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. With gold, it was considered to be a symbol of heaven. Jade production began in China over seven millennia ago (c.5000 BCE), yielding the largest body of intricately crafted jade artifacts created by any single civilization. A prominent early use was the crafting of the Six Ritual Jades, found since the 3rd-millennium BCE Liangzhu culture: the bi, the cong, the huang, the hu, the gui, and the zhang. Since the meanings of these shapes were not mentioned prior to the eastern Zhou dynasty, 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.
These uses gave way after the Three Kingdoms period to Buddhist practices and new developments in Taoism such as alchemy. Nonetheless, jade remained part of traditional Chinese medicine and an important artistic medium.

thumb|Cong issu du site archéologique de JinshaEn archéologie chinoise, le terme Cong (chinois: 琮; pinyin: cóng) désigne un objet de jade sculpté, de forme tubulaire, datant de l'âge néolithique. Les plus anciens datent de la culture de Liangzhu (3300-2000 AEC), qui en a produit en grand nombre. On en trouve encore sous les dynasties Shang et Zhou. Sa spécificité réside dans l'imbrication de deux formes : sa section externe est carrée mais sa section interne est ronde.

La glyptique (du grec ancien γλυπτός / glyptós, « objet gravé ») est l'art de la gravure des pierres fines, comprenant la taille, et de la sculpture en creux (intaille) ou en relief (camée). Elle exprime le plus souvent des sujets tirés de la mythologie, des religions ou de thèmes culturels ou symboliques. Ce terme est souvent employé pour désigner l'art de tailler les sceaux-cylindres en Mésopotamie.
