Liangzhu culture
The Liangzhu culture was the last Neolithic Jade culture in the Yangtze River Delta and was spaced over a period of about 1,300 years. The Jade from this culture is characterized by finely worked, large ritual jades such as Cong cylinders, Bi discs, Yue axes and also pendants and decorations in the form of chiseled open-work plaques, plates and representations of small birds, turtles and fish. The Liangzhu Jade has a white, milky bone-like aspect due to its Tremolite rock origin and influence of water-based fluids at the burial sites.
