Description: Jade. China, Late Neolithic period, early Bronze age, c.2000 BC This fine disc is carved from translucent green jade which in some points gets darker and almost black. One third of the disc is strongly altered: here, the jade has turned whitish, with a large patch of orange-yellow colour. The disc is even in thickness, with smooth borders and the hole was drilled from both sides. The type of jade and workmanship suggest that this disc was produced in the transitional phase between the Neolithic and the Bronze Age. The stone differs from that usually associated with the late Neolithic cultures of North-west China, such as Qijia, since it is more shiny, even when the light hits the surface without passing through the jade. It is thus possible that the disc was crafted in other regions, such as Shaanxi, or in sites associated with the Taosi culture (c.2300-1900 BC) in Xiangfen, Shanxi province. A disc carved from green jade (diameter 22 cm) and from the Joseph Hotung collection is illustrated in J. Rawson, Chinese Jades: from the Neolithic to the Qing, London 1995, no.7.6.
