The short height and short collars, as well as the type of jade of this cong indicate it being from northwest China. For a similar example that also shows the same kind of alteration and fissures in the stone, see The Complete Collection of Jades Unearthed in China - 15 - Gansu, Qinghai, Ningxia, Xinjiang, Beijing, 2005, p. 32, which was excavated from Qingxicun, Dingxi, Gansu province.
