Today, the editor will give you a detailed explanation: Hetian Yu’s eight levels are explained in detail!
1. White jade
Although all Hetian white jade belongs to the category of white jade, due to the different content of trace elements, abnormal structure and structure, locks, cracks, and impurities, different colors, textures, and glosses will appear.

7. sugar jade
There is often a "sugar color" (color like brown sugar) in Hetian jade. Sugar jade mostly belongs to subordinate status, so it is not divided into jade species separately. Because sugar color is mostly beautiful in jade carvings, it is very useful, so it is very popular. If "sugar color" occupies more than 30% of the jade, you can participate in the naming, such as: "sugar white jade", "sugar green white jade" and so on. If it is all "sugar color", it can be named "hetian sugar jade".
8. Red jade
This is a species that is basically extinct. Because it is extremely rare, it is not in the current classification. In ancient times, the classification mentioned red jade, white as fat-cut, yellow as steamed chestnut, black as lacquer, and red as cockscomb. Refers to the top grade in jade. There is an old jargon in Wanyu, "one red, two yellow, three ink, four sheep fat". Red jade is a gem of Hetian jade, but like the dragon stone species in jade, it basically only exists in legends.
