Catalogue entry no. 391 by Max Loehr:
391 Large Disk with Pattern of Plastic Cones
Essentially similar to the types listed from No. 385 onward, except that the curls are not rounded nubs but pointed cones. The jade is bone-colored; only a few spots of greenish hue reveal its original color. Its surface, to which patches of cinnabar still adhere, retains a remarkable gloss. The perforation seems to be almost cylindrical. Late Eastern Chou.
