Rubbing the stone in the right position is effective and safe. When rubbing the jadeite raw stone, the main thing to look at is the fog, bottom and color on its skin. The polishing of jadeite raw stone is not done randomly, but requires certain skills and techniques. Generally speaking, the order of polishing jadeite raw stone is to polish the roughness first, then polish the dryness, then polish the dinginess, and finally polish the looseness.

2. Grindstone

The purpose of grinding jadeite raw stone is to polish it, which can show the transparency of the texture, so that its color and water quality can be clearly seen. Grinding stone is also the most popular way to cut jadeite raw stone, and the purpose of grinding stone is to see the texture and color of the jadeite clearly. If the hand shakes or the stone is not seen clearly, it will be ruined if it is ground too hard, so grinding stone also requires particularity. But stone cutting is different. It is the most critical step in the raw stone and it is also the moment to witness miracles.

3. Stone cutting

There is a primitive cutting method, which is to use a bow saw to press the sand and slowly saw the jadeite raw stone. If it is found that cutting cannot continue, it is convenient to take rescue measures. Another method is to use a jade cutting machine with a diamond-coated blade. The cutting is accurate and fast, but the jadeite raw stone is clamped in oil or water and it is not easy to see the cutting process. Only when it is completely cut open can you know the outcome. If the jadeite raw stone is too large, an oil saw is required.

When cutting a stone, the first thing to do is to find the right part. Generally, you can cut from the rubbed edge or from the shavings. You can also cut from the loose flowers of the jadeite or along the cracks. When the color is gone after the first cut, you can cut the second and third cuts. One cut makes you poor, and one cut makes you rich. This is what it means.
