WORLD HISTORY

Detailed explanation-1: -Jade is a term used to describe two different silicate minerals-jadeite and nephrite. Jadeite is a sodium-aluminum silicate rock with a polycrystalline structure. It belongs to a group of rock-forming minerals called pyroxene (which includes minerals such as diopside and spodumene).

Detailed explanation-2: -There is evidence that jadeite jade, coming primarily from Burma, began to be traded in China on a wider scale in the 14th century. It was harder, denser, and worked easier – it eventually became the form of the gemstone preferred by Chinese artisans and prized by the Chinese people.
