The disc is finely carved, the surface on both sides smoothly polished. The stone is slightly translucent when held against the light. It is of unusually large size. There is a crack running along a natural fissure in the stone from the inside rim of the disc to the exterior rim, ca. 10.5cm in length and visible on both sides, with an associated vein/fissure running ca. 7 across on both sides. One one side of the disc there is a ca. 0.5x0.5cm wide shallow chip to the edge on one notch (visible in the lower right hand side in the catalogue illustration). There is a small ca. 0.3cm wide chip to the tip of one notch (visible at ca. 3pm in the catalogue illustration). There are traces of a leiwen pattern between two dark stains on one side of the disc (visible at ca. 7 and 8pm in the catalogue illustration) and two finely incised straight lines crossing a third finely incised straight line on one side (visible in the catalogue illustration).

Discs feature prominently among jade artifacts recovered from sites of the Neolithic period to Han dynasty. Among them, notched discs form a small but distinctive group. Defined by the deep notches that divide the circumference into segments, the earliest examples have been found in late neolithic sites on the east coast in Shandong province and in the west in Shaanxi province. For an overview on the development of notched discs, see Jessica Rawson, Chinese Jade from the Neolithic to the Qing, London, 1995, pp. 160-162.

On the present disc, one side shows a series of straight horizontal and vertical lines that have been incised with great precision. Similar incised lines also appear on a notched disc formerly in the K.C. Wang Collection, famoulsy reproduced in a line drawing in Wu Dacheng's Gu Yu tu kao, Shanghai, 1889, p. 50, left. In the accompanying text, Wu Dacheng identifies notched discs as xuanji based on a reference from a text from the Shu jing.

The present disc is unusually large and no other jade notched disc of this size seems to have been recorded. A much smaller disc excavated from Lizhuang, Teng Xian, Shandong, attributed to the Longshan culture of the neolithic period (ca. 2500-2000 BC) shows a closely related profile. Like the David-Weill disc, the excavated disc is carved from a softly polished matte grey jade stone, the notched outline further enhanced with small series of teeth, compare Zhongguo yuqi quanji, vol. 1 (Neolithic), Hebei, 1992, no. 42. Few other if smaller examples have been excavated, yet several more have survived in collections formed at the same time as the David-Weill Collection in the 1920s and 1930s. A disc formerly in the Eumorfopoulos Collection, London, and acquired by the British Museum in 1937, is carved of the same greyish white stone, see Soame Jenyns, Chinese Archaic Jades in the British Museum, London, 1951, pl. X.
