What is a variant? Do you know how important the species of jadeite is?

1: Accurately identify the quality of jadeite. Friends who have practical experience can quickly identify whether it is medium-aged and medium-tender. The quality of the jadeite should be considered based on the coarseness of the flesh, transparency and its density. The cross section of loose structure is very rough, and there will be many spots.

Some of them look tender in texture and have long water heads, but the seeds are very tender. These are called "tender holes", and it looks like there is no difference between skin and meat. The reason for this posture is that the structure is loose, the density is not good, and the crystal gaps of jadeite are relatively large. The tender and hollow material looks beautiful, but it is difficult to polish it during the processing. After wearing it for a long time, it will become very dry, and some of it will turn yellow. Due to lack of water, the color becomes lighter and more dilute.

How to identify the variants of stone? If you only identify it by cross-section, many friends can tell it apart, but it is not easy to distinguish whether the entire material has a variant.

It is mainly analyzed from various aspects such as skin, sand, field, etc. If the whole shell is relatively uniform and smooth, then its sand grains are also uniform. We can judge the possibility that there is no variant in this area. Otherwise, the possibility of mutation will be very high.
