How to choose a good piece of jade rough material

Jade rough materials are difficult to identify, mainly because they have a thick skin, and the opening and polishing cannot fully represent the quality of the entire raw material. Therefore, when purchasing, one should study the incision and the whole piece of jade to determine whether there is green, the possible direction of the green, the amount of green, the concentration and dispersion of the color, as well as the color's positive, dark, light, positive, length of water and the number of cracks. But it is best to pay according to how much green you see. If there is no green, the water should be good. When the water is good, you should check whether there are cracks and impurities. Think of the worst when purchasing raw materials. Think about what to do if you lose money.

How to choose a good piece of jade rough material? These points must be remembered -

1. When rubbing the large jade raw material, be careful when green appears on the edges. When the skin performance is average, it should be purchased at the standard of low-priced brick materials.

2. The green color of the jade raw materials' laid edges, broken edges, cut edges, and rubbed edges is good, but be careful when not polishing them. Such materials often have many cracks, gray bottom, irregular green color, poor water quality or black inside the green, so they are not polished.

3. Before inspecting jade materials, especially high-end jade materials, the owner will leave many traces of friction and digging when looking for green on the jade materials. These traces are some green-free areas. If a piece of jade has traces of green everywhere, be careful when looking for them.

4. When a large area of ​​green can be seen on the cut of jadeite, it is called full green, so be careful. There is a saying among the people, "I'm not afraid of a line, but only of a large area" (referring to green). This large area is often caused by a cut along the direction of the green, that is, parallel to the direction of the green. The actual thickness is only a thin layer.

5. If a piece of the jade raw material has been cut, you must study that small piece carefully when purchasing it. Observe the gap between the two pieces to see if the green has the possibility of extending to the larger piece of jade.

6. The quality of raw jade produced in Myanmar varies greatly due to different origins, so it is necessary to master the characteristics of the jadeite's origin.

7. When purchasing raw jade, you should look for ringworm, scales, and loose flowers on the jade skin. These manifestations indicate that green may be produced under the skin.

8. When purchasing full green materials, you should understand the impact of the quality of water on the finished product, otherwise you may not be able to make a profit. If light can penetrate a few centimeters into the jade raw material, the green will be crystal clear, beautiful and very transparent, but it cannot be made into a high-end ring face. If it is made into a ring face, the green may be light green or even colorless. Therefore, it is necessary to master the relationship between water and green. Generally speaking, at noon, the amount of sunlight that can penetrate into the cut jade is about 6 to 3 mm. The thickness should be used to adjust the optimal thickness of its water color.
