1, photo: With a flashlight or in natural light, the front of the jadeite stone is easily exposed. The natural jadeite stone is gorgeous and natural, in which the green direction is very clear and the luster is strong.

2, look at the shell: jadeite original stone shell mainly has three categories: sand skin, fine skin and coarse skin. The fine skin is the best, the particles are very fine, and the texture of the cut jadeite raw stone is also excellent; The fake jadeite original stone has no naturally arranged fine particles in its shell; In addition, the shell color of natural jadeite stone is very pure, while the color of fake jadeite stone is unclear and its luster is very poor.

3. Look at the structure of the jadeite original stone: jadeite may be soaked by strong acid or alkali, and some substances after corrosion will remain on the jadeite original stone, and meat jade will dissolve with these chemicals, resulting in internal connected cracks, so it can be seen that the jadeite original stone has staggered cracks under the illumination, and at the same time, under the condition of reflected light, the corrosion pits or spider network lines on the surface are clearly visible. But in any case, even the natural jadeite stone is not worth starting with if there are too many cracks.

4. False color: If you see some burning focal spots of different sizes on the shell of the original jadeite stone, it may be that the original jadeite stone has been baked.
