Catalogue entry no. 491 by Max Loehr:
491 Ornate Openwork Segment
This delicate piece, carved of whitish, almost transparent jade, involves a design separated into two concentric zones. The outer zone is an animal-headed segment with curls in low relief, while the inner zone shows an openwork symplegma of a feline with turned head and sinuous body, flanked by snakes. The arc spans only 75 degrees. In the outer zone are two perforations, one in the middle and one off center. At one end the jade is encrusted with bronze oxide. Late Eastern Chou.
