Catalogue entry no. 23 by Max Loehr:
Small specimen of a partly translucent, greenish and brownish jade in an advanced stage of calcification. The shape compares with No. 22, but the segments removed are larger, so that the cutting edge is accordingly shorter. The perforation was drilled from one side, its wall slanting strongly. This conical hole harmonizes with the beveled edge of the splayed area below the “teeth.” The teeth are carved out in a rhythmic, symmetrical pattern, with beveled interstices above and below the central pairs. Shang or early Western Chou.
