The four C’s of a conventional diamond are color, clarity, cut and carat weight. Deepak Kumar is fond of saying that his stones will have six C’s. “The fifth C is for ‘conflict-free,’ and the sixth C is for ‘Canadian,”’ Mr. Kumar said in a telephone interview from Yellowknife — population 20,000 — the capital of Canada’s Northwest Territories.
Mr. Kumar’s company, Deepak International, announced this summer that it had bought two defunct diamond polishing plants in Yellowknife for 1.9 million Canadian dollars, or $1.7 million, together with the exclusive rights to the polar bear symbol, a quality logo for the Territories’ sustainably mined stones.
As consumers increasingly ask where their diamonds are sourced, polished and cut, Canadian diamonds have a reputational advantage. They are marketed as conflict-free and cleanly mined under the Canadian Diamond Code of Conduct, overseen by the federal government, that goes beyond the Kimberley Process certification program, established in 2003, which sets minimum standards for ethical diamond mining.
“Canada is a wonderful story. It is icy, it is clean, it is cold,” said Dylan Dix, an executive with HRA Group, Canada’s biggest diamond producer.
Industrial-scale diamond mining started in Canada in the 1990s — just as stories of war atrocities and exploitation began to roil the market for African gemstones. Canada has since become the world’s third-biggest diamond producer, after Botswana and Russia.
