The Evolution of De Beers’ Strategy

A portrayal of De Beers’ operations past and present.

Bruce Cleaver reflects on the changes that took effect in the six years he headed the diamond company.

RAPAPORT… Bruce Cleaver had a very focused “to do” list when he took over as De Beers CEO in July 2016. Having previously worked on strategy and business development at the company, as well as at parent Anglo American, he recognized De Beers’ need to evolve, and to protect it from the increasing volatility evident in the global economy and diamond market.

“I wanted to build a more sustainable business; one that was less prone to economic cycles,” Cleaver stresses in an interview with Rapaport News. “I wanted to ensure we’d never get caught in the position we had in 2008 when we hit a very serious downturn and our balance sheet was very stretched.”

He never imagined those goals would be challenged by a global pandemic and a war in Ukraine that has brought sanctions on Russian diamonds — approximately one-third of global rough supply. These aren’t events you predict in your risk analysis, he notes.

In contrast to 2008, when De Beers had to take on more debt to weather the financial crisis, the company emerged from Covid-19 stronger than before, and it may even have benefited from the limitations on Russia-based Alrosa — its biggest competitor. The $491 million in underlying earnings it reported in the first six months of 2022 was its best half-year profit since 2011, and the $3.54 billion in revenue its highest since 2014 (see graph).

But Cleaver looks beyond the financials as he reflects on his tenure at the helm of the world’s largest diamond company. His six-and-a-half-year stint brought a significant transformation to De Beers’ structure, brand positioning, messaging, and relationships, all of which he believes demonstrate transparency and a willingness to change that were not always evident at the company.

Call to collaborate

His first public statement after being appointed to the position called for greater cooperation and partnerships within the trade. He actively sought to ease the tension that often stood between De Beers and sightholders and at times its government partners, he admits.

“It was important for us to show people we would change, listen more and collaborate more,” he reflects. “I do feel there is much more trust now than before, and a sense of working toward a common goal — that we can agree to disagree in a more friendly way.”

Central to achieving that was the refurbishment of the sightholder application process, which he concedes had previously been complicated and intimidating. The current system further demonstrates De Beers’ willingness to be more open and transparent, Cleaver insists. It’s a complicated task, he adds, considering the company distributes some 33 million carats a year and must set criteria to award goods to certain people and not to others.

The sheer volume of De Beers’ production means the company is unlikely to shift away from the sight system any time soon. However, it did tweak its distribution at the beginning of 2022 to provide more bespoke supply by classifying sightholders according to their business type: manufacturer, dealer, or retailer. The move was seen as an attempt to reduce the flipping of boxes on the secondary market and to bring more efficiency to the supply chain.

Special stones to sell

There has been speculation that the Botswana government — a 15% shareholder in De Beers and a joint venture partner in its mining and selling distribution businesses — is pressuring the miner to sell its specials through the parastatal Okavango Diamond Company, in vertically integrated deals with manufacturers. The two are currently negotiating a new 10-year supply deal and the renewal of De Beers’ mining licenses in the southern African country.

Structuring supply in such a way would see the company (and government) take a share of profit from the sale of the resulting polished. Smaller companies have struck similar partnerships, such as Lucara Diamond Corp.’s agreement to sell its 10.8-carat-plus rough through manufacturer HB Antwerp.

Cleaver notes the deeper considerations with which De Beers must contend. “It’s a whole different ball game selling 33 million carats a year than 50,000 carats. We have an offering that we must sort, value, sell, trace and track on a completely different scale,” he points out. “You have to be much more sophisticated, more thoughtful and have a much stronger balance sheet.”

That’s not to say the company is set in its ways, particularly regarding how it sells specials. Last year, it partnered with sightholder Diacore to buy an exceptional 39.35-carat blue rough stone from Petra Diamonds for $40.2 million and share in the profit from the polished. The De Beers Blue, the 15.10-carat, fancy-vivid-blue polished that resulted from that rough, fetched $58.7 million at Sotheby’s Hong Kong. The two companies also teamed up to buy five blue rough diamonds from Petra in 2020, with the resulting polished stones expected to garner over $70 million at Sotheby’s in November (after press time) and December.

“It’s not difficult as a seller of a small volume of goods to find one buyer who will buy one particular stone at a significant premium to the market — that happens to us all the time,” he adds. “We just don’t publicize it.”

Tech at play

Technology has been the central tool to improve the way De Beers sells rough, Cleaver underlines. He teases that the company will introduce various innovations in the next 12 to 18 months that will be “game changers in how we continue to sell in this evolving market,” but he declined to reveal further information about these developments.

Data is also playing a much more important role in enabling De Beers, and others, to make more rapid decisions than before — and that data-centric strategy is being driven by technology, he notes.

In fact, technology is influencing change across all De Beers business units, Cleaver says. That includes at its mining operations, where it is tackling the challenge to “mine more gently,” using less water and energy to be more environmentally friendly. He also highlights the Tracr program — De Beers’ blockchain-driven traceability platform — which is gaining traction and will enable companies to show the provenance of their De Beers supply.

Building forever

That all feeds into the strong focus on sustainability that De Beers has adopted in recent years and the need to show one’s diamond is ethically sourced. While Cleaver recognized the need to talk about sustainability early in his tenure as CEO, the rapidness with which the subject became a focal point for brands surprised even him.

“I wanted to make sustainability a bigger issue, but I don’t think I realized at the beginning just how important it is,” he admits. “Now ‘Building Forever’ is an absolutely key part of everything we do.”

Building Forever outlines 12 goals De Beers has set to achieve by 2030, encompassing four areas it has identified to make a meaningful impact.

Those are leading ethical practices, partnering for thriving communities, protecting the natural world, and accelerating equal opportunity. “These are vitally important not only to our business, but also to our employees, partners and communities across all facets of our operations,” the company emphasizes on its website.

The program gradually emerged as the core message of the De Beers brand, taking its cues from the rising awareness among millennials and Gen-Zers on issues such as carbon neutrality, climate change, and social upliftment. The program is what distinguishes De Beers, and it provides an opportunity to maximize the value of the brand that was not apparent five years ago, Cleaver says.

Cleaning the mess

The evolution of that message paralleled Cleaver’s advocating for more brands across the industry as well as cleaning up and strengthening the De Beers brand. Key to that development was taking full ownership of its name in early 2017, when it bought the 50% of De Beers Diamond Jewellers (DBDJ) that was owned by LVMH.

“It always felt messy having the De Beers name co-owned by someone else,” he observes. “I’m very pleased we’ve been able to unify the brands into one master brand.”

The company sought to leverage its strong name recognition as much as possible. Most notably that played out at retail with the LVMH deal and subsequently renaming the retail operation De Beers Jewellers (DBJ). It also rebranded Forevermark as De Beers Forevermark, and the strategy extended beyond its retail operations to align the whole group into one “De Beers” corporate identity with a common goal.

“I wanted to define a more holistic business strategy: to run the company as one business rather than three separate silos,” Cleaver shares. “I think we’ve been pretty successful in achieving that.”

Staying brilliant

De Beers previously had a more vertical structure, split between the pillars of mining, rough sales and its retail brands. Over the past half decade, it has morphed into a more integrated end-to-end business with every employee, regardless of which area of the company they work, having the same stated purpose: to “make life brilliant,” Cleaver explains.

As such, the outgoing CEO carefully defines De Beers as a “natural-diamond company” with an integrated structure that encompasses exploration, mining, rough sales, and retail brands. Lightbox, the company’s lab-grown business, is considered an “adjacency” that doesn’t fit into the core business model, he insists.

With that structure in place, Cleaver is confident the company can double-down on innovation – as he claims it did with Tracr and Lightbox — strengthen its relationships with the trade and government, and in doing so, lead the industry on big issues such as sustainability. He hopes to continue to influence that path in his new role as cochairman, through which he will take an active role in engaging with external stakeholders.

“It’s important that De Beers pushes agendas and ideas that might be surprising they came from a big organization,” Cleaver discloses. “But when you look at some of the sustainability work done by retailers and sightholders today, it’s fantastic, and I think that we did have some small influence on that — that was all deliberate.”

The industry will continue to evolve because the world will continue to change quickly, he continues. “I’ve tried hard to always think about what the next trend or the next move should be — and why shouldn’t it be us who makes them? We recognize that when De Beers talks, people do listen,” he concludes.

De Beers Blue Diamond Fails to Sell at Sotheby’s

5.53 carat De Beers blue diamond
5.53 carat De Beers blue diamond

A blue diamond weighing 5.53 carats failed to find a buyer at Sotheby’s Geneva on Wednesday despite being billed as the star of the auction.

The cushion brilliant-cut, fancy-vivid-blue diamond is part of an eight-piece group called the De Beers Exceptional Blue Collection, which Sotheby’s has spread between its various Magnificent Jewels sales. No bids matched the stone’s threshold price for sale, according to a post-auction report by the Fancy Color Research Foundation (FCRF). The piece carried a presale estimate of $11 million to $15 million.

“The blue is an exceptional stone in every sense,” Sotheby’s told Rapaport News Thursday. “It attracted significant interest prior to yesterday’s sale. While we didn’t get to see it sell in the room last night, we are confident it will find a new home very soon.”

Meanwhile, a number of items set records at the November 9 sale, including a 20.16-carat sapphire and diamond ring from Cartier. That piece, which fetched $2.8 million against a high estimate of $2 million, saw a record price per carat for any blue sapphire of Burmese origin ever sold at auction. A 20.58-carat, pink sapphire ring also broke the record for per-carat price, bringing in $1.9 million, or $91,690 per carat, well above its $808,368 upper price tag. A pink sapphire and diamond brooch weighing 92.01 carats by Jean Schlumberger sold for $1.8 million, outstripping its $505,278 high estimate and setting a record price for a piece of jewelry by the designer.

Another notable item at the sale was a pair of unmounted oval-cut, D-flawless diamonds weighing 20.03 and 20.19 carats. The duo fetched $4.2 million, within estimates. A step-cut, 33.13-carat, D-color, VVS1-clarity diamond ring by Cartier brought in $2.9 million, also within its expected range.

The entire Geneva Magnificent Jewels auction garnered $50 million. Sotheby’s will offer two more blue diamonds from the De Beers collection at its upcoming New York Magnificent Jewels sale on December 7.

Lucara Sales Fall Amid Lack of High-Value Diamonds

Lucara Diamonds – Karowe Diamond Mine

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.

Debswana posts 37.5% jump in 9-month diamond sales

Debswana Diamond Company

Rough diamonds sales by Debswana Diamond Company jumped 37.5% in the first nine months of 2022, statistics released by the Bank of Botswana showed Tuesday, driven by steady demand for jewellery.

A joint venture between Anglo American unit De Beers and Botswana government, Debswana sells 75% of its output to De Beers with the balance taken up by state-owned Okavango Diamond Company.

Debswana’s January-September sales rose to $3.578 billion from $2.602 billion a year earlier, data from the central bank showed.

In Botswana’s pula currency, Debswana’s rough diamond sales rose 52.5% to 43.237 billion pula reflecting a stronger dollar in the period.

In dollar and pula terms, the nine-month sales top the company’s full-year results in 2021 when sales totalled $3.466 billion and 38.134 billion pula.

Debswana accounts for almost all diamonds produced in Botswana with Lucara’s Karowe mine being the only other operating diamond mine in the country.

Botswana generates about 30% of its revenue and 70% of its foreign exchange earnings from diamonds.

However, De Beers sees the risk of the market slowing down in the coming months due to a deterioration in global economic conditions, reduced consumer spending and continued Chinese covid-19 lockdowns.

“In line with normal seasonal trends, we anticipate that sales in the final quarter of the year will be affected by the normal temporary closure of cutting and polishing factories for the religious holidays in India,” parent firm Anglo American said last week.

De Beers Eases Buyer Terms Amid Market Slowdown

A rough diamond under analysis

De Beers will offer widened concessions to purchasers of larger rough diamonds at its upcoming sight as trading has slowed amid difficult market conditions.

The miner will increase its “buyback” allowance to 20% for 1-carat goods and up at the sale, which begins later this month, industry insiders told Rapaport News this week.

Buybacks are a mechanism enabling sightholders to sell 10% of stones back to De Beers after making their purchases. They are popular among clients when markets are weak, as customers can handpick the least profitable items and hope the miner will offer a good price. For De Beers, they provide a way of promoting sales without reducing prices.

Lockdowns in China and global economic uncertainty have spooked sections of the industry, with De Beers’ move reflecting a split in the market. Companies that usually buy 1-carat and larger rough destined for the Far East have reduced their purchasing, while top US and European brands continue to buy melee, supporting the trade in rough under 0.75 carats, dealers explained. In that context, the miner will maintain its usual 10% buyback allowance for rough under 1 carat.

“People actually did buy a lot [of the larger items] up till June [or] July this year, when they thought China would slowly start opening up again,” a market participant said. “That clearly hasn’t happened, and there are people now sitting on those goods.”

Sightholders are expecting De Beers’ next sales cycle — its ninth of the year — to bring the miner around $400 million after buybacks, compared with $500 million in September. The sight will run from October 31 to November 4. The December sight is also likely to be relatively small as southern African cutting factories shut for the holidays.

The October sight will take place amid the Diwali season in India, for which manufacturers are expected to implement extended production pauses of up to three weeks because of the sluggish market. Many of them have been trying to slash their inventories ahead of the holiday.

“De Beers is not too eager to reduce prices at this stage. I think they want to wait till early 2023 for that,” a sightholder predicted.

De Beers has released its sales schedule for next year, with the miner holding its usual 10 sights across the 12-month period.

The miner sells most of its rough to sightholders through a contract system under which clients make certain purchasing commitments in return for consistent supply. In April 2021, the miner introduced a new sales agreement offering more bespoke supply for manufacturers, dealers and retailers. Alrosa, which operates a similar system, has not yet published a 2023 schedule on its website.

The dates for De Beers’ sights in 2023 are as follows:

• Sight 1: January 16 to 20
• Sight 2: February 20 to 24
• Sight 3: March 27 to 31
• Sight 4: May 2 to 5
• Sight 5: June 5 to 9
• Sight 6: July 10 to 14
• Sight 7: August 14 to 18
• Sight 8: September 18 to 22
• Sight 9: October 23 to 27
• Sight 10: December 4 to 8

Collection of Blue Diamonds to Fetch Over $70M

The eight De Beers blue diamonds.
The eight De Beers blue diamonds.

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.

Botswana Diamonds licensed for South African kimberlite cluster

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.

11.15-Carat Internally Flawless Pink Diamond Could Fetch $21 Million

11.5-carat Williamson Pink Star diamond 

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.
