During the Shang dynasty (1600–1046 bce), they began making small ornamental plaques with decorative designs of animals incised on them in low relief. Jadeite does not appear to have been worked by them until the 18th century ce, when large quantities of that jadestone began entering the country from Myanmar via Yunnan province.Īs early as the Neolithic period the Chinese were carving jade into tools and simple cult objects in the form of flat disks with circular orifices at their centre. For millennia the jade carved by the Chinese consisted of nephrite from the region of Hotan (Khotan) and Yarkand in what is now Sinkiang. Jade and jade carving are associated preeminently with China, since in no other region of the world has this obdurate material been worked with such skill in such a long and unbroken tradition ( see Chinese jade). When the stone-based Neolithic cultures were succeeded by ones using bronze and iron, however, jade gradually lost its industrial value and fell from favour as a gemstone in all but a few regions. Jade is hard, tough, and heavy, and it takes and keeps a good edge, while its fine colours and warm polish must have greatly appealed to Neolithic craftsmen. The best-known finds are from the lake dwellings of Switzerland, western France, Central America, Mexico, and China. Carborundum and diamond dust have replaced crushed garnets and corundum (emery) as abrasives.īoth jadestones were worked into implements by Neolithic peoples in many parts of the world. Over the course of history, jade has been successively cut and shaped with sandstone, slate, and quartz sand (as an abrasive) by tools made of bronze by tools of iron, using manually operated lathes and finally, beginning in the 19th century, by machine-powered lathes, steel saws, and diamond-pointed drills. Occurrences of nephrite are more numerous and geographically more widespread. The area around the city of Mogaung in northern Myanmar (Burma) has long been the main source of gem-quality jadeite. There are also wide variations of translucency in both stones. Some colours are also peculiar to one stone or the other for example, the popular apple- and emerald-green jewelry jades are invariably jadeite. The fine lustre of polished nephrite is oily rather than vitreous (glassy), while that of jadeite is the reverse. The two different types of jade, when worked and polished, can usually be distinguished by their appearance alone.
