1, jade bracelet, with the current production process, generally there will be no uneven polishing. The reason for uneven polishing of jade bracelets is professionally called mine shortage. It is because the jadeite germplasm is thick and the gap between crystals is large, which leads to the failure of polishing.

The hardness of jadeite is very high, which can only be compared with diamonds. With the current technology, if it is uneven, it is probably the material itself. Emerald belongs to pyroxene, monoclinic system, perfect cleavage.

3. Generally, the grinding and polishing steps of jadeite bracelets include drum rough polishing, thread trimming, smooth surface trimming and shaping. Put the carved jade into the drum with a grindstone.

4. The surface of jade is not smooth, so it can be polished by itself. The jade bracelet must have been processed, even if the surface is uneven, it is also a processing flaw, which is not too exaggerated. It is estimated that it is not smooth, and this situation is still easy to polish back.

5, jade polishing is uneven, in fact, you can choose to re-polish for processing. Generally speaking, jade ornaments will go through a process called polishing in the production process. Rough jadeite looks rough, the color is dim, and it is not moist at all. The polished jadeite has stronger stereoscopic impression, brighter color and more sufficient water head.

6. This is a defect caused by workers' lack of skills in cutting and polishing. It also shows that the material of this bracelet is not very good. There is no doubt that good jade materials will match good jobs.

Ask the master to identify why the jade surface is uneven, is it a processing problem or a material problem?

Poor germplasm and loose crystal structure lead to the shortage of ore, which is the problem of its own material. 2. The processing is not in place, resulting in small pits on the surface of the jade blank, which can be removed by re-polishing. This is a problem of processing technology.

No, because jade will be dense if it contains more heavy metals, but it can't be said that the quality of jade is good.
