I have a professional course on jade this year.

Let me give you a brief explanation. ...

I don't know whether the above is daily study or experience.

Or retrieve ...

There are two sayings about jadeite.

One is ancient China, referring to jade, which is explained in this way. There are five virtues in the beauty of stone.

It is different from the jade defined in mineralogy ... (in short, a beautiful stone is jade)

Second, since modern times, the West and China have made reference to jade materials (after China's jade spread to the West, French scholars first made a scientific determination of mineralogy, and formulated the so-called standards for jade to shine ...).

Basically, jade materials and jade articles are called jade now.

The classification of jade is controversial in academic circles. There are so-called nephrite, jadeite | jade, fake jade and semi-jade.

In fact, the popular sayings of nephrite and jadeite are not scientific.

Emerald is emerald.

Nephrite is Xinjiang Hetian jade, xiuyan jade jade and Golmud jade.

The hardness of jewelry is generally distinguished by Mohs hardness.

Mohs hardness of jadeite is 6-7, and Hetian jade is 5.5-6.5. In fact, some jadeites can reach 7.

Jade originated in Myanmar in the Qing Dynasty. Before it was loved by the people of China, it was presented to the court by Yunnan King Wu Sangui. Cixi especially likes jade.

But there are also a few in Japan.

The so-called distinction between nephrite and jadeite was also put forward by the Japanese.

Nephrite is also called Chinese jade.

So ... silently ... psychologically, it can be divided into soft and hard ... no one can say clearly. ...

After all, the difference in hardness is not so obvious.

But this statement is very common.

Just answered one.

Now ... just use it ...

See what else you know ... silently.
