A very common variety in the Emerald family, referred to as the bean variety. The name of the bean is very large; the crystal grains of the bean species are mostly short columnar, and the grain beans are arranged inside the jadeite. The interface of these crystals can be clearly seen by the naked eye. Due to the coarse grain, the appearance of jade pieces is inevitably rough, and the gloss and transparency are often poor. The jade business called it “dryâ€. Bean species are middle and low-grade varieties in jade, and the price is not high. Bean seeds can be subdivided into coarse beans (grains larger than 3 mm), fine beans (grains less than 3 mm), jelly beans and ice beans.
In the old days, the business said that the jade has "36 water, seventy-two beans", which refers to a wide variety of jade, and not as many as 72 kinds of jade.
