Catalogue entry no. 535 by Max Loehr:
535 Ornate Disk
This disk, made of dark green jade with light brown and russet spots, resembles the preceding type in that the décor is arranged in two concentric zones divided by a rope-ring, but differs with regard to the design of the outer zone. Instead of the “bucraniums” there appear, on both sides alike, three bird figures, elongated and in sweeping curves, executed by incisions and heavier grooves. The neatly carved hexagons are left plain. The perforation is unusually small and slightly conical. Western or Eastern Han.
