What does hetian jade think of quality?

Hetian jade can be judged by color, texture and structure.

1, color

Color is an important basis for Hetian jade to be different from other jade. Hetian jade can be divided into white jade, sapphire, sapphire, topaz, jasper and jet by color. Among them, white jade has the best quality, suet white jade is the best, and jet jade has a low value, which belongs to the next category.
