新石器時代良渚文化 黃玉琮

the attractive yellow stone mottled with russet, skilfully worked and smoothed in the form of a vessel with  plain rectangular sides and a cylindrical shaft

As visible in the catalogue photo, there are tiny nicks to the corners and vertical sides of the vessel. The circular mouth and foot are slightly irregular, possibly with minor smoothing down, but also where natural flaws of the stone were exposed in the original carving process. There is other minor surface wear and scratches. The colour is slightly less of a vivid yellow than in the catalogue photo.

The Liangzhu culture (3400-2250 BC), the Neolithic jade culture in the Yangtze River Delta of China, was highly stratified, with jade, silk, ivory and lacquer found exclusively in elite burials while pottery was more commonly found in the burial plots of poorer individuals. The jade from this culture is characterised by finely worked large ritual jades. For another Liangzhu culture jade vessel sold at auction, see a ritual huang sold in these rooms, 8th April 2013, lot 3014.
