A calcified jade bead necklace, Neolithic period, Liangzhu culture or middle Yangzi region, 4th - 3rd millennium BC | 新石器時代 良渚或長江中游文化 公元前四千至三千年 玉管項飾

It is worth noting although most of the Liangzhu jade bead necklace are undecorated, one carved bead stands out among the present string of undecorated beads. See a related jade bead necklace, Liangzhu culture, excavated from No. 1 Tomb of Sidun, Wujin county, Jiangsu province, now in the Nanjing Museum, illustrated in Yang Boda, Zhongguo yuqi quanji [Complete collection of Chinese jades], Hebei, 2005, no. 216.

此串玉管項飾，其中一玉管刻有人面紋，相對大部分出土的素面玉管串飾較為少見。參看1978年江蘇省武進縣寺墩1號墓出土良渚文化玉串飾，現藏於南京博物院，見楊柏達，《中國玉器全集》，河北，2005年，圖216。
