Jade, also known as jadeite, jadeite and Burmese jade, is a kind of jade. The correct definition of jadeite is fibrous aggregate composed of pyroxene minerals, mainly jadeite minerals. But jade is not equal to jade. Jadeite is a polycrystalline aggregate of stones formed under the geological action and reaching the jade level.

Extended data:

Emerald belongs to pyroxene, monoclinic system and two groups of perfect cleavage. The main component is sodium aluminosilicate NaAl9(Si2O6), and a gem is regarded as jadeite only if it contains more than 50% sodium aluminosilicate. It occurs in metamorphic rocks generated at low temperature and high pressure.

The mining, transportation, processing and sales of jadeite have always been done by Yunnan people. In an ancient Chinese temple in Amoluboro, the ancient capital city of Myanmar, the names of 5,000 jade merchants in China are engraved on the inscription, which is also introduced in jade margin and jewelry. In the middle of the Ming Dynasty, senior eunuchs stationed in Tengchong, Baoshan, specializing in purchasing jewelry. At that time, the route from Yongchang Tengyue to Myitkyina, Myanmar, had been called "Jade Road" and "Baojing Road".
