The Kongsberg Silver Mine was discovered in 1623. King Christian IV claimed the mine for the Crown and German miners were imported to work it. It was a very rich mine and Kongsberg became Norway’s largest city. By 1771, 80 silver mines were in full production and yielded 1370 tonnes of pure silver. The mines were in production until the late 1950s.
Albert Chapman acquired this specimen through an exchange with the University of Paris in 1976.
