Abstract: A large number of turquoise objects were unearthed from both the sites of Sanxingdui and Jinsha, and they can be divided into two categories by the presence/absence of inlays. At both sites, turquoise objects were largely excavated from ritual or ceremonial remains related to high-ranking elites. The turquoise objects unearthed from Sanxingdui are dated to the late Erlitou to the mid-late Shang period, while those from Jinsha mainly to the mid-late Shang, suggesting that these turquoise objects overlapped in time. The inlaid turquoise objects from both sites—mainly plaques and animal-shaped ornaments rather than vessels—feature finely polished turquoise pieces embedded onto bronzes or lacquers, a technique closely resembling the craftsmanship from the Erlitou to the Middle Shang periods, particularly comparable to those from the Erlitou and Panlongcheng sites. In addition, turquoise bead ornaments found in the Chengdu Plain may have been influenced by the cultures of the western Sichuan Plateau and even the Gansu–Qinghai region.
