Catalogue entry no. 92 by Max Loehr:
92 Disk in Three Segments
Translucent, light greenish gray stone with light brown markings and creamy white calcified streaks. The three segments are of unequal size, their arcs measuring about 130, 102, and 128 degrees. A slightly curved ledge on the underside of one segment (c) suggests the use of a very large swinging saw; an apparently straight ledge—intersected by the perforation—remains on another segment (a). Near the adjoining edges of the three segments, small conical holes have been drilled, which would permit the pieces to be held together by thongs or wires. Shang or Western Chou(?).
