《周禮·春官·大宗伯》說，「以玉作六器，以禮天地四方，以蒼璧禮天，以黃琮禮地……」這句話表示玉琮是祭祀天地的禮器。玉琮外方內圓，是天圓地方的象徵。玉琮體中心上下穿透的圓孔，可能被視為通天地之通道。所以，玉琮與天地陰陽有關，因此古人對其崇拜至極。玉琮是良渚文化中最具特徵的玉器，不僅是形體最大的器件，也是出土較多的玉器品種。

良渚文化玉琮, H.11.8cm, E.D.19cm,  11kgs。本器大於中國浙江省1986出土餘杭縣長命鄉雉山村反山墓地出土浙江省文物考古研究所藏之琮王(H. 8.8cm, ED 17.6cm,  6.5kgs), 四個角落各有兩組神獸紋, 而各面中間則為兩幅神人騎獸紋. 各細線係由細斜線所組成. 神獸紋為淺浮雕. 本器差異風化及次生長結晶等古玉跡像明顯。
