A JADE DISC, HUAN, EASTERN ZHOU DYNASTY China, 8^th-3^rd century BC. The disc is neatly decorated in low relief with archaic motifs of s-scrolls, interspersed by four evenly spaced mythical beasts with dragon heads and fish bodies, showing neatly incised scales and tail fins, all between slightly raised borders. The translucent stone is of a pale celadon to russet and dark brown tone with areas of semi-opaque calcification.

Since the late 1980s, they have been collecting ancient Chinese jades, building an extensive and multiply published collection over the decades.
Condition: Very good condition with some old wear and minuscule nibbling here and there. The stone with natural inclusions and fissures, some of which may have developed into small hairline cracks over time. Signs of natural weathering and erosion, surface alterations.
