Looking at the current jade market, we can find that there are various types of jade, but there are many poor quality jade, so how to identify the quality of jade is a very concerned issue. How to judge the quality of jade? "Jade" is an indispensable part of Chinese culture, as early as thousands of years ago, the production and use of jade has begun, and jade has been passed down to the present in the current of advancing history.



Looking at the current jade market, we can find that there are various types of jade, but there are many poor quality jade, so how to identify the quality of jade is a very concerned issue. How to judge the quality of jade? = In fact, you can identify according to the texture, color and luster of jade, but remember that there are many jade materials that can make jade in the market, and different jade materials, their characteristics are different. Therefore, we can not generalize when identifying the quality of jade, we must first make clear what type of jade they choose, and then identify the texture, color and luster of the selected jade.

Take the jade made of Hetian jade for example. The good hetian jade jade is white in color, delicate and warm in texture, and the luster on the surface is strong grease gloss. The overall look is oily and smooth and very delicate. The following 6 standards, let's analyze the ~01 color, must be pure and uniform. Hetian jade is rich in color, according to the color can be divided into: white jade, blue jade, topaz, sugar jade, black jade and other types, but no matter what the color, it must be pure and uniform, the so-called white such as condensed fat, yellow such as steamed chestnut, green such as lichen, is this meaning.

02 Structure, must be close and delicate. What is structure? It is the grain size, form and so on of jade mineral. To see whether this hetian jade is good, the structure is very important, good hetian jade texture is close and fine, the naked eye can not see particles, water lines, etc., on the contrary, loose texture, the quality is not good. 03 luster, must be delicate and moist. Hetian jade has grease luster, glass luster and waxy luster. Grease luster is the best, which can make jade more warm, delicate and moist, giving people a very comfortable feeling.

The second is the luster of glass; Poor waxy luster. Quality of a material is better, burnish feeling is stronger, conversely, quality of a material is bad, burnish is weak also. When the texture of Hetian jade is relatively poor, it will appear waxy luster, and according to the special processing technology, it can also show glass luster or waxy luster. Clarity, the fewer defects, the better. Clarity, commonly known as jades in Hetian jade, is the manifestation of jade defects, including cracks, impurities, inclusions, etc. In the gemstone industry, it is often called a flaw.

The spots in Hetian jade are mostly caused by impurity minerals contained therein. Natural jade inevitably blemish, have stone flower, black dot, tuft crack and so on. Good Hetian jade, the fewer defects, the better. Transparency, opacity is not good, too transparent is not necessarily good. Mineral transparency is generally divided into three types: transparent, translucent and opaque. In the jade industry, the transparency of jade is also very important, and there are common words to describe the transparency, such as the good transparency is called "earth son spirit" or "pit spirit", "water head foot"; The transparency is poor called "the ground is stuffy", "the pit is stuffy", "no head".

Because the transparency of jade plays a role in setting off the texture and color of jade, it is more aesthetic, so the same material with water head and foot is better. However, water head foot is only relatively speaking, opaque is not good, too transparent is not necessarily good. The transparency of first-class Hetian jade is not high, but the transmittance is good, such jade material has the warmth and moistness of Hetian jade, and it is the most rare collection grade Hetian jade.

But the number of such jade is relatively small, the most common material is not dry Russian material, is very high transparency of Qinghai material, the collection value is more general! Craftsmanship should fully reflect the perfection of jade. The quality of the process directly determines the price of the finished products of Hetian jade, which is called "three raw materials and seven divisions of labor". Good jade material must have good technology to fully reflect the perfection of jade.
