這玉璧的原料是石質很重的雜玉．經過長時期的渗透變質而成了半雞骨白狀．它看似鬆疏卻仍十分堅硬．两邊三分二的方向各彫有一個似人面的頭紋．跟現存的其他類似嘼面纹有點不同．因工具原始而刀法粗糙，然而頗為細心，能大量减地，也一定花去不少心思．

This is a disc carving with animal masks. After a long period of time being underground it has been fossilized to a greyish white texture. Although it looks rugged, it is still very hard. At two ends along the edge, there were two animal faces being carved, resembling the dragon with long mane behind the large forehead. The workmanship appears to be rough, possible by using primitive tools. Yet the work was conducted carefully. Just to work on the reduction of a large portion of jade to bring up the relief, it would have taken a fair bit of efforts.
