1. Emerald has been used since the Ming Dynasty. In the Ming Dynasty, there were frequent frictions and collisions between China and Viet Nam. At that time, Vietnamese monarchs would give jadeite as a tribute to the authorities in China, but there were not many jadeite tributes at that time, and the probability of its application was not great.

2. Later, in the Qing Dynasty, because Emperor Qianlong was very keen on jade, the jade at that time was more tribute, and the aesthetic concept of jadeite products changed greatly at that time, which was very clever with Chinese traditional culture and made jadeite enter the heyday of development at that time.

3. Later, because Cixi was almost obsessed with this kind of jewelry, compared with Qianlong, it was even too late. Cixi made this kind of jewelry into various finished products, even in life. It can be seen everywhere, so at that time, jade was regarded as the first jade, and gradually this name has been used until now.
