The cuboid is made of translucent green jade. The profile is rectangular prism, and its upper part is larger that the lower part and its surface have 10 nodes and grooves. On every corner of the nodes is a simplified human face: round eyes, broad nose, and narrow mouth. On the upper part of one side was carved a human–shape sign. The entire object showed fine craftwork with the feature of well-polishing from inner part to the outside, and the quality of jade is smooth. This jade cuboid is identical with jade cuboids of the late period of Liangzhu culture in structure, pattern and workmanship.
