Harry Winston Diamond Corporation is a specialist diamond enterprise with premium assets in the mining and retail segments of the diamond industry. The Company supplies rough diamonds to the global market. The Company’s retail division, Harry Winston Inc., is a premier diamond jeweler and luxury timepiece retailer with salons in key locations including New York, Paris, London, Beijing, Tokyo and Beverly Hills.

Harry Winston Diamond Corporation’s core business is maximizing the value of its rough diamonds – both the transaction price and by placing tailored parcels of rough diamonds with selected buyers who can, in turn, provide high-quality polished stones for use by our Harry Winston diamond jewelry business.
Harry Winston Diamond Corporation’s primary source of rough diamonds is its 40 per cent ownership of the Diavik Diamond Mine which has some of the richest diamond ore bodies in the world. Through its ownership interest, Harry Winston Diamond Corporation controls approximately 3 per cent of the world’s production of diamonds, by value.
Harry Winston Diamond Corporation achieves added value from its Diavik production by sorting its rough diamonds into sales parcels that meet the specific needs of clients in the diamond capitals of Antwerp, New York, Tel Aviv and Mumbai – functions typically performed by wholesalers and brokers.
Drawing on the full spectrum of Harry Winston Diamond Corporation’s resources, Harry Winston Inc. is embarking on a major growth initiative that will generate industry-leading financial performance from an expanded international network of salons and a broadened range of watches and jewelry that continues to reflect the essence of luxury synonymous with the name.  

Harry Winston Diamond Corporation's principal asset is its 40% interest in the Diavik Diamond Mine, located in Canada's Northwest Territories. Diavik is Canada's second diamond mine, and began producing diamonds in January 2003.
The Diavik Mine is a joint venture between Harry Winston Diamond Corporation and Diavik Diamond Mines Inc. ("DDMI"), a wholly owned subsidiary of London-based Rio Tinto plc. Under Harry Winston Diamond Corporation's joint venture agreement with DDMI, Harry Winston Diamond Corporation pays 40% of the operating and capital costs and has the right to receive and market 40% of the diamond production.  Harry Winston Diamond Corporation does not operate the mine.
The Diavik Mine is based on four diamond-bearing kimberlite pipes located within Lac de Gras. A key milestone in the project was the successful completion of a dike encircling the A-154 South and A-154 North orebodies, and its de-watering during August and September 2002. Harry Winston Diamond Corporation received its initial delivery of rough diamonds in January 2003 and held its first sale of rough diamonds in March of that year. The 42,619 carats of diamonds from A-154 South were sold for a total of US $4,100,692, an average price of US $96.22 per carat for the run-of-mine parcel.
