The collapse of natural diamond prices has pushed the operator of Canada's oldest diamond mine into insolvency, ending a 28-year era of Arctic prosperity.
When Arctic Canadian Diamond Company filed for protection under Canada's Companies' Creditors Arrangement Act on May 2, 2026, it was not simply a corporate restructuring event. It was the most visible sign yet that the global diamond industry faces a structural reckoning from which it may not emerge unchanged. The operator of the Ekati Diamond Mine in Canada's Northwest Territories, a subsidiary of Perth-based Burgundy Diamond Mines, arrived at the BC Supreme Court's door carrying roughly $343 million in liabilities and a workforce that had shrunk from 1,242 employees in 2024 to around 340 by March 2026. Behind those numbers lies a story about technology, tariffs, Chinese consumer preferences, and the moment when a synthetic stone became indistinguishable from the real thing.
The immediate trigger for the CCAA filing was a price collapse of historic speed. According to Brent Mierau, corporate secretary and head of finance for Arctic Canadian, the average price per carat for an Ekati diamond stood at $92 at the end of 2024. By December 2025, that figure had dropped to $24 per carat, with the mine's last two rough diamond sales averaging just $27. A 74 percent price decline in under 12 months had made extraction commercially unviable. Revenue across the Ekati operation fell from more than $600 million in diamond sales in 2024 to roughly $253 million the following year. Burgundy recorded a net loss of US$86.8 million in 2025 alone. The Burgundy Group as a whole carries total liabilities of approximately $655 million.
Mierau's affidavit cited three converging forces: the explosion of lab-grown diamond alternatives, a sharp withdrawal of Chinese consumers from the natural diamond market, and US tariffs on Indian imports that severed a critical link in the global polishing chain. Most rough diamonds are cut and finished in India before sale into American retail. When Washington imposed heavy tariffs on Indian exports, the pipeline seized. "United States tariffs on jewelry imports have caused lower demand and lower diamond prices," Mierau wrote, noting that even a partial rollback in 2026 had not reversed the damage. "The tariffs imposed by the United States and other global forces have had a sudden and blunting impact on the diamond market, with direct negative implications for upstream producers such as Arctic Canadian."
The lab-grown diamond's rise from novelty to market disruptor happened faster than almost any analyst predicted. Lab-grown diamonds, which were roughly 30 percent cheaper than natural stones in 2015, had become 80 to 85 percent cheaper by 2025, with one-carat lab-grown stones retailing for $800 to $2,000 against $4,000 to $9,000 for mined equivalents. Their share of US engagement ring purchases climbed from 5.2 percent in 2019 to 45 percent by 2024. The ethical selling point that once distinguished Canadian mined diamonds from conflict stones has weakened; synthetic producers can make similar claims about traceability and social responsibility.
The damage has been industry-wide. De Beers, the world's dominant diamond miner, built up approximately $2 billion in unsold natural stones through 2025, cut more than 1,000 jobs, and took a $2.3 billion pre-tax impairment on its balance sheet through its parent Anglo American. Russia's Alrosa saw profits fall nearly 80 percent. Under the so-called Luanda Accord, major producing nations including Botswana and Angola pledged to dedicate 1 percent of annual diamond revenues to a collective marketing campaign for natural stones. None of these measures arrested the price slide before Ekati ran out of runway.
Ekati opened in 1998, the first surface and underground diamond mine in Canada, after geologists Chuck Fipke and Stewart Blusson discovered 81 small diamonds at Lac de Gras in the Northwest Territories in 1991, triggering the largest diamond staking rush in North American history. The find placed Canada alongside Russia and Botswana as a top-tier producing nation. At peak employment, Ekati and its NWT neighbors Diavik and Gahcho Kue together employed more than 4,000 workers, with over 3,000 being Indigenous. For communities hundreds of kilometres northeast of Yellowknife, accessible only by air or seasonal winter roads, the mines anchored an economy and a way of life.
Burgundy Diamond Mines acquired Arctic Canadian in 2023, becoming the fourth operator of Ekati and the second to file for insolvency protection while running the mine. The first insolvency came during the early pandemic in 2020 under the then-operator Dominion Diamond Corp. Burgundy acquired the mine from a consortium of wealth management firms that had originally rescued it from that earlier crisis. By July 2025, Burgundy had already halted open-pit operations at the Point Lake section of the mine, resulting in hundreds of additional layoffs. At the time of the CCAA filing, Ekati had received C$115 million from the Canada Enterprise Emergency Funding Corporation, with a further C$60 million contingent on the company raising C$25 million in new equity by the filing date. The court has since extended protection to July 28 and approved an additional C$60 million in interim financing while the company pursues a formal sale process, with bids due September 25, 2026.
The creditor protection filing put more than jobs at risk. Under the impact benefit agreements Arctic Canadian holds with surrounding Indigenous governments, the company owes those communities millions of dollars in annual payments. At the end of 2025, the mine was in arrears by approximately C$5 million for 2025 payments and a further C$3.2 million for 2026. Total outstanding IBA obligations across all agreements stood at roughly C$45 million. The reclamation liability compounds the picture further. Burgundy estimates full site remediation at Ekati will eventually cost C$428 million, but the security instruments currently held by the company appear to fall roughly C$100 million short of that figure, raising concerns that governments could be left with a significant cleanup burden.
NWT Industry Minister Caitlin Cleveland issued a measured statement after the filing, saying her government was monitoring court proceedings and advocating for northern workers and communities. "Our priority right now is people," she said, pointing residents toward income support programs, career counselling, and retraining services. Federal MP Rebecca Alty expressed concern and said the government's main focus was on mine employees.
With Rio Tinto's Diavik mine having ceased production in March 2026 after more than two decades, Ekati and De Beers' Gahcho Kue are the only remaining diamond operations in the NWT. Gahcho Kue is expected to operate until around 2030. If Ekati closes early, the NWT faces the end of a mining era that at its peak contributed roughly a quarter of the territory's GDP and provided economic infrastructure for communities across a population of 45,000 people.
The CCAA process keeps options open. Burgundy has maintained that Ekati contains significant undeveloped resources, including the Jay kimberlite pipe, described by CEO Kim Truter as "one of the largest undeveloped kimberlite pipes on the planet." The company contends the mine could theoretically operate until 2040. Court-appointed monitor FTI Consulting is overseeing the sales and investment solicitation process. Whether a buyer emerges willing to absorb $655 million in group-level liabilities, manage complex Indigenous obligations, and bet on a natural diamond price recovery in an era of lab-grown abundance remains the open question at the heart of Canada's Arctic.
