Catalogue entry no. 320 by Max Loehr:
320 Pair of Ring Sections with Cicada Ornament
Gray-green and cream-colored jade arcs, each shorter than half a circle, derived from a broken ring with partial flanges. On the exterior faces of these sections are very elongated, engraved cicada figures, whose heads lie between the flanges. The ends of both pieces are shaped like fish tails. The tips of the noses are perforated. Probably Western Chou.
