298 Ring Segment with Dragon Design
Fragment of a thin-walled ring or bracelet of variegated gray-green jade. Identically engraved on both sides are figures of dragons; behind their convolute tails the space is partly filled with hooked triangles. Only the head of the dragons are carved out, the rest being executed in low relief lines. There is a perforation at the mouth. Early Western Chou.
