What Will Become of the Final Diavik Diamond?

 

Earlier this month, the Diavik Diamond Mine officially ceased operations, drawing to a close a remarkable 23-year chapter in Canada’s diamond history. Over its lifespan, the mine produced approximately 150 million carats, earning a reputation for consistent output and high-quality stones. Now, attention turns to a symbolic question: what will become of the final diamond recovered from this iconic deposit?

As processing of the last ore continues, the ultimate stone has yet to be identified. According to Matt Breen, it may take several weeks to fully clear the system and assess the final production. Diavik was particularly known for its 3 to 4 carat octahedral diamonds, and there is cautious optimism that the last parcel may still yield notable stones.

Any exceptional diamonds recovered during this final phase are likely to be preserved due to their historical significance. Potential outcomes include placement in a regional museum or retention by Rio Tinto as part of its corporate heritage collection.

A Mine at the End of Its Natural Life

While broader softness in the diamond market has led some to speculate on the timing of the closure, Breen emphasised that Diavik has simply reached the end of its economic life. Operating in Canada’s remote north presents unique challenges, including extreme weather, seasonal access via ice roads, and substantial energy requirements. Maintaining profitability required sustained production levels of 300,000 to 350,000 carats per month thresholds no longer achievable at the site.

Despite this, the closure does not necessarily signal the end of diamond development in the region. Infrastructure remains the key constraint. Future viability will depend heavily on reduced logistical costs, particularly through potential government-backed initiatives such as the Arctic Economic & Security Corridor, which could unlock access to known but undeveloped deposits.

The Human Legacy of Diavik

Beyond production figures, Diavik’s legacy is fundamentally a human story. From its discovery by Eira Thomas and her father Grenville Thomas, to the thousands of workers who operated under some of the harshest conditions in the mining world, the project stands as a testament to resilience and ingenuity.

Breen reflected on the unique culture forged at the mine, where extreme conditions were part of daily life. In one instance, during a rescue operation in temperatures nearing minus 30 degrees Celsius, a worker remarked: “For you, it’s cold, dark, and windy. For us, it’s Thursday.” The comment encapsulates the spirit that defined Diavik’s workforce.

Importantly, the mine also leaves behind a strong economic and social contribution to Northern communities. Of the approximately CAD 11 billion spent over its lifetime, CAD 8 billion was directed to Northern businesses, with around half benefiting Indigenous enterprises.

Closure and Beyond

The formal closure process for Diavik is expected to take approximately four years, involving site rehabilitation and environmental management. As the final diamond emerges from the last ore processed, it will serve not only as a geological artefact but as a symbol of one of Canada’s most significant modern mining achievements.

In the end, the true legacy of Diavik may not rest in a single stone, but in the enduring impact it has had on the industry, the region, and the people who brought it to life.

Diavik and First Nation sign closure agreement as diamond mine winds down

 

The Tłı̨chǫ government and Diavik diamond mine have signed a formal closure agreement as the Northwest Territories operation prepares to end commercial production in March.

The agreement was signed on February 26 at a public ceremony at the Cultural Centre in Behchokǫ̀, attended by Tłı̨chǫ citizens, Elders, community members and staff. The event included opening and closing prayers, a community feast and a drum dance.

Diavik and the Tłı̨chǫ government first entered into a partnership agreement in 2000, recognising the importance of Tłı̨chǫ participation across all stages of the project. Over the life of the mine, that partnership has included commitments to employment, training, contracting and community investment.

Tłı̨chǫ citizens gained work experience and developed trades and technical skills during construction and operations, while Tłı̨chǫ businesses expanded capacity through contracting opportunities. Elders and community members also contributed Traditional Knowledge and feedback during construction, operations, closure planning and remediation activities.

With Diavik transitioning into closure following more than two decades of production, the new agreement outlines commitments to safe and responsible reclamation and long-term stewardship of Tłı̨chǫ lands. It includes funding for socioeconomic mitigation measures to support Tłı̨chǫ-led initiatives during the closure phase, as well as continued commitments to employment, training and business opportunities.

“Our partnership with the Tłı̨chǫ government has been foundational to Diavik’s success,” said Diavik COO Matthew Breen.

“We are proud to continue to strengthen those bonds as we move into closure, working together towards a positive future for Tłı̨chǫ members and communities. We will continue to treat the people, the land and waters with respect, to allow for traditional and cultural activities on the reclaimed land, and to leave a lasting and positive legacy in the NWT.”

Rare purple diamond unearthed at Diavik

Vibrant 0.45-carat gem adds final flourish to Diavik’s closing years.
Just when it seemed Diavik had given all it could give, a rare purple diamond has been unearthed at the Northern Canadian mine – a 0.45-carat stone that stands out in a region better known for producing predominantly colorless gems and the occasional yellow stone, adding a splash of unexpected color as the operation approaches the final years of its mine life.

The discovery, quietly announced by Rio Tinto via social media, comes just weeks after the recovery of a 158.2-carat yellow diamond and a 50-million-year-old petrified log – both of which drew attention to the remarkable geological and historical treasures still surfacing from the remote subarctic site.

“We recently had a unique discovery at Diavik – a rare purple diamond weighing in at 0.45 carats,” the company wrote in a social media post on LinkedIn.

“Diavik diamonds are typically white, so this came as a pleasant surprise,” the post continued. “The purple colour likely comes from a trace element such as hydrogen or a twist in the crystal lattice structure of the diamond. The shape of the rough diamond is known as a ‘makeable’ which means it will likely be cut into a single diamond.”

Though small in size, the stone is striking for its rarity, with colored diamonds of any kind making up less than 1% of Diavik’s total production over more than two decades of operation.

Among them, purple diamonds are the rarest, their distinctive hue typically attributed to hydrogen impurities or plastic deformation deep in the Earth’s mantle – a result of the intense pressure and heat that alters the crystal structure during formation.

In gemological terms, purple diamonds are often classified under the broader category of “fancy color” stones, though few attain the deep saturation necessary for that label. More often, their shades fall within the purplish-pink or violet spectrum, with pure purple standing as one of the most elusive colors in the diamond world.

For Diavik, the recovery of such a specimen near the end of its mine life serves as both a scientific curiosity and a symbolic capstone.

Since beginning production in 2003, the mine has yielded over 140 million carats of rough diamonds – predominantly colorless, with a handful of exceptional yellow stones including the 552-carat “egg” discovered in 2018 and the more recent 158.2-carat find earlier this year.

Yet, while the occasional yellow diamond has offered moments of brilliance, the purple discovery stands out for its singularity.

While not the first purple diamond recovered from Diavik – industry veterans have noted smaller specimens dating back more than a decade – this 0.45-carat stone ranks among the most notable, particularly for its size, clarity, and timing near the end of the mine’s operational life.

Purple diamonds are so rare that only a few notable examples have surfaced globally, often fetching premium prices far beyond their white or even pink counterparts. Their appearance in the trade is sporadic, and their origin even more geographically restricted – making a Canadian purple diamond an especially uncommon occurrence.

Diavik’s purple gem is expected to be cut into a single polished stone, though no details have been released about where it might end up – in private hands, a high-profile auction, or perhaps a Canadian institution.

Whatever its path, the find adds a final chapter to Diavik’s legacy – a small but vibrant reminder that even in its twilight, the remote Arctic mine remains full of surprises.

Canada's Big Three Mines Could Close Early

Canada’s three biggest diamond mines could be forced to close early, an economist has warned, amid the ongoing slump in prices.

Operators reported losses last year for Diavik, Ekati and Gahcho Kue, all in Canada’s Northwest Territories (NWT).

They are slated for closure as they reach the end of their lives – estimated at 2026, 2029 and 2030 respectively – but dwindling demand may render them uneconomic before those dates.

Graeme Clinton, an economist in Yellowknife, capital of NWT, told CBC, Canada’s national broadcaster : “I don’t think nearly enough is made of the state of the markets which are most important to our economy. These low prices could very well mean an early closure.”

He qualified his comments by saying that none of the miners had so far indicated that they’d bring forward their closing dates.

Diamond mining is key to NWT’s economy, representing over a quarter of its GDP, but miners have been hit hard by the downturn.

Rio Tinto’s Diavik mine lost CAD 127m (USD 94.6m) in 2024, Burgundy’s Ekati lost CAD 94.7m (USD 70.5m) and Mountain Province, minority-owner of Gahcho Kue lost CAD 81m (USD 60.0m).

Early closures would cost thousands of jobs, and would dent NWT’s economy.

Diavik recovers 158.20 carat ‘miracle of nature’ diamond

One of the largest gem-quality yellow diamonds ever discovered in Canada, has been unearthed from Rio Tinto’s Diavik Diamond Mine.

The 158.20-carat rough diamond is one of only five yellow diamonds weighing more than 100 carats ever unearthed at Diavik in its 22-year history, stated a release.

Diavik’s production primarily consists of white gem quality diamonds, with less than one percent of its production yielding rare yellow diamonds.

Diavik Diamond Mines Chief Operating Officer Matt Breen stated: “This two-billion-year old natural Canadian diamond is a miracle of nature and testament to the skill and fortitude of all the men and women who work in Diavik’s challenging sub-Arctic environment.”

Patrick Coppens, sales and marketing GM for Rio Tinto’s diamonds business, stated: “The beauty and purity of Diavik diamonds continues to excite passions amongst all who see them and we look forward to following the onward journey of this very special diamond.”

$127m Diamond Loss for Rio Tinto

Rio Tinto reported a $127m loss for 2024 from its Diavik diamond mine, in Canada, as weak market conditions led to “fixed cost inefficiencies”.

That compares with underlying earnings of $26m in 2023. Rio Tinto’s diamond sector generated $297m of revenue during the year, a 37 per cent drop on $444m the previous year.

The British-Australian multinational emailed over 1,300 employees last September, offering them voluntary separations to reduce operating costs as it prepares to close the mine next year.

In its Full Year Results 2024 the company noted the tragic loss of four Diavik workers and two air crew when a plane headed for the mine crashed last January.

Rio Tinto reported a 17 per cent drop in production, from 3.3m carats in 2023 to 3.4m carats in 2024.

The company acquired full ownership of the mine in November 2021 after it bought out a 40 per cent stake from Dominion Diamond Mines.

Rio Tinto offers early termination to Diavik employees to save costs

Rio Tinto is offering early termination for employees at its Diavik diamond mine as part of the company’s efforts to save costs ahead of the mine’s closure in 2026, the Australian miner told jewelry news agency Rapaport.

Located in Canada’s Northwest Territories, about 200 km south of the Arctic Circle, Diavik has become an integral part of the NWT economy, employing over 1,000 people and producing an average of 6-7 million carats of gem-quality diamonds annually.

Sign Up for the Precious Metals Digest

Since entering production in 2003, the mine has outputted roughly 90 million carats of rough diamonds, making it one of the largest in Canada.

The offer of early termination to Diavik employees, says Rio Tinto, is a response to the challenges currently facing the diamond industry as the mine approaches the end of its life cycle.

“I can confirm that Diavik is looking at voluntary separation as part of our efforts to manage costs and rightsize our business given the relatively short runway to Diavik’s planned closure,” Matthew Breen, chief operating officer at Diavik, told Rapaport.

While the diamond mine is slated to close in the first quarter of 2026, Rio previously indicated that some workers will remain at the mine site until 2029 to support the closure and reclamation process.

Elsewhere in NWT, De Beers’ Gahcho Kué mine, about 280 km away from Yellowknife, is expected to follow Diavik and close around 2030.

A report earlier this year shared by research firm Impact Economics estimates that these NWT diamond mine closures could result in 1,500 jobs being lost and about 1,100 residents leaving the territory.

Rio Tinto Workers Killed en Route to Diavik Diamond Mine

A number of remote employees at Rio Tinto’s Diavik diamond mine in Canada died Tuesday after the small plane carrying them to the site crashed.

“We have been informed by authorities that a plane on its way to our Diavik mine, carrying a number of our people, crashed…resulting in fatalities,” said Rio Tinto CEO Jakob Stausholm.

The company has not disclosed how many died on board the aircraft, which seats 19 people. The plane crashed near Fort Smith in the Northwest Territories shortly after takeoff. Rio Tinto employs many remote workers, who operate in shifts at the mine. Because of its isolated location, the miner transports workers by aircraft to and from the deposit.

“I would like to extend our deepest sympathy to the families, friends and loved ones of those who have been affected by this tragedy,” Stausholm said. “As a company, we are absolutely devastated by this news and [are] offering our full support to our people and the community, who are grieving today. We are working closely with authorities and will help in any way we can with their efforts to find out exactly what happened.”

Northwest Territories Premier R.J. Simpson also mourned the loss.

“It is with a heavy heart that I express my deepest condolences to the families, friends, and loved ones of those who were aboard the Northwestern Air flight that crashed outside of Fort Smith today,” he noted. “The impact of this incident is felt across the territory…. As we seek to understand the circumstances of this tragedy, I’d also like to extend a heartfelt thank you to the first responders and rescue teams who continue to work tirelessly at the crash site.”

It is unclear whether the crash will impact diamond production or sales at Diavik.

Rio Tinto to spend $40m on Diavik diamond mine expansion

 Rio Tinto to spend $40m on Diavik diamond mine expansion

Rio Tinto is going ahead with a $40 million expansion of its iconic Diavik diamond mine in the Northwest Territories of Canada, which will extend the operation’s life to at least early 2026.

The approved first phase of the project will expand diamond extraction underground, below the existing A21 open pit. Mining of that area, opened in 2018, recently concluded.

A second phase an additional cost will be put forward for approval in 2024, Rio said.

Phase one below A21 is slated to produce an extra 1.4 million carats, with phase two adding another 800,000 carats.

“This is good news for our employees, partners, suppliers and local communities in the Northwest Territories,” Sinead Kaufman, Rio Tinto Minerals’ chief executive, said in a statement.

Rio Tinto became in 2021 the sole owner of the operation, after buying the 40% share held until then by Dominion Diamond Mines.

The company has operated Diavik since production began in 2003. Located approximately 300 km north-east of Yellowknife, the mine employs over 1,100, of which 17% are Northern Indigenous people.

Diavik is Canada’s largest diamond mine in terms of production with between 6 and 7 million carats of rough diamonds produced each year. Since mining began in 2003 Diavik has produced over 100 million carats of diamonds.

The Northwest Territories’ two other diamond mines – Ekati, operated by Arctic Canadian Diamond and De Beers-Mountain Province’s Gahcho Kué – are expected to close in 2024 and 2028, respectively.

Diavik is about 30 km southeast of Ekati, and Gahcho Kué is 125 km southeast of Diavik.

Rio Tinto Production to Slump as Diavik Dries Up

                     The Diavik diamond mine

Rio Tinto has forecast a sharp drop in rough-diamond output for next year as the Diavik mine edges closer to depletion.

The company expects to produce between 3 million and 3.8 million carats from the Canadian deposit in 2023, it reported at an investor seminar Wednesday. That compares with a plan of 4.5 million to 5 million carats for this year.

The decrease is a result of the exhaustion of rough supply from some of Diavik’s major mining areas, a Rio Tinto spokesperson told Rapaport News. The mine, which employs 1,100 workers, is set to close in 2025.

“We’ve completed mining at the A21 pipe, which was the latest pipe opened in 2018,” the spokesperson explained. “We’re finishing surface mining, and also one of the underground parts of the mine is done, so this is part of the plan changes. There are four areas we are mining at the moment, and next year there will be two.”

Diavik, of which Rio Tinto is the sole owner, is currently the miner’s only operational diamond site. The company’s Argyle deposit, known for its fancy-pink diamonds, closed in November 2020. Meanwhile, an exploration partnership with Star Diamond is on hold as Rio Tinto considers an exit from the project.

Rio Tinto Buys Remaining Share of Diavik Diamond Mine

                            

Rio Tinto, the world’s second-largest miner, just became the sole owner of the Diavik diamond mine in Canada’s Northwest Territories on Thursday. Despite saying in the past the Company was not interested in taking full control of the aging arctic mine, Rio Tinto ended up buying the 40% share held by Dominion Diamond Mines for a total stake of 100%.

Part of the transaction includes Rio Tinto releasing Dominion and its lenders from any outstanding liabilities or obligations involving funding the operation or the closure of the joint venture. On the other end, Rio Tinto will receive all remaining Diavik assets held by Dominion including a security cash collateral for the potential future closure for the mine and unsold production.

Why the Buyout Now?
Dominion, which used to be the fourth-largest diamond producer, suffered some financial troubles which played out in court over several months last year. These troubles ultimately led Dominion to sell its other Canadian mine, Ekati in December 2020. In 2017, The Washington Companies ended up buying the Company for $1.2 billion.

This deal follows a 19 month long process beginning in April 2020 by Dominion Diamond Mines filing for insolvency protection under the Canadian Companies’ Creditors Arrangement Act.

Diavik has been in production since 2003 and is eventually facing closures in 2025 which will cost hundreds of millions of dollars to fully clean up. Diavik is Canada’s largest diamond mine, and yielded 6.2 million carats of rough diamonds in 2020.

Rio Tinto Minerals boss Sinead Kaufman said in a statement, “Diavik will now move forward with certainty to continue supplying customers with high quality, responsibly sourced Canadian diamonds.”

Worries and concerns began to surround the diamond market due to production coming to a

halt during the global COVID-19 pandemic, with some people worried the market would never recover. However, Alrosa, the world’s top diamond miner by output, claims the market has fully recovered from the effects of the global pandemic, and sales of jewelry and rough diamonds are up 23% this year compared to 2020.

Rio Tinto asks court to OK sale of partner's diamonds in Canada mine

 

Global miner Rio Tinto is seeking court approval to sell its partner’s share of diamonds from a mine in Canada’s Northwest Territories, a filing showed, hoping to recover around C$120-million plus legal fees and other costs.

Rio owns 60% of Diavik Diamond Mines Inc (DDMI) and says it is owed C$119.5-million plus about C$2.4-million in fees by junior partner Dominion Diamond.

Dominion holds a 40% stake in the northern mine, located about 300 km north of the territorial capital of Yellowknife.

Closely held Dominion sought creditor protection in April, saying it could not afford Rio’s cash calls amid coronavirus-related disruptions in the global diamond industry.

Dominion said October 9 a proposed deal to sell its nearby Ekati mine to an affiliate of its parent company The Washington Companies for $126-million fell apart. That deal did not include its minority Diavik stake.

DDMI said in court filings that Dominion has not repaid cover payments and “has no intention of doing so” and that it would be “unjust and inequitable” to not permit DDMI to recover the amounts owing to it in accordance with its joint venture agreement.

“We remain focused on ensuring Diavik diamond mine continues to operate safely, maintaining the mine’s significant contribution to the Northwest Territories and local communities through payments to government, employees and suppliers,” a spokesman for Diavik said on Friday.

A court hearing on the application is set for October 30 in Calgary, Alberta.

Diavik produced 6.7-million carats in 2019 but is scheduled to close in 2025, with cleanup costs estimated at $365.3-million, according to court documents.

Dominion declined comment on the fate of its Diavik stake. Rio has said it will not bid on the minority interest.

552 Carat Yellow Diamond Is The Largest Ever Found In Canada

Finding exceptionally large diamonds is rare. Finding extra large diamonds in fancy colors is even more rare. As such, the announcement by  Dominion Diamond Mines that it has unearthed  the largest known diamond ever found in North America is big news.

 Found in October at the Diavik Diamond Mine in  Calgary, Canada, the Canadamark yellow diamond weighs in at 552 carats and beats the previous record (held by the Diavik Foxfire diamond) of 187.7 carats that was also found at the same mine.

Dominion Diamond Mines ULC sources responsibly mined diamonds and owns 40 percent of Diavik.

 The Diavik Diamond Mine is just shy of 150 miles south of the Arctic Circle in the Northwest Territories of Canada, and has produced several important stones in the past. This newest discovery measures about 1-1/2 inches in diameter and more than 2 inches in height. The color and texture are unique geologically speaking, as such a large and rare yellow diamond doesn’t usually form in the region. According to Dominion Diamond Mines’ release, “Abrasion markings on the stone’s surface attest to the difficult journey it underwent during recovery, and the fact that it remains intact is remarkable.”

The Canadamark(TM) program by Dominion Diamond Mines ensures that all diamonds bearing its logo are rigorously tracked from mine to polished gem in order to offer final consumers  full transparency of the supply chain. Once the rough is cut, the diamonds will  be certified as Canadamark(TM).

In the case of the previously found Diavik Foxfire diamonds,  rather than sell it in the rough, the stone was  cut and polished  — yielding a 37.87-carat brilliant-cut pear shaped diamond and a 36.80 carat brilliant-cut pear shape. Both of these stones sold recently at a Christie’s auction for $1.3 million.  It is expected that Dominion Diamond Mines will take the same approach with the 552-carat Canadamark(TM) yellow diamond. The yield could be several larger sized diamonds that Foxfire, or could be similar sizes but more of them.  It is impossible to know, as a rough diamond must be carefully studied before being cut to determine the perfect size and shape of the finished, polished stones that will show off their most beautiful color and brilliance.

Certain other fancy yellow  diamonds have made history. In fact, among the world’s largest yellow diamonds is the 439.86 carat light-yellow diamond that was found by DeBeers in 1888 and later cut into a 234.65-carat cushion-cut stone.  The Tiffany Yellow Diamond is also one of  the largest ever discovered. It weighted 287.42 carats in the rough when it was found in 1878 in the Kimberly Mine in South Africa. It was eventually cut in to the 128.54-carat cushion known a the Tiffany Yellow Diamond.

According to  a release issued by Dominion Diamond Mines, Kyle Washington, Chairman, says  “This incredible discovery showcases what is truly spectacular about Canadamark diamonds. “The color and texture of the diamond are a unique example of the journey that natural diamonds take from their formation until we unearth them. Our Diavik Mine has produced some of the most beautiful diamonds in the world, and this one certainly tops the list.”
