Specific introduction

When you get an ancient jade, you should first judge whether it is jade or stone, and then judge the category and origin of the jade. According to experts' research, the vast majority of jade materials used before Shang Dynasty in China are local jade materials collected nearby, among which serpentine (Xiuyan stone) jade, quartzite jade and serpentine marble are typical and extensive, as well as dushan jade in Nanyang, Henan and Hetian jade in Xinjiang.

Hetian jade has been widely used in ancient jade articles since the late Shang Dynasty, especially in the Spring and Autumn Period and the Warring States Period. All the famous products or ornaments with particularly exquisite workmanship in the above historical periods must be excellent Hetian jade. Therefore, we should first judge ancient jade by the times, and the characteristics of the times are called a basic method to judge jade.

For example, an ancient jade product before Shang Dynasty was made of Hetian jade, which may be a "lie". For another example, a well-made Warring States jade is made of low-grade miscellaneous jade or colored stones, and there are some strange things in it, which requires you to have as much historical knowledge as possible.
