Discover Gahcho Kué Diamonds: Rare Canadian Heirlooms

Far north, where the tundra meets the Arctic Circle and the aurora borealis sweeps across the night sky, lies Gahcho Kué - one of Canada’s most extraordinary diamond mines. Owned by De Beers Canada Inc. and Mountain Province Diamonds Inc., this modern mine has, since 2016, produced some of the rarest and most coveted diamonds in the world.

Diamonds Forged in Ancient Rock

Beneath the frozen expanse of the Northwest Territories, diamonds are unearthed from kimberlite pipes embedded in the Canadian Shield, billion-year-old rock formations among the oldest on Earth. Each winter, the legendary “ice road” opens, carrying supplies across the tundra to this remote landscape, where the Earth’s deepest treasures are revealed.

Provenance with Meaning

The name Gahcho Kué means “place where you find large rabbits or hares” in the Chipewyan language, grounding these diamonds in a story of land and culture. Through the Ní Hadi Xa agreement with six Indigenous Nations, mine operations are guided by stewardship: ensuring the land and wildlife continue to support those who depend on it.

For collectors and connoisseurs, this provenance is as vital as the diamond itself - each gem carrying not only geological history, but a story of respect and responsibility.

Rarity that Glows

Fluorescence is a defining feature of Gahcho Kué diamonds. When exposed to UV light, some reveal a delicate blue luminescence, reminiscent of the northern lights over Canada’s Arctic skies, a subtle marker of their northern heritage.

Even more exceptional, Gahcho Kué yields a select number of Type IIa diamonds. Representing only 1–2% of diamonds mined globally, these stones are free from measurable nitrogen or boron, often perfectly colourless, and prized for their purity. These are the diamonds of kings and collectors - luminous, rare, and timeless.
