Since 1975, the Goslarer Kaiserring award has been given, by the city of Goslar, to a distinguished international artist of modern and contemporary art. The award is for artists whose work has given the contemporary art significant impetus. The prize consists of an aquamarine set in gold, in which the seal of Henry IV, Holy Roman Emperor (1050–1106) is engraved. It is made every year by the goldsmith Hadfried Rinke from Worpswede.
