What is the opening of the jade?
In order to show the color and texture of the interior of the jade seed material (large gravel block), it is generally in the place of the skin, depending on the size or needs of the stone, using a special tool for cutting jade stone, that is, one can be rotated by electricity. The large metal disc) cuts a flat hole called "opening the door", also called "opening the sky window".
After the seed material has opened the door, you can observe the "meat" of the jade from the door to increase the base of the heart when the buyers and sellers or the jade designer design works.
However, opening a door is not necessarily very reliable. Because the door can only reflect the local phenomenon inside the seed material, for example, the green of some seed materials is only concentrated near the outside, the jadeite will open the door at the skin. If the buyer is not good at identification, it will definitely suffer losses. In recent years, the jade business has a variety of means to fake the door, and it is impossible to prevent it. Buyers who are involved in the jade market should gradually accumulate experience in order to purchase boldly, otherwise it will be difficult to avoid fraud.
