green and brown, much of this jade has a web-like pattern of greyish-white discoloration.
The outline of the disc is round with imperfections along the rim. The hole is small in
relation to the disc and was drilled from both sides with traces of the drilling still
visible. About 0.8 cm from the edge is an engraved motif 4.3 cm tall of a sacred
bird standing atop an altar. The lower part of the bird and the inside of the altar
are no longer visible and only the three beads are prominent. This is a typical example of
a jade disc from the late Liang-chu Culture.
