The gambling stone in jade knowledge does not mean that buying materials is a gamble, and the result is entirely based on luck. Experts who are truly experienced and understand the knowledge of jadeite will have some signs of their appearance to judge the internal situation.
When observing jadeite raw materials, we must first pay attention to its outer skin characteristics, namely the color and tightness of the outer skin. If the skin is compact and delicate, it can be said that the texture of the jade is very delicate. If the outer skin is loose, the crystal inside the jadeite is relatively thick. If there are many small cracks on the surface of the skin, it can be said that there are many cracks and cracks inside the jade. Even if the raw material is cut very thin, it cannot be processed into a bracelet. Even if you take a step back and make a flower, you may not be able to make a larger, better quality flower.
