Sotheby’s will sell a group of eight fancy-blue diamonds from De Beers across its global Magnificent Jewels auctions, expecting the set to bring in more than $70 million.
The stones are cut in various shapes and range from 1.22 to 11.29 carats, with a total weight of 32.09 carats, Sotheby’s said last week. The polished originates from five rough blues that De Beers and Switzerland-based manufacturer Diacore purchased jointly from Petra Diamonds in November 2020. Diacore cut and polished those stones into eight diamonds over the past two years.
Sotheby’s will offer three stones from the eight-piece group, called The De Beers Exceptional Blue Collection, this year. The first, a cushion brilliant-cut, 5.53-carat, fancy-vivid blue diamond will go under the hammer at the Magnificent Jewels and Noble Jewels sale in Geneva on November 9, with a high estimate of $15 million. Meanwhile, the December 7 Magnificent Jewels sale in New York will feature a cushion brilliant-cut, 3.24-carat, fancy-vivid blue, internally flawless diamond estimated at up to $8 million. That jewel will be joined by a cushion-cut, 2.08-carat, fancy-intense-blue diamond with an upper price tag of $1.5 million.
“I have remained in awe of the De Beers Exceptional Blue Collection since the first moments I set eyes on it,” said Olivier Wagner, head of Sotheby’s Magnificent Jewels auctions in Geneva. “The market for colored diamonds and precious gemstones has never been stronger. [The diamonds] will, I am sure, captivate all collectors of exceptional gemstones.”
Sotheby’s will sell the remaining five diamonds at its spring 2023 Magnificent Jewels auctions. Those include a step-cut, 11.29-carat, fancy-vivid-blue estimated at up to $50 million; a step-cut, 4.13-carat, fancy-intense-blue expected to go for up to $3.5 million; and a cushion brilliant-cut, 3.10-carat, fancy-vivid-blue diamond with a high price of $5 million.
In April, Sotheby’s sold another De Beers blue diamond: a step-cut, 15.10-carat, fancy-vivid-blue, internally flawless stone that went for $57.5 million in Hong Kong.
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.
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 Pink Star is the second largest internally flawless fancy vivid pink diamond
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.
Diamond is a naturally occurring rare mineral that is composed of pure elemental carbon. Due to the extremely rigid arrangement of the carbon atoms in a crystal structure, diamonds possess the maximum hardness and thermal productivity than any natural material. Diamonds are also in high demand as gemstones and as luxurious commodities. Despite having a reputation for being used in jewelry like rings and necklaces, 80% of mined diamonds are used for research and industrial purposes because of their toughness and shine.
The hardest substance known to man, diamonds, are frequently used to drill, grind, or cut other difficult materials. Initially, its reserves were only discovered in Africa and provided to the rest of the globe, but today, exploration and production of diamonds have also begun on other continents. Currently, Russia produces 30% of the world’s diamonds, and approximately 39.12 million carats of diamonds were produced in Russia in 2021, making it by far the greatest diamond-mining nation in the world. With a production of 22.9 and 17.6 million carats of diamonds, respectively, Botswana and Canada are placed in second and third place, followed by the Democratic Republic of the Congo and South Africa.
1. Russia (39.12 Million Carats)

Russia presently leads the world in diamond output after it began mining in 1947. Regarding volume, it is also the top exporter of rough diamonds worldwide. ALROSA is Russia’s largest diamond miner, maintaining a virtual monopoly over the sector and producing over 90% of the nation’s annual output. Russia houses some of the world’s greatest mines and diamond reserves (some of which have not yet been explored), including Udachny, Grib, and Aikhal. It was revealed in 2014 that Alrosa intends to expand the Udachny mine into a 5 million carat per year project, making it the most significant diamond mine in both Russia and the entire globe. Alrosa first used Udachny in 1971, and during the following 43 years, it has helped the company make over $80 billion. Alrosa should be able to keep its position as the world’s biggest diamond producer by volume for the foreseeable future due to Udachny’s figures.
2. Botswana (22.88 Million Carats)

A significant diamond mine was found in 1966, the year Botswana declared its independence from Britain, in a rural region called Orapa, about 250 miles from the nation’s capital of Gaborone. De Beers, the firm that discovered the mine, was and still is the world’s largest supplier of “rough stones.” The two most significant of the seven mines in the country are Orapa and Jwaneng. Despite ranking second in terms of volume, Botswana tops the list of the world’s top producers of diamonds. Botswana, which was one of the world’s 25 poorest nations, has achieved upper-middle income status due to the revenue from diamonds. The nation is currently vying for a more significant position in the sector as the No. 1 player Russia faces condemnation from around the world for its invasion of Ukraine.
3. Canada (17.62 Million Carats)

The Northwest Territories, which were once used as hunting grounds, are now used mainly for large-scale resource extraction, including diamond mining. Diamonds weren’t found by non-natives until 1991, specifically by two geologists named Chuck Fipke and Stewart Blusson. The first diamond mine in the Northwest Territories, known as Ekati, opened in 1998 because of this finding. The Arctic Canadian Diamond Company presently oversees the operation of Ekati, which is a responsible steward of the environment and a significant source of high-quality employment and money for the area. Most of Canada’s diamonds are mined in the Northwest Territories, which comprise about 40% of the total geographical area. There are currently four working diamond mines in Canada, three in the NWT – the Ekati, Diavik, and Gahcho Kué mines – and the Renard diamond mine in Quebec.
4. Democratic Republic Of The Congo (14.09 Million Carats)
The Democratic Republic of the Congo is the country that turned South Africa’s diamond industry profitable. Miniere de Bakwange (MIBA), a joint venture between the Belgian business Sibeka and the DRC government, which controls 80% of the company, is the only commercial diamond producer in the DRC. Although ongoing political unrest has caused production to fall recently, the DRC has the capacity to produce more diamonds. Only a tiny area has been examined, and mining has only ever been done on a small basis. Most of the DRC’s output is mined by the informal sector rather than mining companies. De Beers markets about one-third of Sibeka’s production and holds a 20% stake in the company.
5. South Africa (9.72 Million Carats)
Historic Kimberley Diamond mine in Kimberley, South Africa.
Almost all the modern diamond trade originates in South Africa. The earliest diamonds found in South Africa were alluvial diamonds. Diamonds were initially discovered in yellow earth in 1869, and then later below ground in hard rock called blue ground near and in what would become Kimberley in the Northern Cape, the diamond center of the world. Later, the blue rock was given the mining town’s name: kimberlite. One of the country’s biggest diamond deposits is located in the South African province of Gauteng. As the government and miners continue to find significant diamond resources and pipelines, the demand for diamonds in South Africa is anticipated to rise.
One can therefore expect the global diamond industry to keep expanding and displaying a bright future as long as economic prosperity continues to improve and as long as there are still diamond reserves that have not yet been mined.
India, which cuts or polishes about 90% of the diamonds sold in the world, is ramping up sales of laboratory-made gems as demand from the US surges and they become more accepted in other markets.
Exports of polished lab-grown diamonds may double in the current financial year started April 1 from $1.3 billion in the prior year, Vipul Shah, vice chairman of the Gem & Jewellery Export Promotion Council, said in an interview. “We have a huge potential to grow exports to $7 billion-$8 billion in the next few years on the back of US demand and acceptability in the UK and Australia,” he said.
“It is going to be treated as a fashionable jewelry, which is affordable to the youngsters, and that’s the way the market is going to shift,” Shah said.
Diamonds grown in labs represent a small portion of the market currently — India shipped nearly $24 billion of polished diamonds mined naturally last year. Still, the much cheaper variety has been growing its share as it has the same physical characteristics and chemical makeup as mined stones, with experts needing a machine to distinguish between synthesized and mined gems.
Lab-made diamonds are developed from a carbon seed placed in a microwave chamber and superheated into a glowing plasma ball. The process creates particles that crystallize into diamonds in weeks.
Exports of polished lab-grown diamonds from India jumped about 70% in the April-July period to $622.7 million, while those of cut and polished mined diamonds fell around 3% to $8.2 billion during the same period, GJEPC data showed.
One advantage of the man-made gem is that it has a tracking system that helps monitor the supply chain and maintain consumer confidence in the gems.
“Commercial gem-quality earth-mined diamonds are being replaced completely by lab-grown diamonds,” said Ritesh Shah, director at ALTR, one of the first global lab-grown brands to start business in India. The product’s affordability, low carbon-footprint, size and fine quality offer a big draw for buyers, with the US the front-runner in the shift in consumer behavior, he said.
From a handful of companies growing diamonds in labs in the mid-2000s, there are now about 25 such growers in India, he said. The country contributes about 15% of the global production of lab-grown diamonds, according to the GJEPC.
Signet Jewelers has signed a deal to acquire online retailer Blue Nile for $360 million in cash.
The purchase will boost Signet’s bridal, “accessible luxury” and digital businesses, while expanding the group’s consumer base, the US retail chain said Tuesday. The company expects to complete the transaction in the third fiscal quarter, which runs until late October. Either side can pull out if the deal hasn’t closed by November 3, 2022.
“Blue Nile brings an attractive customer demographic that is younger, more affluent, and ethnically diverse, which will broaden our customer-acquisition funnel,” Signet added.
The announcement comes around two months after Blue Nile revealed plans for a stock-market flotation via a merger with Mudrick Capital Acquisition Corporation II, a special-purpose acquisition company (SPAC). The proposed deal valued Blue Nile at $873 million. Mudrick was not immediately available for comment on how that transaction progressed. The current owners are Bain Capital Private Equity and Bow Street, which acquired the e-commerce jeweler for around $500 million in 2017.
Blue Nile’s sales exceeded $500 million in 2021, according to Signet, which has stated its intention to reach total annual revenues of $9 billion in the coming years. Last October, it agreed to acquire Diamonds Direct USA for $490 million; in 2017, it bought diamond retail website James Allen for $328 million.
“By joining Signet, we will extend our premium brand and fine-jewelry offering to millions of new customers while bringing new capabilities to our leading e-commerce business that will drive additional growth opportunities for Blue Nile,” said Blue Nile CEO Sean Kell.
Meanwhile, Signet has reduced its sales guidance for the second quarter, which ended in late July, estimating revenue of $1.75 billion compared with an earlier forecast of $1.79 billion to $1.82 billion. Management cited “heightened pressure on consumers’ discretionary spending and increased macroeconomic headwinds.”
“We saw sales soften in July as our customers have been increasingly impacted by rapid inflation, so we’re revising guidance to align with these trends,” said Signet CEO Gina Drosos. The new outlook for the quarter still translates to a sales increase of around 25% compared with the equivalent period of 2019, before the Covid-19 pandemic, the executive noted.
Diamonds recovered at the Star-Orion South project.
There are few things that are more alluring and exciting than a diamond — but one of them is a significant new diamond discovery. Now those are truly rare.
In Canada, we haven’t had a significant diamond discovery for years — and the current lack of spending on exploration makes one less likely to happen in the future.
Globally, exploration for diamonds has nearly ground to a halt. In Canada last year, coal exploration attracted more spending than diamond exploration ($61 million vs. $50 million), which fell 21% from the previous year, hitting a 20-year low.
Adding to this downward momentum, in June, Rio Tinto suddenly pressed pause on its 75%-owned Fort à la Corne (Star-Orion South) diamond joint venture in Saskatchewan. After pouring more than $180 million over the past six years into a bulk-sampling program and other work to evaluate the project, Rio Tinto told JV partner Star Diamond it would not be spending more money this year “beyond what is necessary for care and maintenance.” Star Diamond, which holds 25% of the large but low-grade project, said that Rio also advised that it “intends to conduct a near-term review of its alternatives regarding the project, including its potential exit.”
It’s not clear yet what Rio Tinto will ultimately decide to do. But further investment, rather than pulling back, would have given the sector a much-needed shot in the arm. And the company, which saw its Argyle mine in Australia close in late 2020, certainly needs to replace that production and would be motivated to make the project work, if possible.
While the diamond trade and diamond prices were devastated by the pandemic, prices have made a strong comeback (in part benefiting from uneven efforts globally to avoid purchasing diamonds mined by Russia’s Alrosa). De Beers reported a 58% rise in its average selling price to US$213 per carat for rough diamonds in the first half of the year, and its rough price index rose 28% compared to the same period of 2021.
That’s not likely to help revive exploration immediately, however.
The fact is that there have been too many surprises in diamond development around the world, which have shattered investor confidence.
De Beers’ revenue rose 24% in the first half of 2022, but the miner gave a more somber outlook for the rest of the year.
“We can only have strong rough sales if that’s also coupled by what’s going on on the polished side,” De Beers chief financial officer Sarah Kuijlaars told Rapaport News on Thursday. “The polished position was very strong in the beginning of the year, but it has leveled off. We have much more caution about the next six months than we’ve had for the previous six months.”
Revenue jumped to $3.6 billion in the first half as strong consumer spending during the 2021 holiday season led to intense restocking in early 2022, parent company Anglo American reported the same day. Underlying earnings gained 84% to $491 million.
Rough sales grew 27% to $3.3 billion from five sights during the period. The remaining revenue relates to other businesses such as the company’s consumer brands and industrial-diamond business.
The miner’s rough-price index, which measures like-for-like prices, rose 28% compared with the same period of 2021. The average selling price for rough surged 58% to $213 per carat, reflecting the market upturn and a shift in the product mix to higher-value goods. Sales volume fell 20% to 15.3 million carats.
The higher average price resulted from the introduction of the new Benguela Gem mining vessel off the Namibian coast, which enabled the extraction of more lucrative stones, Kuijlaars explained. In addition, production at the Venetia deposit in South Africa was focused on the final cut of the open-pit mine, which has a relatively high grade — the number of carats per tonne of ore — and high quality, the executive added.
De Beers’ results painted a complex picture of the market. Last week, the company raised its production plan for the full year in response to strong demand, predicting output of 32 million to 34 million carats. It also noted that the sanctions and boycotts targeting Russian diamonds, as well as growing interest in provenance initiatives, would “underpin” demand for its goods. The sixth sales cycle of the year, which took place earlier this month, brought in proceeds of $630 million — 23% higher than for the equivalent period a year ago.
However, inflation in the US and lockdowns in China have created concerns across the industry.
“This time last year, our operation was coming out of Covid-19 [during which output slumped],” Kuijlaars pointed out. “To stabilize our production has been really important, and that strong production gives us confidence for the full year. That’s our part in delivering reliable supply. As we sell that through, we are very alert to signs of any slowdown in the remaining four sights of the year.”
The Gemological Institute of America (GIA) has begun accepting submissions for a new service providing consumers with source verification for diamonds.
Leading manufacturers sent the first polished diamonds to the GIA’s Source Verification Service in early July, the institute said Wednesday. GIA-graded diamonds with confirmed origin information will be available to consumers when the initial submissions are returned and as more manufacturers join the program, the organization explained.
An independent auditing firm will vet all cutters before they enter the program. The auditors will confirm the company has the ability to track a diamond from receipt of the rough through the entire manufacturing process. The GIA will evaluate all participating firms regularly to ensure they are continuing to adhere to the guidelines, it noted.
Initially, the GIA will accept only polished natural diamonds with verified source documentation, including Kimberley Process (KP) certificates and invoices from vetted manufacturers. It will add lab-grown diamonds to the service in the near future. Consumers can access the information through the GIA’s online Report Check service, it added.
“GIA’s new service provides diamond-source information to consumers as quickly as possible,” said its CEO, Susan Jacques. “The GIA Source Verification Service is ready to provide verified diamond-source information to address increasing consumer demand and government interest in transparency and traceability across the supply chain.”
Lucapa Diamond Company has recovered one of the largest pink diamonds in history: a 170-carat stone from the Lulo mine in Angola.
The type IIa rough, named the Lulo Rose, is “believed to be the largest pink diamond recovered in the last 300 years,” Lucapa said Wednesday. It is also the fifth-largest diamond from Lulo, and the deposit’s 27th over 100 carats since commercial production began in 2015. Lucapa plans to sell the diamond through an international tender conducted by Angolan state diamond-marketing company Sodiam, it noted.
“The record-breaking Lulo diamond field has again delivered a precious and large gemstone, this time an extremely rare and beautiful pink diamond,” said José Manuel Ganga Júnior, chairman of the board of state-owned Endiama, one of Lucapa’s partners in the deposit. “It is a significant day for the Angolan diamond industry.”
In addition to the pink, Lulo is also the source of Angola’s largest diamond, a 404-carat rough named the 4th February Stone.
Lucapa has begun bulk sampling at “priority kimberlites” as it searches for the primary source of Lulo’s diamonds, managing director Stephen Wetherall added.
