1, the quality of Zhengyang emerald is very high. No matter how you observe it in the sun, its color is relatively stable. This is because zhengyang jadeite mostly appears on beans and glutinous jade, and its texture is generally slightly transparent to opaque, so the light of zhengyang jadeite is not affected much, which is convenient for people to observe.

2. At the same time, it contains a small amount of jadeite minerals, but the content is uncertain, and there are amphibole minerals such as chromite. Gan Qing jadeite is actually a kind of sodalite, not jadeite. It contains only a small amount of jadeite, which is different from jadeite, so Gan Qing is not jadeite.

3. The green color of poplar is like fresh spring buds, clean and energetic! That is, the color is slightly transparent to translucent, the emerald is bright, and the yellowish color is bright, just like the new leaves of boxwood in early spring, so it is called poplar green or boxwood green. From this, we can see some characteristics of many green jadeites.

4. The jadeite in Gan Qing is rich green and pleasing to the eye, and its color is pure and flawless, which is almost the same as the jadeite with dark color, and sometimes it is dark black.
