From Northwest China
Neolithic or Shang dynasty (2000-1000 BC)
A ritual sceptre of black jade
China had a large stone industry in Neolithic times. As early as 4500 BC, people on China's east coast employed fine polished stone axes and knives. The working of jade was an extension of this. Jade was used for beautifully coloured and prestigious versions of everyday tools. Jade is scarce and very labour-intensive, and so these objects were fashioned for ceremonial, not utilitarian, purposes.
