Jade

Hotan Jade, one of the "Four Famous Jade in China", refers to the jade produced in Hotan, Xinjiang in the traditional narrow sense, and is famous for its "sub materials"; In a broad sense, Hotan Jade refers to nephrite (genuine jade). Although Hotan Jade is named after Hotan in Xinjiang, it is not a regional concept in itself, not specifically referring to the jade produced in Hotan, Xinjiang, but the name of a class of products. China names the stones with tremolite composition accounting for more than 98% as Hotan Jade, all within the national standard range. [1-6]
When the First Emperor of Qin unified China, Hotan Jade was called "Kunshan Jade" because it was produced in Kunlun Mountain, and later it was called "Khotan Jade" because it was located in the territory of "Khotan State". It was not until the establishment of Hetian Zhili Prefecture in the ninth year of the reign of Emperor Guangxu of the Qing Dynasty (1883) that it was officially named "Hotan Jade".
