Identification:
Carved with white jade, the cong has eight sections alternating arrangement of deity faces and crowns which has curvature cut mark that may be interpreted as the recording of the pass away of the queen. Comparing to the typical Liangzhu congs, this one has employed more elements of low relief carvings such as the eyes of the deity.  Antiquity evidence includes dissolved pits, calcification, additive crystals, cleaving vein & deteriorate marking.

良渚文化玉琮, H.30.5cm, W. 6cm, 1800grams。本器玉琮系以白玉雕琢有八节分别相间雕琢神面及后冠, 意味此時良渚文化已從從神權演進到王權. 各节之间有深刻的阴线. 神面及后冠系以浅浮雕为之, 而修饰之线条则为后来战国所流行的游丝线.. 值得注意的是, 在每个后冠上又弧形凹槽, 有可能是记录皇后之逝世重大事件, 本器差异风化, 蚀孔, 冰裂纹及次生长晶体等古玉迹象明显。.
