The Neolithic jade of Canada

Before the arrival of Europeans, jade was mainly shaped for tools by certain groups, including the Salish in southern British Columbia. Workshops of cutting have been discovered in the region of Lillooet along the Fraser River where we could find jade in form of pebbles. We estimate that  jade carving has spread over a period of at least 3,000 years.

Many objects shaped in these workshops were found in Alberta, Washington State and elsewhere because they were popular for trading.

Note that the working technique is the same as the one used by the Maori of New Zealand: an abrasive stone used as a saw to cut or as a point to drill.
