You are too powerful.

The trace value of jade is too complicated.

Let me tell you what Jed thinks first.

First, color: beautiful color is the first requirement. At present, the most pleasing color is bright green (green tender). Although the color on it is dark green,

It's too dark green, which makes people feel too dull, so the top grade dark green is not as high in price as bright green.

Second, transparency: high transparency has a great influence on the value of jade. Transparent jade gives a cool feeling, but opaque jade, color.

No matter how bright the green is, no matter how tender it is, it gives people the impression that the color is too dull and lacks vivid aesthetic feeling. Usually transparent jade is called "glass seed" in the market.

Translucent jade is called "ice seed" or "Guanyin seed", and opaque jade is called "hibiscus seed" or "taro seed".

Third, uniformity: the uniformity of color is directly proportional to the numerical value. The price difference between the whole piece of green jade and only some green jade is several figures;

The distribution position of color also has a great relationship. A little green in the conspicuous place is naturally more pleasing to the eye than the green distributed on the edge.

Shape: Jade is not valued by weight like other precious stones. The value of jade mainly lies in its shape, size and thickness. The bigger, the thicker.

Valuable, but small and thin jade will be less expensive. In addition, its shape is also very important, because most people in China buy jade with the psychology of seeking good fortune and avoiding evil.

The appearance of jade has the shape of colorful emblem, such as fish (more than one year), peach (longevity) and coin (making money into treasure). , I will

More attractive to buyers and sellers than ordinary flowers and plants.

5. Knock: This is a special way to choose jade bracelets. Jade is good, it sounds crisp. If the jade itself has flaws, such as cracks and internal cavities.

Or when it is partially deteriorated, the sound of knocking will be different. That kind of feeling is like beating defeat, and the sound becomes a "click" sound.

6. Figure: Pick it up and look at it under strong light, and you can see the color and flaws of jade at a glance. Sometimes the surface of jade looks perfect.

It was only after filming that the flaw was discovered. In addition, the color distribution can also be distinguished by the action of light and the illumination of light.

Whether it is natural or not, and synthetic jade (fake jade) can't escape the checkpoint of "taking pictures". It's just a skill of "taking pictures", and it still needs to be experienced.

Only those who have passed the exam are warm enough, and most people may not see why.

7. Price: This is a very simple identification method. As the saying goes, "value for money", especially in the jewelry industry. There is absolutely no bargain.

Good things, usually cheap goods are mostly fakes, so when we buy and sell, we can infer from the price that good jade can't be sold.

The price is low, so when you see a beautiful jade and ask the price, you find it very cheap. The first reaction is that there is something wrong, and it is definitely not.

Be greedy and cheap, so as not to be cheated, not to lose.

How to distinguish the quality of jadeite from its appearance?

First, because glass is very brittle and hard, its structure is loose, and it lacks the density and toughness of jade, so it can't stand strong and high-speed rotary carving. Therefore, in

Generally, high reliefs and round carvings cannot be processed on glass.

Second, use a magnifying glass to find bubbles, even if you can only see one, it is glass.

Thirdly, chromium oxide is added into the glass, and the color is close to ruby; Adding cobalt oxide, the color is close to sapphire; Add chromium oxide and copper oxide, emerald color, etc.

There are many colors. However, its color tone is always relatively thin, lacking the oily and rich feeling of natural jade color. More difficult varieties, using polymer materials.

The material is mainly fake jade. Its color can be adjusted at will, and it is difficult to find bubbles under a magnifying glass. It is said that the original shape can be displayed on the infrared spectrometer, but it can be visually observed.

In addition to the general unrealistic destructive inspection, breaking the stone section and burning to see its reaction, the key depends on whether there are natural stone lines on the surface of the device. mankind

After all, it is unnatural for processing, and it will be exposed under a magnifying glass.

● Identification, including 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 content has been

However, when it comes to the identification of Lao Yu, it is unusual. In addition to several basic requirements, new jade also needs to know the production time and history of jade.

The value of the world.

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. receive

Try to refer to the papers on the characteristics of jade in a certain era, and connect with each other, and your jade dating level will be rationally improved.

At this time, you should contact the physical objects as much as possible to correct the parallax between the pictures and the physical objects in the book.

In addition, the judgment of the times allows a certain span on some jade articles. Because jade and stone tools are precious and not perishable, as family heirlooms,

Bao, early jade articles appeared in tombs hundreds of years later, and there were many precedents. Jade articles in the late last era and the early next era

The style of the equipment is not completely consistent. Jade has no date, and subtle differences are normal.

Hand-carved, beautifully carved, smooth to the touch, perfect in jade, moist and oily, delicate and meticulous, full of aura, flawless and exquisite.

Delicate in conception.

The temperature of jade is relatively low and it is not easy to transfer heat. If you put it in your hand, you can see how the temperature changes slowly.

It is good for me to have the above three points, but it is the opposite to have none at all.

How to distinguish the quality of jade mainly depends on the transparency of crystal. 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 and electro-color fake jade, which is made of jade powder and crystal with salt water.

Different methods of counterfeiting, such as jade, have different identification methods.

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. this

You need to observe carefully. If there are some small cracks with blue in the green, they are fake jade. Because electroplating will leave cracks, experts call them "cracks"

Spider claw "Some people say that if the fake jade with electric color is put in hot oil, the color of electroplating 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. Specific gravity of natural jade

3.3-3.4, while the proportion 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 must be like nitrate in order to be counted.

It is advanced. 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 bluish and pure.

There are few white people, and nitrate is pure white. As far as the nature of jade is concerned, jade is moist and delicate, such as cream, while nitrate is moist and shiny.

But there will inevitably be thieves. White jade is a natural product, and it is difficult to have a unified structure, including jade ribs and jade flowers. If nitrate is artificially made, it will be supreme.

Describe the 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. Find these things, and you won't put nitrate

This product is regarded as jade.

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. Remembering these maxims and being able to understand and appreciate their profound connotations will benefit you for life.

Don't look at the color under the lamp.

In fact, any jewelry should not be evaluated under the lamp. This is especially important for jadeite. This is because the color of jadeite, especially the color of jadeite such as flashing gray, flashing blue and oil blue, has a much better visual effect under light than under natural light. Therefore, under the light, we can only look at the cracks, water head length, reflection degree or other characteristics of jadeite. But to investigate and evaluate the green color of jadeite under natural light.

The color difference is first-class, and the price difference is ten times.

For high-grade jadeite, the price difference is more than ten times. For example, a jade ring of 500,000 yuan and a jade ring of 5 million yuan are first-class in quality, style, size, planting moisture and defects, and the key to the price difference between them lies in the level of green. How to recognize and distinguish the differences between emerald green is extremely important, at least we have seen and experienced it. "Look more and buy less" For the purchase of jadeite original stone, "look more" is a selection process; It is a comparative process; It is also a process of experience accumulation and verification; It is the premise of "buying". "Buy less" does not mean not buying, but reminding you to "look" before buying. "It is better to buy a large piece than to buy a thread." As for the green morphological characteristics in the original jade stone, "a thread with green" and "a large piece with green skin" are two manifestations of the same green form, which is the difference between "a line" and "a piece". The thickness of "line" is known, but the depth is unknown; The area of the "sheet" is known, but the thickness is unknown. The key to the motto is to remind people not to be confused by the green "more" and "less" on the surface of jadeite, but to recognize the essence of green "standing" and "lying". So, I don't really buy a large piece of green jade, but I remind you not to expect too much from the thickness of green.

Ancient jade appraisal has several points:

First, process trace identification

Second, the oxidation identification

Third, the identification of condensed water

Fourth, the evaluation of artistic level.

Five, Qin color identification

Sixth, odor recognition.

Which is divided into (1), modeling and discrimination. (2), jade, jade material discrimination (3), decoration discrimination (4), style discrimination.

The identification of Qin color focuses on learning and understanding the color change between ancient jade and objects that have been in contact with various storage environments for a long time, but it is actually a physical phenomenon, and the natural quality change it produces is color change. We usually call it "Qin color". For example, ancient jade stored in red paint may be red, black paint may produce black, and buried in loess may produce yellowish brown mud. Observing under strong white light, Qin color usually occurs in the place where jade contact is weak or naturally cleavage wrinkles. Then along the cleavage or fissure, the penetration expands, which can seriously soak the whole organ, which is called "total immersion". After playing, the color is bright, and the color of the piano mostly changes from gray to red. The important point is: under normal circumstances, genuine products are relatively simple; The darker the color, the more chaotic the piano color and the bright piano color are questionable. Even if the real jade has cleavage and cracks, it is not a contact part and does not necessarily have bright colors. Imitate the color of the piano by chemical or physical methods, usually the whole piano. There is also local soft mud, which is characterized by its Qin color. It is not necessary to burn pseudo-ooze in the soft rib or crack of jade. This can be observed under intense white light. However, it is useful to forge the Qin color by laser along the cleavage or fold of jade with high technology. Another point is that the storage environment of jade is dry or jade is dense. Look at the color: natural jadeite has natural color, uneven distribution, prolonged green trend and generally no fluorescence.

Look at the polished surface: the polished surface of natural jadeite is fine and smooth, with grease showing a strong glass luster. If you look closely at the polished surface, you can usually see the mottled crystal interwoven structure. In general, the variegated crystal particles of the same jadeite are uniform in size; At the same time, slightly transparent to opaque white fibrous crystals can be seen, commonly known as "stone flowers".

Listen to the sound: tap the natural jade gently, making a crisp and pleasant sound. If it is artificially processed, it will make a dull sound.

In addition, because of the high density of jadeite, it feels like a thug by hand; Jade has a strong water-holding ability. When it drops on it, the water drops protrude higher.

At the same time, experts remind consumers that when buying high-priced jewelry and jade, they should choose regular and well-known jewelry stores or large and reputable shopping malls. Also remember to ask the merchant for the jewelry and jade appraisal certificate with "CMA" and "CAL" marks. Usually, every precious piece of jewelry and jade has a certificate to ensure that the purchased jewelry and jade are consistent with the certificate, and the certificate is accompanied by photos.

First-class jade, moist, thorough and greasy, is moist in your hand. The main method to identify the authenticity is to use a magnifying glass or microscope to see that there is a fiber interwoven structure inside the jade, and the particles are fine; Artificial glass has no structure and bubbles can be seen. You can also carve it in an inconspicuous place with a knife. What can be carved must be fake jade, but what cannot be carved is real jade. As the saying goes, "Gold is valuable, but jade is priceless". 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 Hetian jade, but the surface color is dark and not soft, which will be even dimmer after a long time.

Old jade and new jade can be distinguished from two aspects. There is an oxidized jade skin on the surface of the old jade, commonly known as "patina", which is similar to the skin of autumn pear and obviously different from the natural color of jade, while the new jade does not. Judging from the theme of sculpture, ancient jade is a symbol of rank and power, and there are many mythical flowers, birds and figures, such as dragons and phoenixes. New ones are generally auspicious themes.

Identification method of water → Drop a drop of water on jade, if it is dewdrop-shaped, it is real jade; The water droplets disappear quickly, which is a fake.

Touch by hand → Real jade will feel cold and lubricated if touched by hand.

Inspection method → Put jade in bright places such as sunshine and light. If the color is clear and the green is evenly distributed, it is a real jade.

Licking the tongue → licking the real jade with the tip of the tongue has a astringent feeling; Fake jade has no astringency.

Magnifying glass viewing method → Put the purchased jade under a magnifying glass to watch, mainly to see whether there are cracks. The jade without cracks is the best quality jade, 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.

Look at it.

So complicated

Let me give you another piece of advice.

Don't buy things online that you don't even know the value of.
