Pink and yellow diamonds from two iconic Rio Tinto mines – Argyle and Diavik – have been brought together to create a unique ring.
It’s called Diavik Midnight Sun and has been valued at $1.24m.
An 18.08 carat fancy intense yellow oval diamond from Diavik, in sub-Arctic Canada, contrasts with an intricate setting of rare Argyle pink diamonds, from the now-closed mine in in the remote East Kimberley region of Western Australia, weighing 4.09 carats in total.
The yellow diamond was cut from a 36.75-ct rough gem, described as one of the finest large yellow diamonds uncovered at Diavik.
Rio Tinto’s general manager of sales and marketing for its diamonds business, Patrick Coppens said “This combination of a rare yellow Diavik diamond and Argyle Pink Diamonds, the rarest diamonds in the world, is a special moment in the history of Rio Tinto’s unique place in the natural fancy coloured diamond industry.
He paid tribute to luxury jeweler Musson for creating the ring. The Diavik Midnight Sun takes its inspiration from the exquisite natural phenomenon that occurs when the sun is seen at midnight in the Arctic, exhibiting beautiful golden and pink hues.
A rivière diamond necklace was the top seller at Christie’s Magnificent Jewels in Hong Kong on Monday, bringing in $5.9 million.
The sale price for the piece, which features 52 round brilliant-cut, D-flawless and internally flawless diamonds weighing a total of 104.84 carats, was within estimates. In total, the November 28 auction achieved $46.2 million, with 50% of the jewels on offer exceeding their high estimates, Christie’s said Monday.
The company sold 86% of available lots, or 82% by value, and drew global participation from 21 countries across three continents.
The auction also included a collection of jewels from Hong Kong actress Rosamund Kwan, which fetched a combined total of $11.1 million. The two leading lots from that sale saw heavily competitive bidding, lasting over 15 minutes, Christie’s noted. The top item in the group was a necklace featuring a pear brilliant-cut, 22.18-carat, D-color, VVS1-clarity diamond pendant with rubies and pink diamonds, which went for $2.1 million, within estimates.
Bracing against the vibrations of the jackhammer, illicit diamond miner Jefferson Ncube bores steadily into the rock face before him, sending chunks of dry stone clattering to the ground and filling the air with a cloud of pale gray dust. He’s 30 feet below the surface of the desert in the Namaqualand region of South Africa in a tunnel barely tall enough to crawl through.
“I don’t enjoy this at all, but I need the money,” says Ncube, who holds a degree in agricultural science from the University of Pretoria but says he has been unable to find work elsewhere. “I have a family to support, a wife and a 1-year-old child.”
The Nuttabooimine, near the coastal town of Kleinzee, was once mined by the diamond giant, De Beers, the largest of dozens of industrial mining operators who, for the best part of a century, formed the backbone of the region’s economy.
But over the past 20 years, rising operational costs and a dwindling supply of diamonds have made large-scale industrial mining increasingly unviable. The sector’s steady decline has left a legacy of chronic unemployment in Namaqualand but has also created opportunities for a growing number of desperate young men and women willing to tolerate hardships and dangers as they eke out a living in abandoned mines.
Known locally as “zama-zamas” — loosely, “ones who try their luck” in isiZulu — unlicensed miners like Ncube are considered illegal by the government. Yet here on South Africa’s wild and diamond-rich Atlantic coast, residents say the number of zama-zamas has burgeoned in recent years, fueled by the lack of jobs, the economic impact of the COVID-19 pandemic and the rising cost of living, as well as by political and economic crises in neighboring countries.
Earlier this year, South Africa’s minister of Mineral Resources and Energy, Gwede Mantashe, described illegal mining as a “plague” amid reports of rampant corruption, extortion and violence linked to zama-zama activity across the country, not only in relation to diamonds but also coal, and other minerals such as gold and chromite. Once confined largely to the country’s estimated 6,100 abandoned or ownerless mines, officials say illegal mining is increasingly spilling over into operational mines too.
Ncube is part of a 12-man team, all of them migrants from Zimbabwe, where hyperinflation and unemployment have made it all but impossible to build a stable life for their families. Out in the desert, living conditions are bleak and working conditions even worse, but with some basic tools and a little knowledge of geology, they manage to make ends meet. The men, almost all of whom have arrived in the past two years, share the work and split whatever profits they make.
“We dig down until we hit the bedrock, then we go sideways through this belt,” says Ncube, pointing at a band of rock and gravel on the side wall of the tunnel. “This is where we find the diamonds. In the past, they used hammers and chisels. But if you use a jackhammer, you can take out more rock and then there are more diamonds for you.”
Danger in the tunnels
The miners have little in the way of safety equipment, and their tunnels are prone to collapsing. A little more than half a mile from here, at the neighboring Bontekoe mine, a simple granite plaque in the desert commemorates the miners who lost their lives in a particularly deadly collapse in 2012. Smaller accidents occur frequently and often go unreported. Community leaders say that at least six people have died at Nuttabooi alone in the past few months.
To try to stay safe, Ncube and his colleagues make a point of leaving “pillars” at 6-foot intervals as they tunnel through the ground. But it’s an imperfect system, made harder by the fact that tunnels dug by different groups of miners often collide.
“If the hole is ‘paying,’ people get greedy and they eat away at the pillars until the whole thing is just hanging,” says Ncube. “That’s how some guys died just two holes away from here. If you get greedy you’ll die down here, and then your family will suffer even more.”
After handing over to a colleague, Ncube climbs carefully back up the vertical mine shaft and hauls himself over the edge. At the surface, in a stark, lunar landscape of craters and piles of rubble, zama-zamas cluster together around their holes, sifting through gravel and chatting over the low hum of diesel generators. A few hundred yards away, the old De Beers mine lies abandoned, a massive scar on the face of the desert, hemmed in by towering mine dumps.
“De Beers has taken all the diamonds out of Namaqualand and now we’re back in poverty,” says Andrew Cloete, a longtime illicit miner who lives in a small tent of black and red plastic sheeting in the ever-expanding squatter camp below the Nuttabooi mine. “The companies left us like they found us — with nothing. But if we just sit there thinking about it, our kids will die. So we, the diggers, come in here and take the scraps.”
The plight of the zama-zamas
There is a palpable sense of anger, particularly among the miners who grew up in Namaqualand, over how little of the region’s diamond wealth has stayed in the local area. Over several decades, vast quantities of diamonds have been exported overseas, yet most of the area’s roads are still unpaved, service provision is haphazard at best and poverty and alcoholism are endemic. Unemployment in the province stands at over 46%.
“Africa’s f***ed up. We don’t have jobs, all we have is minerals — but they’re being looted by the West,” said one miner, an unemployed mechanical engineer who didn’t want to be named, citing concerns that he may be targeted by the authorities. “This is our Africa. This is our land. These are our minerals.”
Outside Cloete’s tent, men wander through a small city of plastic lean-tos that has sprung up in the desert over the past two years. The camp has enveloped a handful of derelict buildings left behind by the mining companies, where zama-zamas now sleep side by side on filthy mattresses on the floor. The camp, home to around 1,500 people, has no electricity, running water, clinics or sanitation but a surplus of bars and taverns that do a steady round-the-clock trade.
“Nobody would live in conditions like this if there wasn’t a need,” says Cloete, gesturing toward the scene outside. “We’re here because of poverty, hunger and joblessness.”
They’re not getting rich off their diamonds
After lighting a cigarette, Cloete reaches for a small glass jar and takes out a plastic packet from inside. Carefully, he empties its contents into his palm. About a dozen small, rough diamonds tumble out. On international markets they might fetch a substantial sum, he says, but due to the illegal nature of their work, the zama-zamas have little bargaining power and are forced to sell their finds to black-market buyers for a fraction of their true value.
“They buy diamonds like they’re buying sweets,” complained one zama-zama. “You get people buying diamonds for 100 Rand [about $5.50].”
Cloete, who founded an informal group of mineral rights activists known as the “Mining Fighters,” has spent years petitioning the South African government to find a productive way to formalize zama-zama mining, a move that he says would lead to safer working conditions and a fairer marketplace for local diamonds, as well as bringing in considerable revenue for the government. Similar systems are in place in many other African countries, where so-called artisanal mining, carried out by individuals or small groups using traditional methods and basic equipment, is now a major employer and revenue generator.
The town was once the property of the De Beers diamond company. In its heyday, it was a thriving settlement of 4,000 people with about 30 recreational clubs. After closing down its mines in the region, De Beers sold off the town, which is now largely empty.
But Cloete says he has yet to receive a response. “They treat us like we’re criminals,” he says.
Many in the formal diamond sector would also like to see the legalization and regulation of informal mining, which they say hampers their legal operations and fuels a parallel black market in illegal diamonds.
“At the end of the day, it’s a situation that’s totally unbearable for us,” said Gert Van Niekerk, chairman of the South African Diamond Producers Organisation, an industry body representing legal diamond miners. “This is not the Wild West.”
Kim Cupito, who lives with her husband in a derelict building left behind by De Beers, lost her job during the pandemic. “We need to survive, and this is God’s ground. It’s for everybody,” she says.
In Kleinzee, a faded mining town once owned by De Beers, where most homes now lie empty, residents say the influx of illegal miners from around South Africa and neighboring countries has led to a rise in crime.
The uncertain future faced by zama-zamas
“Zama-zamas aren’t welcome here,” said one Kleinzee restaurateur. “They have knives, they have guns, they’re gangsters. They can come and buy things here, but afterward they must leave. We don’t want them here.”
In a policy document released in March, South Africa’s Department of Mineral Resources and Energy announced its intention to create a new police unit dedicated to combating illegal mining. It also laid out plans to make it easier for artisanal and small-scale miners to legally acquire mining rights by streamlining the expensive and time-consuming process of applying for a permit.
Police raids are frequent. In one major operation in July, a combined force of police and other law enforcement bodies backed by two helicopters and a spotter plane raided the Nuttabooi site, arresting over 100 people and confiscating 130 generators and 121 jackhammers, along with other equipment. But within days, mining activity had resumed.
But creating new legislation to support the policies could take time. And critics say it’s unrealistic to hope that many zama-zamas will voluntarily cease their activities, undergo training, comply with regulations and start paying taxes and royalties to the government, especially given that many are in the country illegally and would not be eligible for mining permits.
In the meantime, Namaqualand’s zama-zamas don’t intend to wait around.
“There’s nothing for us out there,” said Kim Cupito, a former fruit trader who lost her job during the pandemic and now lives with her husband in a derelict De Beers building with gravel piled up in the hallways and gaping holes in the roof. “We need to survive, and this is God’s ground. It’s for everybody.”
A 13.15 carat pink diamond will no longer be available at the upcoming Christie’s Magnificent Jewels auction in New York.
The emerald-cut, fancy vivid pink, VVS1 clarity stone, which carried a price estimate of $25 million to $35 million, was poised to be the December 6 sale’s showcase piece. Christie’s described the diamond as one of the largest of its kind to appear at auction.
“Christie’s confirms that the fancy vivid pink diamond ring has been withdrawn from sale in New York on December 6,” a spokesperson said. The company declined to comment further or provide a reason.
The item was scheduled to appear on display in Hong Kong on Friday. The removal was “very surprising,” said one colored diamond dealer in the municipality.
Colored diamonds have had a mixed season at auction. On November 8, the 18.18-carat Fortune Pink fetched CHF 28.4 million ($28.9 million) at Christie’s Geneva, toward the lower end of its presale estimate. The following day, a 5.53 carat diamond from the De Beers Exceptional Blue Collection failed to find a buyer at a Sotheby’s auction in the Swiss city.
With the 13.15 carat pink off the list, the top remaining item at the Magnificent Jewels sale is a pear modified brilliant cut, 31.62 carat, fancy blue diamond pendant with a price estimate of $10 million to $15 million.
A blue diamond pendant will be among the headliners in next month’s Christie’s sale in New York, where it is expected to bring in up to $15 million.
The pear modified brilliant-cut, 31.62-carat, fancy-blue stone, surrounded by white and pink diamonds, is potentially internally flawless, Christie’s said Tuesday. A pear brilliant-cut, 86.64-carat, D-color, VVS1-clarity diamond pendant will join it at the December 6 Magnificent Jewels sale. That piece, which hangs from a chain of 78 diamonds between 0.50 and 2.50 carats, is estimated at $5 million to $7 million.
Other notable items include a torque bangle bracelet bearing a heart brilliant-cut, 50.05-carat, D-color, internally flawless diamond, with a presale price of $3.7 million to $4.5 million. A modified pear double rose-cut, 5-carat, fancy-vivid-blue diamond ring has an upper estimate of $4 million and no reserve. An oval brilliant-cut, 51.60-carat, G-color, VS2-clarity diamond ring carries a high price of $2.8 million.
Christie’s will also offer an unmounted modified pear brilliant-cut, 104.04-carat, fancy-intense-yellow diamond. That jewel has an upper estimate of $2.5 million, as does a round-cornered square brilliant-cut, 107.46-carat, fancy-yellow diamond brooch by Graff. Meanwhile, an emerald-cut, 13.75-carat, fancy-vivid-yellow, internally flawless diamond ring by De Beers and an oval brilliant-cut, 2.21-carat, fancy-intense-blue diamond ring are set to fetch up to $1.8 million each.
Those items join the star of the show: An emerald-cut, 13.15-carat, fancy-vivid-pink diamond ring that Christie’s expects will fetch up to $35 million at the auction.
Petra Diamonds said on Monday it had halted operations at its Williamson mine in Tanzania after a tailings storage facility burst, causing flooding in nearby areas.
The company, which also operates three mines in South Africa, said the eastern wall of Williamson’s tailing dam was “breached”, but said in an email that the pit was not affected.
Petra noted that there were no injuries or fatalities confirmed so far, adding that the government and mine emergency response teams had been mobilized to the site.
“While no injuries have been reported, any impact on the local communities would be viewed as a material negative from an ESG standpoint,” Berenberg bank analysts said in a note.
The diamond miner has worked hard to clean up its image in Tanzania. Last year, it achieved a £4.3 million (about $4.9m) settlement with claimants alleging widespread human rights abuses, including beatings and detentions, at Williamson —the country’s biggest diamond mine.
Petra, which has repeatedly denied the involvement of its own employees in the incidents, admitted that “regrettable” incidents took place at the mine in the past.
The clashes between locals and police resulted in “the loss of life, injury and the mistreatment of illegal diggers” within the mining license, it said last year.
Watchdog World Mine Tailings Failures (WMTF) said Williamson’s is third diamond tailings failure in a year and the 19th of this decade (2015-2024).
The organization’s executive director, Lindsay Newland Bowker, noted that in terms of mineral production, this decade is already the worst in terms of catastrophic tailings failures in recorded history.
Lucara Diamond Corp.’s sales dropped in the third quarter as the company supplied fewer large and expensive stones from its lucrative Karowe mine in Botswana.
Revenue fell 31% year on year to $49.9 million, while net profit slumped 86% to $1.8 million, Lucara reported Wednesday.
Sales of rough from Karowe declined 36% to $46.5 million, with volume down 15% at 99,301 carats and the average price falling 43% to $337 per carat. The remaining revenue came from sales of third-party goods on Lucara’s Clara online platform.
Management blamed a decrease in the number of high-value diamonds the company sold to HB Antwerp through the pair’s supply agreement. The Belgian manufacturer is contracted to buy all Karowe rough of 10.8 carats or more, with Lucara receiving a proportion of the final polished proceeds.
In the third quarter a year earlier, Lucara sold four pink diamonds and two white, type IIa stones — weighing 393.5 and 257.5 carats — to HB. As a result of the unfavorable comparison, revenue from the agreement plummeted 46% to $27.1 million.
“Despite the overall decrease in revenue recognized in [the third quarter], diamond-market fundamentals continued to support healthy prices as steady demand and some inventory shortages were reported,” Lucara said. Fluctuation in the availability of 10.8-carat production is expected, it added.
Output from Karowe slid 19% year on year to 78,879 carats for the quarter.
The kimberlite cluster is located around 110km north-east of a Finsch diamond mine.
Diamond mining company Botswana Diamonds has secured a five-year prospecting licence on ground containing the Reivilo cluster of kimberlites in Barkley West, South Africa.
The kimberlite cluster is located around 110km north-east of a Finsch diamond mine owned by Petra Diamonds.
According to an exploration by the previous licence holder, the area holds a delineated a cluster of three kimberlite pipes, all within a 250m radius.
The prospecting licence is effective until June 2027.
Botswana Diamonds chairman John Teeling said: “When the ground became recently available, we immediately applied for the area.
“Botswana Diamonds management have long been aware of the diamond potential of this ground, and so we are delighted to have finally been awarded this high-profile exploration ground and look forward to updating shareholders in the near future on developments.”
Botswana Diamonds plans to finalise its exploration programme after carrying out a review of all the available data on the Reivilo cluster.
The firm said in a statement: “Samples of the drilling core produced G10 and eclogitic garnets, which are the optimal indicators for diamondiferous kimberlites.”
In July this year, Botswana Diamonds purchased an additional stake in the prospective Maibwe joint venture (JV) in Botswana.
The company holds a 51.7% stake in Siseko Minerals, which increased its stake in the JV from 29% to 50%.
At the time, Botswana Diamonds said it was involved in three companies focused on diamond exploration in Botswana, as well as owned assets in South Africa.
Maibwe currently holds 11 prospecting licences in Botswana’s area of the Kalahari Desert, which include several kimberlite pipes.
In October 2019, Botswana Diamonds received a mining permit for gravels and unprocessed stockpiles around the Marsfontein mine in South Africa via its associate, Vutomi Mining.
oronto-listed Mountain Province Diamonds will next week put on sale an “exceptional” coloured rough diamond, which it recovered from the Gahcho Kué mine, in Canada’s Northwest Territories.
The diamond, a 151.60 t octahedron of exceptional clarity, will be offered for sale alongside a selection of more than 90 individual special rough diamonds recovered from the company’s Canadian diamond mine.
The upcoming sale represents the biggest offering of +10.8 ct gem quality diamonds offered by the company to date.
“This important diamond represents a clear example of the Gahcho Kué mine’s ability to consistently recover high-quality gems of exceptionally large size. These gems are highly coveted by collectors around the globe not only for their beauty but increasingly, for their Canadian origin,” commented VP for diamond marketing ReidMackie.
The second largest internally flawless fancy vivid pink diamond to ever appear at auction was unveiled Wednesday in London by Sotheby’s. The 11.15-carat Williamson Pink Star will be sold in a single-lot auction in Hong Kong on October 5. Its estimate is $21 million.
The auction house says it has the potential to set a new per carat price record for a fancy vivid pink diamond.
“We do have the confidence that it will find a great collector and have the interest of multiple parties,” Wenhao Yu, chairman of Jewellery and Watches at Sotheby’s Asia, told Forbes on Tuesday. “It has the potential to reach a very strong price.”
He adds, “This diamond truly checks all the boxes. It has the best qualities you can have in a pink diamond.”
The current price per carat auction record for a fancy vivid pink diamond is $2,656,909 for the 18.96-carat Winston Pink Legacy, sold in 2018 by Christie’s Geneva. The largest internally flawless, fancy vivid pink diamond offered at auction is the 59.60-carat CTF Pink Star. It was sold by Sotheby’s Hong Kong in 2017 for $71.2 million, a world record for any gem or jewel sold at auction.
Yu compares the Williamson Pink Star to an exceptional work of art.
“We timed this lot to be offered between Sotheby’s modern and contemporary art auctions. That’s because instead of offering just another important diamond, we view this diamond as a work of art from mother earth and a wonder of nature,” Yu says. “It’s comparable to a Monet or a Picasso and is even more rare.”
The Williamson mine is one of the oldest operating diamond mines in the world, famous for producing what is described as “bubblegum” pink diamonds, according to the auction house. One of the best-known diamonds from the mine is the 23.6-carat Williamson Pink Diamond fashioned into a brooch by Cartier and owned by Queen Elizabeth II.
“We wanted to relate the important provenance of the Williamson mine when naming the diamond,” Yu says. “The unique saturated pink color is one of the important qualities of diamonds from this mine. It is an honor for us that after so many decades another important pink diamond comes from the Williamson mine and we can offer it at auction.”
The cushion-shaped diamond was crafted from a 32.32-carat rough diamond by Diacore, a diamond manufacturer that specializes in crafting rare, exceptional fancy-colored diamonds. The company purchased the gem in late 2021 for $13.8 million. Yu says crafting the diamond is just as important as discovering it, and Diacore is one of the few companies in the world capable of cutting and polishing such an important gem.
“Not every rough can yield a diamond of this high quality so we should also give credit to Diacore,” he says. “They really made cutting and polishing into an art. They are very skilled and experienced with the best technology and a lot of courage. It’s rare to have a vivid pink color. It’s rarer when it’s over 10 carats and even more rare if it’s internally flawless. It’s luck to find this kind of diamond that was formed underground for millions of years, and it takes a great amount of art and creativity to fashion it into a gorgeous stone with so many exceptional qualities.”
Pink diamonds are among the rarest colors to occur naturally in diamonds. Of all the diamonds submitted to the Gemological Institute of America (which analyzes and grades diamonds), fewer than 3% are classified as colored diamonds, and fewer than 5% of those are considered predominantly pink.
The Argyle Mine in Australia, before it was retired in 2020 after exhausting its supply of gem-quality diamonds, produced more than 90% of the world’s pink diamonds. The absence of pink diamonds from this mine makes important pink diamonds like the one being offered even more rare, Yu says.
“Pink diamonds are still growing in demand in the market, and this now makes the Williamson Pink Star even more sought after,” he says.
The diamond is being presented in an 18k gold ring flanked by trapeze-cut diamonds and embellished with brilliant-cut diamonds.
London is the first stop where the diamond will be viewed by the public. It will then travel to Dubai, Singapore and Taipei before the final viewing and sale in Hong Kong.
