Abstract
With increasing demand for high quality diamonds and some classical, producing deposits becoming expensive, worldwide exploration for new diamond deposits continues to grow at an ever increasing speed. Since the beginning of the 1990s new regions like the shield areas of Canada and USA have rapidly came into focus and since the beginning of the 1990s even the Nordic countries like Sweden, Norway and Finland have attracted international diamond exploration companies. One of the main reason is major changes in mineral policy and legislation, which were introduced primarily in Sweden and Finland.
