Arctic Canadian Diamond Company (formerly known as Dominion Diamond Mines, Dominion Diamond Corporation, Harry Winston, and Aber) is a Canadian specialist diamond mining company. Aside from its corporate office in Calgary, Arctic Canadian also has cleaning and sorting facilities in Yellowknife and Mumbai and a marketing office in Antwerp, Belgium. The company once held a 40% stake in the Diavik Diamond Mine Project. Production at the Diavik Diamond Mine, Canada's second diamond mine, is operated by Dominion Diamond Mines' joint venture partner, Diavik Diamond Mine, a subsidiary of Rio Tinto. The mine began producing diamonds in November 2002. In 2012, the company purchased all of BHP's diamond assets; the primary asset is the Ekati Diamond Mine, which is adjacent to the Diavik Mine. Diavik and Ekati combined are estimated to produce over 7 million carats of diamonds in 2014, worth an estimated $1.1 billion.

In July 2017, Dominion announced that it would accept the deal, which closed in November. In June 2017, a deal was signed with online diamond retailer James Allen to make it the exclusive online retailer of CanadaMark diamonds. In October, 2018 a 552-carat yellow diamond was discovered at the Diavik Diamond Mine in Canada's Northwest Territories. By June 2020, the company was close to collapse because sales had stalled so severely during the COVID-19 pandemic. Debt had increased to US$1.2 billion. Since the company would be unable to pay that debt, it was in the process of restructuring through the courts to avoid bankruptcy. In February 2021, Dominion
