Catalogue entry no. 530 by Max Loehr:
530 Ornate Disk
Gray-green translucent jade with brown markings and flaws (to remove them would have led to an excessive thinning of the original slab). The disk shows two distinct zones of design, identical on both sides. The outer, wider zone is filled with four animal faces reminiscent of bucraniums; their large, staring eyes are partly outlined by a broad nose, terminated by a muzzle that spirals inward. The contours of the nose continue upward into convolute horns. Between the horns issue broad bands, each divided down the middle by an incised line and at regular intervals marked by slightly curved double striae. The bands bifurcate symmetrically to the left and right, bending down and going upward again. Where they bend, these bands are crossed by two shorter bands of a wing-like character. The much narrower inner zone is decorated with hexagons in relief, marked with engraved spirals. The two zones are separated by a circle striated like a rope. In contrast to the painstaking finish of the pieces listed before (Nos. 526, 527, 528, 529), the execution of this disk is almost rude. Western Han(?).
