Diamonds from the Diavik Diamond Mine are extracted from three ore deposits in kimberlite pipes below the arctic Lac de Gras in Canada’s north. The pipes, called A154 South, A154 North, and A418, are small in diameter by global comparison, but have a grade of over three carats per tonne by world average, but are very high grade with some of the world's highest per tonne ore value. Rio Tinto’s 60 per cent share of the Diavik marketable reserves are estimated at 46.2 million carats of rough diamonds (Rio Tinto annual Report 2007)

Diavik diamonds offer the international diamond market a commercially desirable range of good color, gem quality rough diamonds, with most of the value lying in white stones of one carat and larger and of good commercial clarity and shape. Diavik’s diamonds enjoy a high profile in the international diamond market; many of the world’s established diamond polishing centers are interested in receiving a share of Diavik diamonds.

Under the joint venture agreement with Harry Winston Diamond Mines Ltd, each partner retains the right to receive and market its share of all diamonds produced. Diavik Diamond Mines Inc has 60 per cent share of the diamonds which are marketed by its sister company and sales agent, Rio Tinto Diamonds in Antwerp, Belgium. Rio Tinto Diamonds’ clients include Yellowknife diamond cutting and polishing plants.

Harry Winston Diamond Mines Ltd supplies rough diamonds to the global market through its 40 per cent ownership in the Diavik Diamond Mine and owns jeweller Harry Winston Inc.
