5. "Hetian jade" is dry.

He Hotan used to be in Hotan, and he was whatever he said. I don't know why, but now I know the situation.

Hetian jade: Hetian jade is one of the four famous jade in China (followed by lantian jade, dushan jade and Xiuyu), which is divided into "narrow sense" and "broad sense". The traditional concept of "narrow sense" refers to the jade produced in Hotan area of Xinjiang, which is famous for its "inferior material". Hetian jade in a broad sense refers to nephrite (real jade).

When Qin Shihuang unified China, Hetian jade was called "the jade of Kunshan" because it was produced in Kunlun Mountain, and later it was called "Yutian jade" because it was located in the kingdom of heaven. It was not until the establishment of Hotan Zhili Prefecture in the ninth year of Guangxu in Qing Dynasty (1883) that it was officially named "Hotan Jade".

Hetian jade is a metamorphic rock formed by the contact between magnesium marble and intermediate-acid magmatic rocks. Gemmology in China points out that the Mohs hardness of nephrite is 6.0-6.5, and jade with tremolite content above 98% is called Hetian jade, which contains tremolite, hornblende, actinolite and other mineral aggregates. The chemical composition of Hetian jade is hydrated calcium magnesium silicate, the chemical formula is CA2MG5 (OH) 2 (Si4O11) 2, and the density is 2.95-3. 17.
