Large double-headed dragon huang of the period were included in a set of jade ornaments which during the Warring States period was typically worn hanging down a belt. These double-headed huang were usually hung at the bottom of the assembled set, with the concave portion facing downward, presumably to assist in maintaining an overall structural balance to the set. |Compare a related jade huang with similar spiral bosses in low relief, in the Palace Museum, Beijing, illustrated in Compendium of Collections in the Palace Museum: Jade 3, Beijing, 2011, p.69, no.66; and another related larger pale green jade huang, late Warring States period, with pointed snouts, in the National Palace Museum, Taipei, illustrated in Art in Quest of Heaven and Truth – Chinese Jades Through the Ages, Taipei, 2012, p.101, no.5-6-17.|此璜青灰色玉質，幾乎白化。扁平狀，弧形，近似半圓型，兩端雕對稱龍首，龍首有角，眼睛呈圓形，翹鼻，口微張，下吻向嘴內彎卷，器身飾淺浮雕密集榖紋，反面飾相同紋飾，璜頂中央有一小圓孔，可供穿繩繫掛。此璜造型對稱工整，雕琢精細。|相關例子可參考北京故宮博物院藏一1977年安徽省長豐縣楊公鄉戰國墓出土的玉龍首璜，其淺浮雕紋飾與本器可資比較，見《故宮博物院藏品大系:玉器編3:春秋戰國》，北京，2001年，頁69，編號66。另參看一件台北國立故宮博物院藏一件戰國晚期的龍紋珩，著錄於《敬天格物：中國歷代玉器》，台北，2012年，頁101，編號5-6-17。
