Cowell: How Did Black Jade Become Part of a Farming and Fishing Town?

Cowell sits on the eastern side of South Australia's Eyre Peninsula, on Barngarla Country, facing the sheltered waters of Franklin Harbour. European pastoral settlement began in the district in 1853, and the township named in 1880 later used its harbour to move wool and grain. It remains a service centre for surrounding farms and for fishing and aquaculture in the harbour and gulf.

A different kind of recognition came from nephrite in the rocks outside town. In 1965, local farmer Harry Schiller picked up an unusually tough stone near an outcrop of white dolomitic marble. The University of Adelaide and the South Australian Museum subsequently identified it as nephrite. South Australian geological records say that more than a hundred outcrops are now known across the roughly ten-square-kilometre Cowell Jade Province. The material ranges from yellow-green and green to black; fine-grained black nephrite can take a mirror polish.

Jade did not turn Cowell into a single-industry mining town. Instead, it added a portable, workable and memorable identity to an older structure built on farming, the harbour and fishing. What distinguishes Cowell is not only the size of the deposit, but the way a material buried in local geology entered the community's account of itself through discovery, cutting and display.
