Catalogue entry no. 325 by Max Loehr:
325 Huang, Disk Segment with Notched Ends
Fashioned of evenly light green translucent jade, the segment forms an arc of about 170 degrees. The ends are accentuated by carefully wrought notches. At either end, close to the notches, are single perforations. Both sides are decorated identically with configurations of two birds whose heads lie toward the ends and whose tails interlock in the middle. These birds, executed in sloping cuts and incised lines, are designed in long, flowing curves of an abstract nature, which closely resemble bronze decorations of Middle Western Chou date. On one side of the segment, the grooves of the décor are filled with earth and traces of cinnabar. Middle Western Chou.
