Catalogue entry no. 333 by Max Loehr:
333 Crenelated Tablet with Bird Décor
Very thin tablet, its outline tapering, cut from a piece of translucent dark green jade with minute dark blue and gold flecks. Except for the base, the contour is carefully, if not quite symmetrically, crenelated and notched. Engraved bird figures, identical on both sides, fill the given spaces. They compare with those on No. 332 if details are disregarded; in this case, however, there are no dragon heads. Late Western Chou.
