NORTHWEST CHINA, NEOLITHIC PERIOD, 2ND MILLENNIUM BC

The dark green, semi-translucent stone of this disc appears to be similar to that of a disc from Shanxi province, Longshan culture, c. 2000 BC, illustrated by Jessica Rawson in Chinese Jades from the Neolithic to the Qing, British Museum, 1995, p. 152, fig. 4. The size of the disc and size of the central aperture are also similar.
