During the Second Opium War, the British and French coalition forces looted and burned the Yuanmingyuan. A large number of Hetian jade and jade jade articles were robbed to Europe. These things, regarded by the Chinese as treasures, caught the attention of the French mineralogist Demur, who conducted mineralogical analysis of Hetian jade and jade to identify their chemical composition and physical properties. He found that the hardness of Hetian jade and jadeite is different. So Hetian jade is called nephrite, and jadeite is called jadeite. Thus there is a definition of jade: jade is a cryptocrystalline aggregate consisting of two mineral nephrites and jadeite. This definition and the name of jadeite and nephrite are generally accepted.
Is jade jadeite? Some people say that jadeite is jadeite, or that jadeite is jadeite. In fact, these two statements are inaccurate. The so-called jadeite is a pyroxene mineral containing sodium and aluminum and is the main component of jadeite. But the "main ingredient" is not equal to all the ingredients, and the proportion of jadeite is not fixed. Especially in the jade of poor quality, the proportion of jadeite will become smaller, while the composition of other non-hard jade (such as albite, amphibole mineral) will increase. Therefore, we cannot say that "Jade is jadeite" or "Jadeite is jade". The correct expression is: Jadeite is a collection of various minerals based on jadeite.
Everyone should know that we understand here. The distinction between nephrite and jadeite in our mouth is from abroad, not from China. Although the name of nephrite and jadeite is well known to us, it does not mean that it is the most correct. On the contrary, in some respects, it obscures our perception and allows many unscrupulous traders to take advantage of it. Audiovisual, consumers should be cautious when purchasing.
