JADE BI WITH EARLY RUSH PATTERN WARRING STATES 475 - 221 BC Diameter: 11 1/4 inches ( 28.3 cm )
This large jade Bi is carved in thin grey-green jade. Jade disks of this sort were carved over several thousand years. Early examples were completely plain. Later versions had an overall pattern of sprouting grain or comma shapes. This Bi is covered in relief on both sides with small elevated and pointed hexagons. It is commonly called the Rush or Matting pattern. This pattern is thought to represent an intermediate stage between plain type and the grain figures.
