Catalogue entry no. 70 by Max Loehr:
70 Pendant Shaped like an Arched Ko
Light grayish brown and cream-colored jade, slightly calcified and barely translucent. Possibly recut from a ring, the fairly sturdy small object retains the atypical bend. Its butt is recessed and perforated from both sides. Its blade is crested on the convex side only; its sides curve inward before reaching the point. Shang or Western Chou.
