happiness". Fortune and Longevity". Those with dull, slightly yellowish color are inferior. If it is monochrome jade, the one with even color is good.
(2) Transparent
Transparent and crystalline like glass, with no dirty spots and no chaffing or astringency is the top grade. Translucent and opaque jade are called intermediate and ordinary jade respectively. During and before the Qing Dynasty, jade with red, green and white colors was called jadeite jade. In modern times, Jadeite Jade generally refers to jade that is generally transparent. Currently, jadeite jade is transparent with green color in the countryside.
(3) Uniformity
The color and lustre of jade is important to be uniform, although it contains white and green, but the color and lustre are not uniform, the value is very low.
(4) Shape
The shape of jade can be processed into different styles according to different aesthetic requirements, without any special standard. Generally speaking, the bigger the jade is, the better.
(5) Knocking
Jade often has fractures and cut lines, which are generally not easy to observe. If you knock with a metal rod or gently throw the jade on the countertop, you can identify the existence of cracks from the clarity of the sound. The clearer the sound, the better.
(6) Illumination
If there are black spots or flaws in jade that are not easy to be detected by the naked eye, you can see them with a 10x magnifying glass.
The quality of jade can be categorized into 10 grades, each of which can be subdivided into upper, middle and lower 3 grades. Among them, white jade, regardless of its color and transparency, is the lowest in value.
Natural jade is characterized by a slightly lighter color without the light blue (commonly known as the evil color). There is also a synthetic jade, made of jade powder, crystals and brine, which looks quite similar to the dark-colored "old pit jade". The way to determine is very simple, because it is different from natural jade specific gravity, can be weighed by hand, or weighed with a balance, the heavier for the real jade.
At present, the market is often mixed with some superbly processed fake jade. The general method to recognize fake jade is to look, listen and measure.
(1) Look
Mainly look at the crystal transparency, internal structure, luster and so on. Real jade transparent, grease luster, pattern natural, internal fiber state is not easy to imitate.
(2) Listen
The sound of genuine jade is crisp and clear, while the sound of fake jade is dull.
(3) Measurement
The main measurement is hardness. Take the glass plate (Mohs hardness 5.5) as the standard, except for Ciu jade, turquoise, generally can be scratched on the glass plate, and the jade itself is not damaged at all. Counterfeit jade is generally softer and cannot be scratched on glass.
Common fake jade is generally processed with plastic, glass, they are amorphous materials, low hardness, low density, and the nature of the material characteristics. Such as plastic can be picked with a steel needle to move, or can be carved out of the scratches, held in the hands of light. Glass in the light or sunlight show bubbles inside, polarized mirror shows amorphous (rotation without periodic light and dark changes), there are raw materials to make swirling stripes and so on.
Question 3: How can we recognize the authenticity of jade? How to identify the authenticity of jade Reliable methods of identification are: watching, listening and testing. Look, mainly to see the transparency of the crystal, the real jade transparency is stronger, grease luster; listen, the real jade sound crisp, and vice versa sound muffled; test, the real jade from the glass scratched, leaving scratches on the glass, while the jade itself is unharmed. Common fake jade has plastic, coloring glass, cloud stone (marble), electric color fake jade to jade powder and crystal with brine made of synthetic class with nitrate imitation of jade and other different methods of forgery, the means of identification are different. The texture of plastic is lighter than that of jade, and its hardness is poor, so it is generally still easy to recognize. Coloring off-duty is also easy to distinguish. As long as you get the light or sunlight to check, you will see a lot of air bubbles inside the glass. What is more difficult to distinguish is the electro-colored fake jade, which is intended to be electroplated to give the inferior jade a beautiful emerald green appearance, which can be easily mistaken for real jade. It is easy to mistake it for real jade. At this point, you need to look carefully, if there are some small cracks in the green with blue on top, it is fake jade. Because electroplating will leave cracks, connoisseurs called "spider claws". It is also said that the electric color fake jade placed in hot oil, electroplating color will fade, but also its original face. Synthetic jade made of jade powder, crystals and brine is imitation of dark-colored old pit jade. The identification method is very simple, i.e. they have different specific gravity. Natural jade has a specific gravity of 3.3-3.4, while synthetic jade has a specific gravity of only 2.8, which can be identified by weighing it in the hand, or weighing it with a balance. Jade imitations made with nitrate look whiter and more lustrous than jade. As the old saying goes, "Jade with nitrate must be high". That is, white jade must be like nitrate before it can be regarded as high grade. It can be seen that it is difficult to distinguish between nitrate and jade. However, the real and the fake are ultimately different. As far as color is concerned, white jade is often greenish in white, and there are very few pure whites, while nitrate is a pure white that is even and clean. In terms of the nature of jade, jade is warm and delicate, such as grease and cream, although the nitrate is also warm and moist, glistening in the inevitable thief light. White jade is a natural product, the body is difficult to all uniform and consistent, within the jade tendons, jade flowers. Nitrate for artificial production, there is no such phenomenon. White jade solid texture, no bubbles can be found. Nitrocellulose processing again good, often have air bubbles, air holes exposed. Figure out these articles, will not take the nitrate products as jade. zhonghuayuwenhuawang/.... .ID=278 How to choose and buy jade China's jade variety, a long history. According to the origin, the famous ones are "Southern Jade" produced in Xinyi, Guangdong, "Henan Jade" produced in Henan, "Shandong Jade" produced in Shandong, and "Sheep's Fat Jade" produced in the area of Ili and Hotan in Xinjiang. The more expensive jade jewelry is the "Sheep Fat Jade". Most of the more valuable jade jewelry is made from these jades. To identify the superiority of a piece of jade, the main point to look at is whether its color has the five characteristics of thick (rich), yang (distinct), pretty (color beauty), positive (pure), and (soft). If it basically conforms to these characteristics, it is a top quality jade, i.e. a beautiful jade. If the jade appears to be light (bland), dark (gloomy), old (dull color), flowery (impure), or slanted (incongruous), then it is of inferior quality. When purchasing jade, do not pick it under a strong light. This is because the light tends to make the jade lose its original color, and also tends to cover up some imperfections, so as to disguise it as the real thing. In addition, you should also learn to identify the real and fake jade. At present, there are many kinds of common fake jade on the market, such as plastic, glass, lucite (marble) and electric color. Plastic and marble have lighter texture and poorer hardness than jade; colored glass has some bubbles, which can be found as long as it is taken to the light or sunlight for inspection. Electric color fake jade is more difficult to identify, it is in poor quality jade plated with a layer of beautiful dazzling emerald green appearance, at first glance than the real jade is not a big difference, a closer look may be found, it is often with some "spider claws" (green with blue small cracks).
Question 4: How can we identify the authenticity of jade? What kind of jade is good jade? Chinese jade is divided into two categories: soft jade and hard jade.
Jade, commonly known as "jade", is China's traditional jade in the rising star, but also in recent times all the jade in the top grade. Common jadeite color is white, gray, pink, light brown, green, emerald green, yellow-green, purple-red, etc., most opaque, individual translucent, glassy luster. According to the color and texture, there are gemstone green, brilliant green, yellow Yang green, Yang Pretty green, glass green, parrot green, spinach green, light water green, light Yang green, frog green, melon green, plum green, blue green, gray green, oil green, as well as violets and lotus root pink ground and more than twenty varieties.
Soft jade is called real jade, such as white jade, green jade, clear white jade, jasper and nephrite, etc. They all have a waxy luster, pure milky white, and from the jade of all times, the jade used in our country is dominated by nephrite, and the ancient nephrite is known as traditional jade in China. The common colors of nephrite are white, off-white, green, dark green, yellow, black, etc. Most of them are opaque, individually translucent, with glassy luster, and the varieties of nephrite are mainly classified according to different colors. The best white jade is as white as sheep's fat, and is called sheep's fat jade. Green jade is grayish white to greenish white, and some people currently refer to grayish-white green jade as greenish-white jade. Jasper is green or dark green, sometimes with black dirty spots, which are caused by impurities such as chromium spinel minerals. When it contains many impurities and is black in color, it is the precious nephrite. Topaz is also a more precious variety. Green jade in the sugar water yellow crust, existing people called it "sugar jade", white slightly pink people called "pink jade", tiger skin color is called "tiger skin jade" and so on.
People who play with jade for the first time are afraid of encountering fakes because they don't know jade. Currently on the market to identify glass imitation jade products, I'm afraid that the most common, the simplest kind of forgery. Commonly known as the "jade" of the smooth small circle, small chicken heart, jade plate piece. This kind of glass products because it is poured into the mold, together with the high temperature of the glass liquid in the edge of the object more or less will overflow a little, after cooling to become a hidden raised Fan line. Hand touch, eye will be found. If you take a magnifying glass to reflect the light observation, which must have large and small bubbles.
If you don't ask the experts to identify the authenticity of jade, you can observe from three aspects:
First, because the glass texture is very brittle and hard, the structure is arranged sparsely, and the lack of jade's denseness and toughness can't withstand the strong high-speed spinning carving, so it's generally not possible to produce high-relief carvings and round carvings on the glass.
Second, use a magnifying glass to look for bubbles, even if you can only see one, you can also confirm that it is not jade.
Third, the glass to add chromium oxide, color near ruby; add cobalt oxide, color near sapphire; add chromium oxide and copper oxide, color near emerald ...... so on and so forth, and a good variety of fake jade. But their hue is always thin, lack of natural jade color of oil, thick feeling.
The identification of new and old jade is different. The identification of new jade focuses on the authenticity of the species, the quality of the texture and the thickness of the carving. The appraisal of old jade is relatively complicated. In addition to several basic requirements for new jade, it is necessary to recognize the production of jade and its historical value.
Question 5: How to recognize the authenticity of jade? True and false identification is to distinguish the authenticity of ancient jade, is the primary stage of screening ancient jade, not a higher level of broken generations. It can be done in the following steps:
One. Pin jade material:
1. Official imitation of ancient jade: more pure white jade, green jade and jasper. Official imitations have a source of jade material.
2. Ancient imitations of jade wares: Most of them were made of pure green jade and jasper. At that time, the jade workshops were still able to obtain this kind of jade material, and they would not use the inferior quality of jade material to satisfy the needs of the dignitaries in the society. The leftover jade materials were made into small pendants to satisfy the needs of the common people.
3. Modern high imitation jade: the source of jade material is drying up, especially the old jade material is more difficult to find. What is the solution to the problem of material? a: Use the remnants of ancient jade objects to make them. b: Choose the newly mined Xinjiang Jasper, Gobi Jade, Qinghai Material, Northeast Yellow Material, River Feeling Jade (Yellow Material Seed Material), Dushan Jade (Nanyang Jade has two origins), Serpentine (Cuiyan Jade has 13 origins), Korean Jade, Russian Jade, and so on, which are of better texture, without flaws and spots. Early synthetic jade materials are also in the mix. The vast majority of these materials can reach a hardness of 5.5-6. The polished jade is very glossy, which makes it easy to get the buyer's approval.
4. Modern folk antique jade imitations: low price to capture the market. a: generally do not use the slightly higher price of high imitation of jade materials, and use low-priced spot-colored jade, locks, mottled jade, or with the stone quality of the heavier folder of poor quality jade, but unfortunately, to help the miscellaneous colors, the nature of the stone (easy to dye), imitation of antique jade in order to achieve the purpose of the "mess real. b: To pass off jade as stone with similar colors; for example, Beijing's Beijing Topaz from the Thirteen Tombs, Shandong's Laizhou stone, white and turquoise are quite similar to jade, and the stone produced in Jiangsu's Liouhe Lingyan Mountain is also very similar to jade. Good very light and moist, but the hardness are not up to the requirements of real jade. Some of the stone and black and bright, but not translucent, are not up to the requirements of jade.
Evaluation of jade materials, in determining the authenticity of ancient jade is a relatively critical link, must be selected texture, color and lustre pure, oily, permeability, good, no impurities, no locks, no folder stone, does not contain bright spots, bright strips, etc., which can be visually inspected. In terms of the newness of the jade material, the old, the old, and the general visual inspection can also be distinguished.
In addition to the visual inspection method, the jade material that feels heavy in the hand is dense in texture, while the light one is loose in texture. The cooler ones are jade materials at the same temperature, and the warmer ones are glass or synthetic materials. Listen to the knocking sound of jade, the sound brittle jade material hardness is high, the sound muffled hardness is low ....... All these methods can be combined with the situation at the time, and be utilized flexibly to achieve the purpose of evaluating the quality of jade materials.
In short, if the jade material is selected correctly, the success rate has accounted for 50%, because the price of good jade material itself has a high gold content. This point can not be ignored. However, there are not many good jade materials.
II. Look at the type, inspect the decoration;
Jade ware type of each era, subject to political, economic, cultural and customary limitations, have their own era characteristics, here is a general reference to the selection of the complicated market orientation, (not to break the generation). Throughout the generations of ancient jade, the type system has become a system of its own, with the evolution of the trace of the law, these laws will be composed of individual thinking in the system to identify knowledge. The market to see the type of clutter, the time is very short, instantly have to make a judgment, this very short period of time after the visual inspection of the decision, in fact, is the potential knowledge of the individual at work, is to knowledge synthesized as a feeling of experience. Simply feel that this type of weapon to look at the eye, will stop, reach out, look closely.
Different eras and different styles of jade use resulted in different ornamentation. Modeling and ornamentation are inseparable, need to be combined with a close look at the general analysis after a close look, roughly clear in the hands of the ancient jade belongs to that dynasty, that generation. How many years ago.
For some of the modeling and ornamentation does not match, incongruous ancient jade, without saying that the heart has been self-evident. (And why look at it?)
At present, the printing technology is advanced and developed, the publication of this kind of ancient jade books, pictures are very much, the shape and ornamentation are printed very clearly, in today's high-tech developed antique jade proliferation today, according to the map "clone" ancient jade type ornamentation is not a difficult task. Therefore, when we look at the vessel type and decoration, it can only be used as one of the references in the identification of counterfeiting. Don't think that if the shape and decoration are right, the jade is definitely right. Don't let it lead us into another misunderstanding.
The shape of the vessel and the decoration is an important basis for identifying the generation, there are units, combinations, symbols and connotations of beauty, coming and going in an orderly manner, the structure is clear, the momentum is touching, exquisite and diverse, is the cultural landscape of an era, is the God, the feelings of both the artwork.
The imitation copyists do not understand the social background and does not have the power in this area, the decorative structure is not clear, explaining the ambiguity, and thus can only imitate the shape of the work, it is difficult to imitate the work of the "God and love". This problem can only be a simple cut off, because we do not study the ancient jade break.

Question 6: How to identify the authenticity of jade jewelry First understand the knowledge of jade first There are too many varieties There are too many substandard View original post >>
Question 7: How can I identify the real and fake jade? Teach you a simple method:
1, look at the sun, jade in some cloudy things, a ball, like cotton wool.
2, the hardness of jade is very high, like diamond, so you can scratch a trace on the glass.
3, jade is cool, put a head on the jade, with a lighter to burn, stick to the jade hair burning constantly.
Jade classification:
Jade can be divided into nephrite and nephrite, both for two different minerals. Nephrite comes in translucent white, yellow, green and black colors, with an even distribution of colors, while nephrite comes in white, purple, yellow and green colors, with an even distribution of colors that varies from species to species.
The vast majority of jadeite produced in China is nephrite, and "white nephrite" is one of the most precious of all nephrite, with a delicate texture and white color, and many exquisite jade artworks are carved from nephrite.
The main source of jadeite is Myanmar, which is even rarer than nephrite. Since jadeite is superior to nephrite in terms of quality, color and price, jade jewelry in the market is mainly made of jadeite, and there is a great demand for jadeite, so we will focus on jadeite - Jadeite in the next section.
Appreciation of Jadeite:
Appreciation of Jadeite is based on color and quality, which can be broken down into color, transparency, clarity, cut and cracks, and usually starts with the color.
Color
Color is the most important factor affecting the value of jadeite, can be assessed from the following four categories of jadeite color:
To be pure: pure refers to the proportion of jadeite main color and secondary color, green jadeite, for example, pure green is the best, green with yellow or blue is second, with gray is the worst.
To be appropriate: on the color shades, of course, the thicker the better, but the color is too thick will cause the opposite effect, reduce the quality of jadeite.
To be sharp: the more vivid and bright the color of jadeite, the more attractive it is, and the more grey or black it contains, the duller the color will be
To be even: the more even the distribution of color, the better, and the higher the value.
Transparency
The transparency of jadeite affects the refraction of light, which in turn affects the overall beauty. When light enters a transparent and delicate jadeite, it will reflect a beautiful light, making people feel that the jadeite is crystal clear, greatly increasing its beauty. On the contrary, if the light meets a low transparency and rough texture of the jadeite, it will reflect the dull light, so that the attractiveness of the jadeite greatly reduced.
Clarity
Clarity refers to the flaws contained within the jadeite, mainly white and black, which are caused by other minerals contained within the jadeite, relatively speaking, black flaws are more obtrusive than white. The less impurities in the jadeite, the better.
Cutting
The processing of jadeite products is divided into two categories, namely, polished and carved. As the surface of the finished product is not covered, the raw material requirements are higher. Apart from no cracks, the proportion of the cut, thickness and symmetry of the product are also very important, which can affect the appearance of the finished product. For example, a well-cut "egg surface" should not be too thick or too thin, and the "dib" position should be in the center, and the proportion should be moderate.
Evaluating floral pieces is mainly a measure of their beauty and the fineness of the carving. Often cracked jadeite will be treated with floral carvings to hide its flaws.
Cracks
Cracks can greatly reduce the value of jadeite. If a jadeite jewelry piece has cracks, it may split along the cracks at the slightest impact. Therefore, you need to be extra careful when purchasing jadeite jewelry. Generally speaking, it is easy to detect the presence of cracks by using a flashlight.
High-quality jadeite can be sold at a considerable price, but the supply on the market is limited, and some businessmen, in order to achieve better profits, do not hesitate to carry out artificial treatment processes for jadeite. Therefore, there are A-goods, B-goods and C-goods in the market.
Artificial Treatment of Jadeite
C Goods
C Goods refers to the fake color jadeite that has been artificially colored. The method is to use high temperature and pressure to infiltrate the dye into the original colorless jadeite, so that all or part of it is dyed emerald green or purple, but its color will fade over time and become dull.
B-grade
B-grade refers to jadeite that has been chemically cleared of surface blemishes, impurities, and yellow parts, retaining only the original green and white elements, and then injected with epoxy resin glue into the jadeite as a reinforcement to make the whole jadeite look more transparent and more colorful. As the internal structure of jadeite has been damaged during the chemical treatment, the structure becomes loose, so B-goods can easily show cracks on the surface. If a coloring agent is added during the treatment, it is called B+C goods.
Natural Jadeite
A Goods
A Goods refers to the natural Jadeite that is completely free of artificial chemical treatment.
The predecessors of China's jewelry industry, in the long-term production practice of jadeite processing, summed up a lot of experience related to jadeite, and in the form of a brief and concise aphorism, expressed these characteristics of jadeite. ...... >>
Question 8: How to identify the real jade fake jade? Simple methods Just some simple methods, it is best to identify the department to detect the true and false jade identification jade can be divided into two kinds of soft jade and hard jade, hard jade, also known as jadeite. In terms of chemical composition, nephrite is a silicate containing calcium, magnesium and iron, while hard jade is a silicate containing sodium and aluminum. The following is an introduction to some common methods of identifying genuine jade: (1) Water identification method will be a drop of water on the jade, if it becomes dewdrops, long does not disperse is genuine jade. (2) Hand Touching Method: If the jade is genuine, there is a sense of coldness and lubrication when you touch it with your hands. (3) Observation Method: Observe the jade against the light, the color is transparent and the green color is evenly distributed. (4) Tongue tip identification method: The tongue tip licking of genuine jade has an astringent feeling, while that of fake jade does not. In addition, you can also use a magnifying glass to observe, mainly to see whether there are cracks, cracks of its value greatly reduced. Identification of Jade QualityTo identify the quality of jade, there are six criteria, namely, color, translucency, uniformity, shape, knocking, and illumination. (1) Jade with green color is the best, and the value of red and purple jade is only 1/5 of that of green jade; if a jade contains red, purple, green and white, it is known as Fuk Luk Suk Hei; if it contains only red, green and white, it is known as Fuk Luk Suk Hei. Jade that is dull and slightly yellowish in color is considered inferior. If it is a monochrome jade, it is better if the color is uniform. (2) Transparent and crystalline jade that is as clear as glass, with no dirty spots and no chaffing or astringency is considered to be of top quality. Translucent and opaque jade are called intermediate and ordinary jade respectively. During and before the Qing Dynasty, jade with red, green and white colors was called jadeite jade. In modern times, Jadeite Jade generally refers to jade that is generally transparent. Currently, jadeite jade that is transparent and has a greenish color resides in the countryside. (3) Uniformity of color and lustre of jade is important, although it contains white and green, but the color and lustre are not uniform, the value is very low. (4) The shape of jade can be processed into different styles according to different aesthetic requirements, without any special standard. Generally speaking, the bigger the jade, the better. (5) There are often fractures and cut lines in jade, which are generally not easy to observe. If a metal rod is used to knock on it, or if the jade is gently thrown on the countertop, the presence or absence of cracks can be identified from the clarity of the sound. The clearer the sound, the better. (6) When there are black spots and imperfections in jade that are not easy to be detected by the naked eye, you can see them clearly if you look at them with a 10x magnifying glass. Natural jade is characterized by a slightly lighter color, not light blue (commonly known as the evil color). There is also a synthetic jade made from jade powder and crystals with brine, which looks rather like dark-colored old pit jade. The method of identification is very simple, as it is not nailed down with the specific gravity of natural jade, so it can be weighed by hand or weighed with a balance, and the heavier one is the real jade. At present, the market is often mixed with some superbly processed fake jade. The general method to recognize fake jade is to look, listen and measure. (1) Look at the crystal transparency, internal structure and luster. Genuine jade is transparent, greasy luster, natural pattern, and the internal fiber state is not easy to imitate. (2) Listen to the sound of genuine jade, and the sound of fake jade is muffled. (3) Measure mainly the hardness. Take a glass plate (Mohs hardness 5.5) as the standard, except for Ciu jade and turquoise, generally it can be scratched out on the glass plate, while the jade itself is not damaged at all. Counterfeit jade is generally softer and cannot be scratched on glass. Common fake jade is generally processed with plastic, glass, they are amorphous materials, low hardness, low density, and the nature of the material characteristics. Such as plastic can be picked with a steel needle, or can carve out scratches, held in the hands of light. Glass in the light or sunlight show bubbles inside, polarized mirror shows amorphous (rotation without periodic changes in light and dark), there are raw materials to make swirling stripes and so on.
Question 9: How to identify the real jade? Is my own experience! Comparison of simple methods!
1; is to put the jade on the face, feel very cold, after two or three seconds there is not cool that is true. Because jade heat transfer fast heat dissipation is also fast! If the paste on the face is not cool is false.
2; is that the magnifying glass to 10 times or 30 times to see the inside of the crystal, see if there is like a spider's web of small cracks, and is the color is not in the cracks or on the surface of the jade if there is that is false. Hetian jade looks like rice paste because the crystals are more delicate and the color is more uniform. Jade looks like a fly wing, some like a little bit of Sha Xing, and like broken glass, because the jade crystal is not fine enough color is not uniform, there are many kinds of colors in the same piece of jade above.
3; is to destroy the identification, take the fire. It is burned black, burnt, burnt yellow, odor. Black and yellow if that water can not be washed off, and the original color is not the same is false. Scorched and smelly are even more fake. (Really that fire to burn there will be small water beads attached to the surface of the jade, and burned black with a wash of water to restore the original color. However, we generally do not use this approach, this is not good for the jade)
General is this identification, because I am selling jade, believe me right
Question 10: The simplest way to identify the authenticity of jade? This is to see the true and false This is a relatively simple way to identify the true and smooth!
1; is to put the jade on the face, feel very cold, after two or three seconds there is not cool description is true. Because jade heat transfer fast heat dissipation is also fast! If the paste on the face is not cool is false.
2; is that the magnifying glass to 10 times or 30 times to see the inside of the crystal, see if there is like a spider's web of small cracks, and is the color is not in the cracks or on the surface of the jade if there is that is false. Hetian jade looks like rice paste because the crystals are more delicate and the color is more uniform. Jade looks like a fly wing, some like a little bit of Sha Xing, and like broken glass, because the jade crystal is not fine enough color is not uniform, there are many kinds of color in the same piece of jade above.
3; is to destroy the identification, take the fire. It is burned black, burnt, burnt yellow, odor. Black and yellow if that water can not be washed off, and the original color is not the same is false. Scorched and smelly are even more fake. (Really that fire to burn there will be small water beads attached to the jade fake there is no small water beads attached to the jade)
