Chinese jade art

Chinese jade refers to the jade mined or carved in China from the Neolithic onward. It is the primary hardstone of Chinese sculpture. Although deep and bright green jadeite is better known in Europe, for most of China's history, jade has come in a variety of colors and white "mutton-fat" nephrite was the most highly praised and prized. Native sources in Henan and along the Yangtze were exploited since prehistoric times and have largely been exhausted; most Chinese jade today is extracted from the northwestern province of Xinjiang.

Jade was prized for its hardness, durability, musical qualities, and beauty. In particular, its subtle, translucent colors and protective qualities caused it to become associated with Chinese conceptions of the soul and immortality. The most prominent early use was the crafting of the Six Ritual Jades, found since the 3rd-millennium BC Liangzhu culture: the bi, the cong, the huang, the hu, the gui, and the zhang. Although these items are so ancient that their original meaning is uncertain, by the time of the composition of the Rites of Zhou, they were thought to represent the sky, the earth, and the four directions. By the Han dynasty, the royal family and prominent lords were buried entirely ensheathed in jade burial suits sewn in gold thread, on the idea that it would preserve the body and the souls attached to it. Jade was also thought to combat fatigue in the living. The Han also greatly improved prior artistic treatment of jade.
