Emerald is a kind of jade introduced to China in Ming and Qing Dynasties. Later, because of Myanmar's submission, it really entered the historical stage of China. Since then, due to the love of Empress Song Meiling and others for jade, it once became the favorite of celebrities from all walks of life. Now it has a history of more than 400 years in China.

The formation of jadeite mainly needs to go through three stages, namely diagenetic stage, jade-forming stage and optimization stage. In these stages, jadeite is slowly formed because of the strong movement before each plate, and jadeite needs extremely harsh external conditions. Only in the environment of low temperature and high pressure can the internal structure of jadeite become denser, and at the same time, the chromogenic ion chromium is needed to enter, and jadeite will gradually form green, thus becoming a real jadeite.
