How should a novice cut jadeite rough stone?

When cutting jadeite rough stone, you must know the position of the jadeite rough stone very well. Although jadeite rough stone can be polished and grinded, "polishing the stone does not count as an increase in value, only cutting it counts as an increase in value." Therefore, you must cut it very accurately. If you are not careful, you will cut the green in the rough stone. Therefore, you must have a deep understanding of the jadeite rough stone and know the position of the rough stone. Cutting a stone is also a technical job. Cutting is not just about cutting the jadeite rough stone into two halves. The position of the knife must be accurately determined, and the surface crack cutting, how many cuts to make, etc. must all be carefully considered. Otherwise, maybe the jadeite rough stone you bought would have increased in value, but it was really "cut" across because of such a willful and capricious knife.

There is a saying in the jade industry: "Polishing the stone can make you rich, but cutting the stone can determine life or death!" By wiping off the skin of the stone before cutting it, you can better observe the internal condition and help determine where to cut. But there is also a saying on the other side of this sentence: "Rubbing the increase does not count as an increase, only cutting the increase counts as an increase."

The so-called cutting refers to the first cutting of jadeite. After such cutting, we have a general understanding of the original stone. But the cutting is not deep, it is only used for observation and judgment, and then to choose a good direction to cut, but it is also necessary to observe and analyze carefully before making a decision. If the original stone has cracks, the first cut should be made from the cracks. When cutting, you must make good cutting marks. If it is a good quality material or color material, a deviation of a few millimeters will result in a loss of more than a few hundred yuan. Especially for the color material, you must be especially careful and cut from the worst place, following the principle of original stone green.

.

After we have made the markings, we can start cutting the raw stone. Until most of the skin of the raw stone is removed and the jade in the entire raw stone is exposed, each step of cutting must be done in place and no carelessness is allowed. This is a difficult process that tests one's technical level. If the cutter is not careful, the sharp cutting machine in the hands of the jadeite will damage the higher quality parts of the jadeite. Therefore, certain skills are required in cutting the raw stone. How to cut and where to cut require careful consideration before starting to use the knife.
