499 Disk Pendant
Translucent, light brown jade disk with a slightly corroded edge and opaque areas. The disk, which has a small cusped projection with a tiny perforation, is decorated with modeled curls densely arrayed on a grid. An openwork inner ring is carved free except for three radial bars that join it to the disk; the only decoration on this ring are three incised double curves. Late Eastern Chou.
