How to distinguish the quality of jade and its classification?

Method of jade separation: Look, it 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 passed through the glass, leaving scratches on the glass, while the jade itself was intact.

The common fake jade includes plastic, stained glass, marble, electro-colored fake jade, jade powder and synthetic jade made of crystal salt water, and their identification methods are also 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 them spider claws. It is also said that if the electro-colored fake jade is put in hot oil, the electroplating color will fade and restore its true 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 the proportion of synthetic jade is only 2. 8。 Weigh by hand, or use a 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, and it must be high. That is, white jade should be as advanced as nitrate. It can be seen that nitrate and jade are difficult to distinguish. However, the facts are different after all. As far as color is concerned, white jade is often blue, and white is rare, while nitrate is pure white. As far as jade is concerned, jade is moist and delicate, as fat as cream. Nitrate is wet, but there are thieves in it. White jade is a natural product, and it is difficult to have a unified structure, including jade ribs and jade flowers. If nitrates are manufactured artificially, there is no such appearance. White jade has a solid texture and no bubbles can be found. No matter how well nitrate is treated, bubbles and pores are often exposed. If you know these items, you won't regard nitrate products as jade articles.

How to see the fineness of jade: there are too many kinds of jade, and the identification methods are different. At present, there are many jade ornaments sold in the domestic market, and jade is also a kind of jade. Let me briefly tell you about jade.

Listening to the sound is on the one hand, mainly depending on the fineness of jade, which is rough and abrasive. Although jade has beautiful quality, it lies in stone, which is not worth pondering, unlike gravel. The truth of these old sayings is that good materials are only the basis for making jade articles, and its value can only be finally reflected through artificial design and carving. The quality of jade work is an important factor to determine the grade of jade. A good jade should have a beautiful and harmonious composition, exquisite craftsmanship and a warm and greasy feeling on the premise of using good jade materials. In addition, the age, historical function, the identity of the possessor and the unique shape of jade works often affect the value of jade.

The name jade itself is related to medicine and comes from Spanish. Jade contains many trace elements such as selenium, zinc, copper, cobalt and manganese. When worn on the body and in contact with the human body for a long time, these beneficial elements will be gradually absorbed by the human body, so that various trace elements in the body can be supplemented, which plays a role in eliminating diseases and strengthening the body. In addition, jade also has the functions of stabilizing emotions and enhancing people's quick response ability.

China is called the land of jade. As early as 5000 BC, during Hemudu culture, jade wares such as Jade Emperor and Jade Beads appeared in China, which is the oldest jade culture in human history. There are records in ancient books such as Shangshu, Shan Hai Jing and Gong Yu. It is said that in ancient times, Huangdi, the ancestor of the Chinese nation, gave jade to tribal leaders as a symbol of power. Many emperors' seals were also carved with jade. The story of Heshibi in history is the cultural embodiment of the spirit of worshipping jade in ancient rivers and fires.

Jade has a profound relationship with China culture. Some people even divided a jade age in the history of China between the Stone Age and the Bronze Age, which also made sense. In the history of thousands of years of civilization, a material culture can spread for thousands of years, and the only thing that has not been interrupted so far, except ceramics, is probably jade.

There are many origins and varieties of jade in China, such as Hetian jade in Xinjiang, Yili jade, Xinyi jade in Guangdong, xiuyan jade jade in Liaoning, Shandong jade in Shandong, Yuchuan jade in Shaanxi and Miyu jade in Henan. The highest quality jade in China belongs to sheep fat jade in Hotan, Xinjiang. It is white in color, delicate in texture, compact in structure, firm but not brittle. People in China believe that wearing jade can not only play a decorative role, but also achieve the effect of fitness, as well as the meaning of wishful thinking, longevity, peace and auspiciousness

Emerald has won the reputation of the king of jade with its luxurious, deep and steady character and irreplaceable advantages. Its advantages and disadvantages should be viewed from four aspects: color, transparency, shape and impurities.

Color-color is an important link to determine its value. It must be bright and even, and it must be positive.

Transparency-Good jadeite has good transparency and fine texture. Green and dark green have a sense of transparency, such as clear spring water, which is endowed with luster and good moisture retention.

Shape-the shape, size and thickness of jadeite should be appropriate, and the grinding thickness should be uniform.

Impurity-whether the texture is clean or not and whether it contains impurities determines the quality of jadeite. Emerald can't have black spots, spots, cracks and flower marks.

How to tell the quality of jade?

1, the historical value of jade

Emerald is divided into 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 carver. Some technical contents were also involved before. However, the identification of Lao Yu is unusual. In addition to several basic requirements, new jade also needs to know the production age and historical value of jade. Familiar with the common shapes, characteristic crafts and popular colors of jade in different times.

2. Look at the process to distinguish jade

Sculptor Hong Wenyong once said that a good horse needs a good saddle, just as a master has a high demand for rice paper when painting, and will not paint on cheap rice paper casually. Good rice paper will make the work look comfortable. Carving jade is the same, and sculptors will not waste good jade easily. Good jade is hard to find. Generally, only a small amount of jade is available on a large stone, and the coolies who are beginners in carving jade dare not practice it easily. Therefore, for people who want to collect jade but don't understand it, the easiest way to judge the quality of jade is to look at the craft of this jade first.

3. Look at Jed

Good jadeite jade should have boldness of vision. Even if it is only a little green, you can feel its color from a distance. If it is not a good jade, it will turn black. It is not enough for jadeite to be transparent, but also the particles overlap. White jade is called nephrite because the particles inside are spun silk.

2. Touch by hand
