From an $18 Billion Giant to a $1 Billion Sale: The Rise and Reinvention of De Beers

 

For more than a century, De Beers was the undisputed leader of the global diamond industry. It transformed diamonds from a relatively rare luxury into the world’s most desired gemstone, creating the modern diamond market through visionary marketing, strict supply management and consumer confidence.

Today, that same company may be sold for as little as US$1 billion, marking one of the most remarkable reversals in the history of the luxury goods industry.

Anglo American Nears Historic Sale

Mining giant Anglo American is reportedly close to selling De Beers as it continues its restructuring following the failed takeover attempt by BHP in 2024.

According to reports, the preferred bidder is the Global Diamond Consortium (GDC), led by former De Beers Chief Executive Gareth Penny and backed by the governments of Namibia and Angola.

The proposed agreement would see GDC pay approximately US$750 million upfront, followed by a further US$250 million at a later stage. Additional performance-based payments may also form part of the final transaction, although negotiations remain ongoing and no final agreement has yet been reached.

The consortium also intends to inject approximately US$500 million into De Beers following the acquisition to strengthen operations and refocus the company on the mining and marketing of natural diamonds.

A Dramatic Fall in Valuation

The potential sale price is extraordinary considering De Beers’ former worth.

When Anglo American acquired the Oppenheimer family’s remaining stake in 2011, the transaction valued De Beers at nearly US$13 billion. During its strongest years, analysts estimated the company’s value exceeded US$18 billion.

However, a combination of falling rough diamond prices, weak Chinese luxury demand, changing consumer spending and the rapid emergence of laboratory-grown diamonds has dramatically reduced profitability across the sector.

Anglo has written down the value of De Beers three times in just three years, reducing its book value to approximately US$2.3 billion earlier this year.

The Company That Built the Modern Diamond Industry

While today’s headlines focus on declining valuations, they should not overshadow De Beers’ extraordinary contribution to the global diamond trade.

Few companies have influenced an entire industry as profoundly.

Throughout most of the twentieth century, De Beers controlled the overwhelming majority of the world’s rough diamond supply. Through the Central Selling Organisation (CSO), it managed production, stabilised prices and created confidence that diamonds would retain their value.

Perhaps even more influential was its marketing.

In 1947, De Beers launched the now legendary slogan:

“A Diamond Is Forever.”

That simple phrase fundamentally changed consumer behaviour.

It established the diamond engagement ring as the global symbol of love and commitment and remains one of the most successful advertising campaigns ever created.

For decades, De Beers also invested heavily in consumer education, retailer training, grading standards and worldwide promotional campaigns that helped grow demand across Europe, North America, Japan and later China.

Without De Beers, the global diamond jewellery market as we know it today would likely never have existed.

Botswana Remains Central

Any transaction must also satisfy the Government of Botswana, which owns 15% of De Beers and jointly owns Debswana, the partnership responsible for producing most of Botswana’s diamonds.

President Duma Boko has previously expressed interest in increasing Botswana’s ownership of De Beers, although recent reports suggest the country may instead accept a larger minority stake.

Botswana remains one of the world’s most important diamond-producing nations, and its future relationship with De Beers will be crucial to any successful acquisition.

Gareth Penny Returns

Leading the proposed acquisition is Gareth Penny, who served as Chief Executive of De Beers between 2006 and 2010.

During the Global Financial Crisis, Penny successfully guided the company through one of the most difficult periods in diamond history by temporarily suspending mining operations, reducing supply and securing approximately US$1 billion through a rights offering.

His return signals an intention to restore De Beers’ focus on natural diamonds while adapting to today’s very different market conditions.

Milestones in De Beers History

1888 – Cecil Rhodes consolidates South African diamond mining companies to form De Beers Consolidated Mines.

1934 – The Diamond Trading Company is established, laying the foundations for centralised rough diamond distribution.

1947 – The iconic slogan “A Diamond Is Forever” is created by advertising agency N.W. Ayer, forever changing the jewellery industry.

1950s–1980s – De Beers controls as much as 80–90% of the world’s rough diamond supply, creating unprecedented market stability.

1967 – Major discoveries in Botswana eventually lead to the formation of Debswana, transforming Botswana into one of Africa’s greatest economic success stories.

1990s – Increasing production outside the De Beers system begins reducing the company’s market dominance.

2001 – De Beers introduces its “Supplier of Choice” strategy, shifting from stockpiling diamonds to demand-driven marketing.

2011 – Anglo American acquires full ownership of De Beers after purchasing the Oppenheimer family’s stake.

2018 – De Beers launches Lightbox Jewellery to enter the laboratory-grown diamond market, recognising changing consumer trends.

2025 – Lightbox is wound down as De Beers recommits its strategy to natural diamonds.

2026 – Anglo American enters negotiations to sell De Beers for approximately US$1 billion.

A New Beginning Rather Than the End

Although the proposed valuation represents a dramatic decline from De Beers’ former glory, the company still possesses some of the world’s most recognised diamond brands, valuable mining assets and decades of expertise.

More importantly, De Beers leaves behind a legacy that reshaped the global jewellery industry. It pioneered diamond marketing, built international confidence in natural diamonds and helped establish universal grading standards that continue to underpin the modern trade.

The challenge for new ownership will not be rebuilding history—but adapting that remarkable legacy to a new generation of consumers in a market where natural diamonds must increasingly differentiate themselves through rarity, provenance and enduring value.

WFDB Leadership Vote Signals a Turning Point for the Global Diamond Trade

 

The World Federation of Diamond Bourses (WFDB) is preparing for one of its most closely watched presidential elections in decades, with three prominent industry figures competing to lead the organisation at a time when the natural diamond sector faces unprecedented change.

Delegates will cast their votes during the World Diamond Congress in Singapore, where a new president will succeed Yoram Dvash after he completes the maximum two consecutive three-year terms.

While leadership contests have traditionally attracted little public attention, this year’s election has become a reflection of much larger issues confronting the international diamond industry.

A Federation at a Crossroads

For more than 80 years, the WFDB has represented the world’s diamond exchanges and promoted ethical trading standards, cooperation and confidence in the natural diamond market.

Today, however, the role of traditional diamond bourses has evolved significantly.

Digital trading platforms, changing supply chains, direct manufacturer-to-retailer relationships and the rapid growth of laboratory-grown diamonds have transformed the industry. Many market participants now question how the WFDB should adapt to remain relevant in a rapidly changing commercial landscape.

The next president will inherit an organisation that must redefine its purpose while maintaining unity among members from vastly different markets and business models.

Three Candidates, Three Perspectives

The election features candidates representing three of the world’s most influential diamond centres.

• Mehul Shah of India’s Bharat Diamond Bourse brings decades of experience within both the WFDB and the international natural diamond trade. His campaign focuses on strengthening existing institutions, preserving industry traditions and gradually introducing new leadership through experience and mentorship.
• Lin Qiang, President of the Shanghai Diamond Exchange, advocates greater international cooperation while seeking fresh strategies to stimulate global consumer demand for natural diamonds. His emphasis is on building consensus and maintaining stability across the federation.
• Ahmed Bin Sulayem, Chairman of the Dubai Diamond Exchange, represents a more modern and commercially aggressive approach. Having helped establish Dubai as one of the world’s fastest-growing diamond trading hubs, he has attracted support from younger industry members calling for structural reform and renewed relevance for the federation.

Rather than simply choosing between individuals, member exchanges are effectively deciding which strategic direction the WFDB should follow over the coming decade.

Experience Versus Modernisation

One of the defining themes of the campaign has been the balance between experience and innovation.

Supporters of established leadership argue that governing an international federation requires decades of industry knowledge, trusted relationships and an understanding of the complex political and commercial issues affecting the global diamond trade.

Others believe the organisation must modernise more rapidly, attracting younger leadership capable of responding to changing consumer behaviour, digital commerce and increased competition from alternative luxury products.

The debate mirrors similar discussions taking place throughout the jewellery industry, where many long-established organisations are reassessing their relevance in a rapidly evolving marketplace.

The Lab-Grown Diamond Challenge

Perhaps no issue better illustrates the industry’s changing landscape than laboratory-grown diamonds.

Natural diamonds remain the core focus of the WFDB, yet the commercial reality is that many member companies now operate in both natural and laboratory-grown sectors.

This creates a delicate balancing act.

Some industry leaders believe the federation should remain exclusively focused on protecting and promoting natural diamonds.

Others argue that ignoring the growing laboratory-grown sector risks reducing the organisation’s influence over a significant portion of today’s diamond market.

The differing views among the candidates highlight the broader debate taking place throughout the global jewellery industry.

Shifting Centres of Influence

The election also reflects changing geographical power within the diamond business.

India continues to dominate cutting and polishing, while China remains one of the world’s largest consumer markets despite softer demand in recent years.

Meanwhile, Dubai has rapidly emerged as a major international trading hub, attracting significant volumes of rough and polished diamonds through its strategic location, favourable business environment and expanding infrastructure.

These shifting trade flows have altered the traditional balance of influence once dominated by historic centres such as Antwerp, Tel Aviv and New York.

More Than a Presidential Election

Beyond selecting a new president, the World Diamond Congress will consider broader initiatives aimed at strengthening international cooperation among member exchanges.

Delegates are also expected to discuss expanding membership and improving collaboration as the industry responds to changing market conditions, evolving consumer expectations and ongoing economic uncertainty.

The outcome of the election will not determine the future of the diamond industry on its own. However, it will provide a clear indication of how the world’s leading diamond exchanges believe the sector should respond to one of the most significant periods of transformation in its history.

Whether the federation chooses continuity, reform or a balance between the two, the decision will help shape the direction of the natural diamond trade for years to come.

De Beers Sale Nears Final Chapter as Anglo American Moves to Exit Diamond Business

 

The long awaited sale of De Beers appears to be approaching its final stage, with Anglo American expected to complete the transaction before the middle of 2026 as the mining giant continues its strategic shift away from diamonds.

Speaking on 16 June at the Reuters NEXT Europe economic summit in London, De Beers CEO Al Cook indicated that the sale process could be concluded within “a few weeks, rather than a few months”, signalling that one of the most significant transitions in the modern diamond industry is moving closer to completion.

After more than a century as one of the most influential names in the global diamond trade, De Beers is entering a new era. Anglo American began reviewing its portfolio in 2023 as part of a broader strategy focused on commodities with stronger long term growth potential, including copper, iron ore and minerals linked to the global energy transition.

The shift comes after a challenging period for the diamond market. Between 2022 and 2025, De Beers experienced a substantial decline in financial performance, with sales falling from approximately US$6.6 billion in 2022 to around US$3.5 billion in the latest reporting period. Production also declined from approximately 35 million carats to 21.7 million carats.

Changing Consumer Demand Reshapes the Diamond Market

The decline in luxury spending in China, combined with the rapid growth of lab grown diamonds in the United States, has placed significant pressure on demand for natural diamonds.

The market has experienced three consecutive years of weaker demand, forcing the industry to reassess supply, pricing strategies and the long term role of natural diamonds in the luxury sector.

Despite these challenges, interest in acquiring De Beers remains strong. The company continues to attract potential buyers, including strategic investors, diamond producing nations and experienced industry figures.

Botswana, which already owns a 15 per cent stake in De Beers, has been exploring opportunities to increase its involvement alongside international partners. Diamonds remain central to Botswana’s economy, representing a major share of export earnings and a significant contributor to national GDP.

A greater ownership position could allow Botswana to capture more value from the diamond supply chain and increase its influence over the future direction of the global diamond industry.

Future Diamond Supply Could Support Prices

While the short term market remains challenging, potential buyers are also focused on the longer term fundamentals of diamonds, particularly the issue of supply scarcity.

The discovery of major new diamond deposits has slowed significantly. The Luele mine in Angola is regarded as one of the most important discoveries of the past two decades, while several established mines in Canada and southern Africa are expected to reduce production or close in the coming years.

As global production declines, the balance between supply and demand could begin to shift. A tighter supply environment may provide support for natural diamond prices over the medium to long term.

The sale of De Beers represents more than a corporate transaction. It marks the end of an era for one of the most recognised names in luxury and signals a new chapter for the global diamond industry, where ownership, supply control and changing consumer preferences will shape the future of natural diamonds.

Natural Diamonds at a Turning Point: De Beers Sale Signals a New Era for the Global Diamond Industry

 

The natural diamond industry is entering a defining period of transformation as one of the world’s most influential diamond companies, De Beers, moves closer to a change in ownership while the broader market shows early signs of recovery after several challenging years.

De Beers CEO Al Cook has indicated that a sale of the diamond giant could be completed within weeks rather than months, bringing to a close a two year process of negotiations. Speaking at the Reuters NEXT Europe conference in London, Cook said discussions have reached an advanced stage and that the company is closer to a sale than ever before.

Anglo American placed its 85% stake in De Beers on the market in May 2024 as part of a wider restructuring strategy following a prolonged downturn in diamond prices, weaker consumer demand, and the rapid growth of lab grown diamonds.

De Beers remains one of the most important names in the global diamond industry, with operations spanning Botswana, Namibia, Angola, South Africa, and Canada. The company has played a central role in shaping the natural diamond market for more than a century.

The potential buyers include diamond producing nations and strategic investors. Botswana, which already owns a 15% stake in De Beers, along with Namibia and Angola, have shown interest through various partnerships. These countries recognise the importance of diamonds to their economies and are looking to secure a stronger role in the future direction of the industry.

Cook highlighted that the current interest comes from groups with deep diamond knowledge, creating the opportunity for a strong public private partnership that could support the next chapter of De Beers.

Sources indicate that the number of potential buyers has narrowed from six groups in 2025 to two remaining consortia. These include diamond producing governments, former De Beers CEO Gareth Penny, investment groups, and international investors.

Natural Diamond Market Recovery Begins to Take Shape

While the industry has faced significant pressure since 2021, the market is showing signs of reaching a turning point.

The downturn was driven by several major structural changes. The rapid expansion of lab grown diamonds transformed consumer expectations, with improvements in CVD and HPHT technology allowing synthetic diamonds to become widely available at significantly lower prices.

This created pressure across the natural diamond pipeline as consumers became more focused on size and appearance rather than rarity and long term value.

At the same time, weaker luxury demand, particularly in China, reduced one of the industry’s most important growth markets. The slowdown affected miners, manufacturers, retailers, and diamond producing nations.

Botswana, the world’s largest diamond producer by value, experienced economic pressure as declining diamond revenues impacted national growth. The challenges highlighted the importance of diamonds not only as a luxury product but as a critical economic resource for producing countries.

A New Diamond Market Structure

The current recovery is unlikely to mirror previous diamond cycles. The industry is entering a new era where scarcity, provenance, quality, and consumer trust will become increasingly important.

Natural diamonds and lab grown diamonds are moving into different market positions. Lab grown diamonds compete primarily on affordability, while natural diamonds continue to represent rarity, geological history, and emotional value.

The potential sale of De Beers could become a major milestone in reshaping the future of the natural diamond sector. New ownership, combined with improving market fundamentals and a renewed focus on the uniqueness of natural diamonds, may help create the foundation for the next phase of the industry.

Production Rises, Prices Fall, and Technology Redefines Trust in Diamonds

 

De Beers Production Up, But the Market Signal Is Misleading

De Beers reported a 17% year-on-year increase in rough diamond production for Q1 2026, reaching 7.1 million carats. At face value, the figure suggests strengthening momentum. However, a deeper analysis reveals a far more measured reality.

The increase is primarily operational, not demand-driven. Output surged 88% quarter-on-quarter, largely due to a rebound from a deliberately reduced Q4 2025 production base. Key contributors included planned ore releases from the Gahcho Kué mine in Canada and higher underground volumes at Venetia in South Africa both outcomes of long-established mine plans rather than responses to improving market conditions.

This distinction is critical. Production growth tied to mine development cycles does not reflect rising consumer demand. Instead, it highlights the timing of extraction phases within capital-intensive, long-term mining programmes.

More telling is the divergence between volume and value. While production rose 17%, De Beers’ average realised prices declined by 19% over the same period. This inverse relationship underscores ongoing softness in the natural diamond market, where increased supply is not being met with corresponding demand.

Angola Expands Ambitions with Rio Tinto Joint Venture

In a strategic move to expand its diamond sector, Rio Tinto has entered into a joint venture with Angola’s state-owned Endiama to develop the Chiri project.

The new entity, Sociedade Mineira do Chiri, will be majority owned by Rio Tinto (75%), with the remaining stake held by Endiama. Located in Angola’s resource-rich eastern region, the project has already shown promising kimberlite indications following early-stage exploration.

While capital expenditure has yet to be allocated, the initiative reflects Angola’s broader strategy to increase diamond output and attract foreign investment. This comes at a time when global diamond prices remain under pressure, reinforcing the long-term nature of such investments rather than any short-term pricing optimism.

DiaDNA: A Technological Leap in Diamond Traceability

KP Sanghvi & Sons has introduced DiaDNA, a next-generation traceability platform that represents a significant advancement in diamond authentication.

Unlike traditional methods that rely on inscriptions, documentation, or external markers, DiaDNA analyses the diamond at an atomic level using advanced scanning and artificial intelligence. This process generates a unique structural “fingerprint” inherent to the stone itself immutable and impossible to replicate.

Each fingerprint is securely stored in a cloud-based system, allowing verification at any stage of the supply chain, from manufacturing through to retail. The technology enables:

• Independent, real-time authentication
• Enhanced provenance tracking
• Reduced reliance on fragmented paperwork
• Greater transparency for consumers and compliance teams

Fully integrated into KP Sanghvi’s Surat operations since 2024, DiaDNA signals a broader industry shift toward verifiable, data-driven provenance. As expectations around ethical sourcing and transparency continue to rise, such innovations are likely to become central to maintaining trust in natural diamonds.

---

Market Perspective

The Q1 2026 landscape presents a clear narrative: increased production does not equate to increased demand. While miners continue to execute long-term operational strategies, pricing pressures persist across the market.

At the same time, structural shifts are underway. Nations like Angola are positioning for future supply growth, while technological innovation exemplified by DiaDNA is redefining how diamonds are tracked, authenticated, and ultimately trusted.

For the trade, the message is precise: understanding the difference between operational supply growth and genuine market demand has never been more important.

Anglo flags third De Beers writedown as Teck merger looms

 

Anglo American is weighing a third writedown of De Beers in as many years as weak diamond prices persist and the miner advances asset sales ahead of its merger with Canada’s Teck Resources.

The century-old group said on Thursday it was reviewing the carrying value of its diamond business after average realized prices fell in 2025, warning the unit is likely to be lossmaking again.

The potential impairment comes as Anglo moves to finalize the sale of non-core assets, including De Beers. At the same time, the miner is preparing to merge with Teck in a transaction approved by shareholders and regulators late last year, creating Anglo Teck (official named confirmed).

The company booked a $2.9 billion impairment on De Beers in February last year, following a $1.6 billion writedown in 2024. Anglo, which owns 85% of the diamond company, offered few details on a sale process, saying only that it was “progressing.”

In a fourth-quarter production update, Anglo said diamond trading conditions “continued to be challenging” amid industry weakness, geopolitical tensions and tariff uncertainty. It said lower prices and market conditions could lead to an impairment when full-year results are released.

Diamond prices have come under pressure from weaker consumer demand in China and competition from cheaper, lab-grown stones. De Beers’ average realized price fell 7% to $142 per carat in 2025, driven by a 12% drop in the average rough price index.

Anglo said the decline was exacerbated by selling inventory below cost, largely lower-value goods. Adjusted for that mix, the equivalent price index reduction would have been 25% year on year, suggesting some underlying resilience in the market.

De Beers sold 5.9 million carats in the fourth quarter, up from 4.6 million a year earlier, lifting revenue to $571m from $543m. Even so, Anglo said it was undertaking an impairment review that could result in another writedown.

Exit hurdles
The prolonged slump complicates Anglo’s efforts to exit De Beers. Chief executive Duncan Wanblad said only that the sale was moving forward. A consortium led by former De Beers managing director Gareth Penny is seen as a frontrunner, though Botswana, which owns 15% of the company, has said it wants to take control.

Namibia has also expressed interest, and former chief executives Bruce Cleaver and Penny have been mentioned as potential buyers.

The De Beers sale forms part of a restructuring unveiled in 2024. Anglo demerged its platinum arm, Amplats (now Valterra), in June 2025, while the planned sale of its Australian metallurgical coal mines stalled after Peabody Energy (NYSE: BTU) walked away following a fire at Moranbah North.

Wanblad said on Thursday that the formal sale process for steelmaking coal was “progressing well,” without naming alternative buyers or addressing potential compensation from the US firm.

Copper reality check
Copper remains central to the Anglo-Teck investment case, but near-term output expectations have softened. Anglo cut its 2026 copper guidance to 700,000 to 760,000 tonnes from 760,000 to 820,000 tonnes, citing lower grades at several operations.

It also trimmed 2027 guidance to 750,000 to 810,000 tonnes, including at Collahuasi in Chile, which Anglo and Teck plan to integrate with Teck’s neighbouring Quebrada Blanca mine. For the longer term, the group added new guidance for 2028 of 790,000 to 850,000 tonnes.

A 15-km (9.3-mile) conveyor would be built to feed Collahuasi’s high-quality ore into QB’s new processing plants. (Click on map to enlarge)
Copper production in 2025 was 695,000 tonnes, roughly flat year on year and at the lower end of guidance. Goldman Sachs said output missed its estimate by 5%, with Anglo’s Quellaveco mine in Peru falling short by 10% on lower-than-expected grades. Collahuasi’s underperformance was already known, while Los Bronces in Chile ended the year strongly.

Adjusting for Collahuasi, the underlying miss narrows to about 2%, which Goldman said better reflects what the market had already priced in.

A sharp rise in copper prices in recent months has renewed interest in the metal and helped spur merger talks between rivals, including the once again abandoned merger between Rio Tinto (ASX, LON: RIO) and Glencore (LON: GLEN).

With ageing mines delivering lower grades and new projects costly and slow to develop, copper dealmaking has become more attractive as supply constraints tighten across the sector.
