Catalogue entry no. 532 by Max Loehr:
532 Ornate Disk
The disk, made of warm gray translucent jade with russet markings and dark brown, nearly opaque areas, bears a décor composed of two zones separated by a distinctly rope-like circle, similar to disk No. 530. As in the latter, the outer zone shows the “bucranium” motif repeated four times, although it is executed here in a coarser and more angular manner. The design of the inner zone, however, consisting of a concentrically arranged pattern of engraved, paired spirals which increase in size in proportion to their distance from the center, is quite unlike the hexagon patterns of Nos. 530, 531, and the large disk No. 533. The décor is identical on both sides of the disk. The perforation, strongly conical, was drilled from one side. Western Han(?).
