How to quickly distinguish the authenticity of jade?

With the improvement of people's living standards, more and more people buy jade to decorate their lives. However, jade is expensive, the selection technology is very demanding, and the vast majority of consumers are difficult to distinguish its advantages and disadvantages, real and fake, and it is easy to buy inferior products or fakes if you are not careful. So, how can you tell the real from the fake?

1. Water identification method A drop of water is dropped on the jade, and the one that does not disperse for a long time is the real jade; The droplets disappear quickly are counterfeit goods. 2. Hand touch method If the real jade is touched by hand, there is a feeling of cold lubrication. 3. Inspection method Facing the jade to the light, such as sunlight and light, if the color is clear and evenly distributed, it is the real jade.

One can identify by a combination of sight and touch. The high-quality jade is moist, transparent, greasy, and has a warm feeling when pinched in the hand, and through a magnifying glass or microscope, you can see that the inside of the jade is a fibrous interwoven structure with a fine particle size. When looking at the color, see whether the color has the characteristics of rich, distinct, beautiful color, soft and pure, if it basically has the above characteristics, it is beautiful jade.

The method of identifying jade is as follows:

1. Look at the feel.

When the jade is held in the hand or pasted on the **, the natural material of jade gives people a cold feeling, while the fake jade will feel milder and has no cold feeling.

2. Listen to the sound.

In addition, jade can also be identified by listening to sounds, when gently tapping the surface of jade with chopsticks, the natural material jade will make a crisp and pleasant sound after tapping, while the fake jade will make a dull, dull sound.

3. Weigh the weight.

Jade can also be identified by weighing the weight, the natural material of jade structure is dense, the proportion is heavy, and there is a certain pressure on the hand. The fake jade has a loose structure and feels relatively light in the hand.

Introduction to Jade:

Jade is a mineral, there are two kinds of soft, hard, and the jade usually refers to nephrite. It is one of the most common pieces of jewelry. According to the "Tengyue Rural Chronicles" written by Qing Jinshi Cun Kaitai, it is recorded:

Teng is the number of extracts, the jade work is full of thousands, made into utensils, and sold in various provinces of Yunnan. High-grade jade, mostly sent to eastern Guangdong, Shanghai, Fujian, Zhejiang, Kyoto.

China is the earliest and most extensive country in the world to mine and use jade. There are many records in ancient books, and there are many names, such as water jade, relic jade, peiyu, fragrant jade, nephrite jade, etc. The tremolite nephrite jade block unearthed from the Chahai site in Fuxin City, Liaoning Province, is about 8,000 years old (early Neolithic Age), and is the earliest true jade known in the world so far.

The most famous jade in China is Xinjiang Hetian jade, which is known as China's four famous jades, along with Henan Dushan jade, Liaoning's Xiuyan jade, and Shaanxi's Lantian jade.

Methods for identifying the authenticity of jade: head identification, crack identification, sound identification, and hardness identification.

1. Head identification.

The water head refers to the refraction of light, that is, the transparency, and the natural jade is transparent and bright, and the color is natural; Fake jade, on the other hand, is dull and dull, and the color is vain, completely lacking the realism of natural tones, and will lack color roots.

2. Crack identification.

Observing the front, back, inner and outer sides of jade, under high-powered magnification, fake jade will often be filled with a layer of wax to cover up some crack defects, if acid etching lines, that is, spider web lines, can be clearly seen, it means that it is a fake.

3. Voice identification.

Hanging the jade in the air, and then gently tapping with something harder, the natural jade can make a crisp sound, the sound is relatively clear, and accompanied by sonorous penetrating power and lingering aftersound; And the sound of the fake jade is relatively dull, with no penetrating power and aftersound.

4. Hardness identification.

Real jade is very hard, gently scratch on the glass, there will be no marks on the surface of the natural jade, and scratches will be left on the glass; Fake jade generally does not have such a high degree of hard limb rot, but will be scratched by glass.

How to preserve jade

1. Do not collide with hard objects. Although the cracks are not visible to the naked eye, the molecular structure of the jade surface has been damaged, resulting in dark cracks, which will be revealed over time, greatly damaging its exquisiteness and collection value.

2. Avoid dust and oil as much as possible. If there is dust on the surface of jade, it should be cleaned with a soft brush; If there are dirt or oil stains attached to the jade surface, you can use warm soapy water to scrub and then wash with water.

3. The jade pendant should be put properly when not in use, and it is best to put it in the jewelry bag or jewelry box to avoid injury.

4. Avoid contact with perfume, chemicals, soap or human sweat. Because when jade comes into contact with too much sweat, it will be eroded, causing damage to the outer layer and affecting the original vivid color. In particular, white jade-mutton fat white jade is more resistant to sweat and oil, and should be wiped with a weak cloth after wearing.

5. Do not leave direct sunlight for a long time. When jade is exposed to sunlight, it expands when exposed to heat, and the molecular volume increases, which will affect the quality of jade, so it is more avoided to be close to the heat source.

6. You can use tea to raise jade, and the way of raising jade is similar to the method of raising tea pets, such as: the jade raised by green tea is bright, the jade raised by red calendar refers to the leakage of tea, and the jade raised by Fu tea has probiotics that are beneficial to the body, and the jade raised is not easy to break.

In general, it is not very difficult to distinguish the authenticity of jade.

One is to see if the jade quality is natural, if it is too transparent and there are no flaws, the possibility of fakes is relatively large; The second is to look at the color, the color is natural, not too uniform is true, otherwise the possibility of fakes is high; The third is that the "beautiful" and inexpensive jade is basically fake, and it is impossible for the seller to deal with his genuine goods at a cheap price; Fourth, the stalls and scenic goods are basically either fake or junk goods, and they must not be.

The jade and jade industry is very deep, and it is necessary to be cautious.

Reliable ways to distinguish are: see, hear, test.

Look, mainly look at the crystal transparency, the real jade has strong transparency, and the oil is polyid?

Listen, Zhenyu's voice is crisp, on the contrary, the voice is hoarse;

In the test, the real jade was scratched through the glass, leaving scratches on the glass, while the jade itself was not damaged in the slightest.

Common fake jade includes plastic, colored glass, marble (marble), electric fake jade, jade made of jade powder and crystal and salt water, and jade imitated by glass, etc., and the means of identification are also different.

The texture of plastic is lighter than jade, the hardness is poor, and it is generally easy to identify.

Coloring off-duty is also easy to distinguish. As long as you take it to the light or check it in the sun, you will see that there are many bubbles in the glass.

It is more difficult to distinguish the electric color fake jade, which is plated to coat the inferior jade with a beautiful emerald green appearance, and it is easy to mistake it for real jade. At this time, you need to observe carefully, if there are some small cracks with green and blue on it, it is fake jade. Because of the cracks left during plating, connoisseurs call them "spider claws".

It is also said that if the electric color fake jade is placed in hot oil, the plating color will fade and its original appearance will be restored.

Synthetic jade made of jade powder, crystal and salt water is imitation dark old pit jade. The identification method is simple, i.e. they differ in specific gravity. The specific gravity of natural jade, while the specific gravity of artificial synthetic jade is only. Weigh the weight by hand, or weigh it with a balance to distinguish the real from the fake.

The jade imitated with glass looks whiter and smoother than jade. The ancients said: "Jade is bound to be high."

That is, white jade must be like a glass to be considered high-grade. It can be seen that it is difficult to distinguish between glass and jade. However, truth and falsehood are different after all.

In terms of color, white jade is often bluish in white, and there are very few pure whites, while glass is pure white with uniform whiteness. As far as jade is concerned, jade is warm and delicate, like fat and paste, although the glass is also warm, it is inevitable that there will be thief light in the moist. White jade is a natural product, and it is difficult to have a uniform physique, including jade tendons and jade flowers.

If the glass is artificially made, there is no such appearance. The white jade texture is firm and there are no bubbles to be found. No matter how well the glass is processed, there are often bubbles and air holes exposed.

If you figure out these items, you won't think of glass products as jade.
