Steep Rise in De Beers Rough Production

 

De Beers says rough diamond production increased by 17% in the first three months of 2026, to 7.1 million carats.

The increase was largely driven by the release of stockpiled ore at Gahcho Kue, in Canada, (up 163%) and higher underground volumes at Venetia in South Africa (up 53%).

The loss-making miner said, however, that trading conditions remained “challenged” due to ongoing industry, geopolitical and tariff headwinds.

Rough sales at the two sights held during the quarter saw revenue rise, year-on-year by almost 25% to $648 million, although average per carat prices fell 19% to $101.

Production guidance for 2026 remains unchanged at 21-26 million carats, the company said in its Production Report for the First Quarter of 2026, published on 28 April.  

Actual rough production was 24.7 million carats in 2024 and 21.7 million carats in 2025.

Botswana, which accounts for more than two thirds of all De Beers’ diamonds, saw production rise by 5% year-on-year during Q1 2026.

There was a 12% drop in Namibia, due to scheduled maintenance on two vessels at Debmarine Namibia and the of decommissioning two vessels.

There was 53% production rise in South Africa, largely due to increased processing of underground ore from Venetia, and a 163% increase in Canada due to the planned release of ore from a new area of Gahcho Kue.

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.

Diamond Debut for De Beers and Sotheby's Collaboration

 

The sale of the Jwaneng 28.88 diamond later this month marks the start of a collaboration between De Beers and Sotheby’s.

Together they aim to “present exceptional diamonds as works of art,” although no details on the terms or scope of the agreement have been made public.

The collaboration centers on joint marketing and storytelling, going beyond a standard consignment, in which the miner selects an auction house.

Both companies co-create a branded narrative – “earth to art” – to promote across their channels

The flawless D-color unmounted Jwaneng 28.88 – cut from a 114.83-carat rough recovered at Botswana’s Jwaneng mine (Debswana, De Beers’ 50-50 government venture) -leads the auction at Sotheby’s Magnificent Jewels & Jadeite sale in Hong Kong on 23 April.

It carries an estimate of HKD 17 million to HKD 22 million (USD 2.2 million to USD 2.8 million).

Other De Beers diamonds from Jwaneng will be offered at the same sale, including a solitaire ring and a pair of diamond earrings.

De Beers Group extends Desert diamonds into bridal with a new palette of lighter hues

 

De Beers Group today announces the next chapter of Desert diamonds: an extension of the industry-wide beacon concept into the bridal market, bringing a fresh interpretation of natural diamond engagement and wedding jewellery through a refined spectrum of warm, nature-made hues that reflect enduring love and personal expression.

First launched to consumers in 2025 as De Beers Group’s first new beacon in over a decade, Desert diamonds is supported by De Beers’ largest category marketing investment in more than ten years. Developed to galvanise the industry around a central idea, Desert diamonds celebrates the wild, natural origin of natural diamonds and the distinctive spectrum of tones that occur in nature — from warm whites to champagne hues — offering consumers a compelling, authentic story of individuality and connection.

A natural evolution into bridal

The new bridal-focused chapter builds on the strong cultural momentum Desert diamonds has generated since launch, as warmer-toned diamonds become increasingly visible in popular culture and are worn by high‑profile figures across fashion, music and entertainment – including Bad Bunny, Doja Cat and Teyana Taylor.

This cultural momentum has also been reflected in some of the world’s most talked‑about bridal moments. Taylor Swift’s engagement ring, crafted by Kindred Lubeck, widely noted for its warm, candlelight diamond tone, has become a powerful cultural reference point for consumers.

This cultural interest has also translated into retail impact. Independent retailers who were involved in the first Desert diamonds campaign across the US reported increased foot traffic during the campaign’s initial run in 2025 and a rise in bridal‑led enquiries, with consumers increasingly interested in how these naturally warm tones could be applied to life’s most meaningful milestones — particularly engagement and wedding jewellery.

A lighter desert palette for modern bridal

Launching 13 April 2026 across the United States, Desert diamonds bridal is designed to meet growing interest in a more versatile, accessible spectrum of diamond colours — a softer, lighter desert palette that testing indicates resonates strongly with bridal audiences seeking authenticity and individuality in their choice of engagement and wedding jewellery.

The campaign will feature design archetypes including solitaire rings, three-stone rings and diamond bands and eternity-style pieces, created to highlight the natural variation and character of each stone.

An industry‑wide programme to inspire renewed desire

As with previous De Beers beacons — from the diamond bands to the tennis bracelet — Desert diamonds is designed as an industry‑wide programme with the goal of celebrating natural diamonds and reigniting consumer desire. De Beers has collaborated with over 60 designers across the industry to develop collections that interpret the desert‑inspired palette across both engagement and bridal jewellery, including Kindred Lubeck, designer of Taylor Swift’s engagement ring, with pieces available for future brides and couples to purchase.

Sandrine Conseiller, CEO of De Beers Brands & Diamond Desirability, said: “The success of Desert diamonds has reaffirmed something we’ve long believed: today’s consumers are drawn to what is real, rare and deeply personal. By celebrating the naturally occurring beauty and individuality of natural diamonds, the campaign struck a chord culturally and at retail, inviting a new generation to reconnect with the story behind their diamond.

Extending Desert diamonds into bridal is a natural next step. When people choose an engagement or wedding ring, they’re looking for authenticity — a symbol that feels true to who they are and the love they share. With this lighter, desert‑inspired palette, we’re offering couples a diamond that reflects their own story: shaped by nature, rich in character, and unlike anything else.”

De Beers’ Desert diamonds bridal campaign is supported by an integrated marketing programme across digital, social, outdoor and experiential channels. Through evocative storytelling, the campaign brings the Desert diamonds story into the context of love and commitment, drawing parallels between the individuality of each diamond and the unique journeys of the people who wear them. The creative spotlights how every diamond is shaped by nature and time, inviting brides to celebrate a commitment that is truly their own.

De Beers Reports $511 Million Loss as Global Diamond Crisis Deepens

 

The global diamond industry is facing its most severe downturn in decades, with De Beers posting a staggering $511 million EBITDA loss for 2025 — a dramatic collapse that underscores mounting structural pressures across the natural diamond market.

Despite generating approximately $3.5 billion in revenue, profitability deteriorated sharply, highlighting a widening disconnect between stable turnover and collapsing margins. The downturn reflects a perfect storm of falling realised prices, swelling inventories, rising operational costs and intensifying competition from laboratory-grown alternatives.

This historic loss signals more than a cyclical slowdown — it marks a structural turning point for the global diamond sector.

---

Why Did De Beers Record a $511 Million Loss?

The scale of the financial decline is unprecedented. The company’s EBITDA performance deteriorated nearly 2,000% year-on-year, shifting from manageable losses into industry-defining deficits.

Key Drivers Behind the Collapse:

• Lower realised rough diamond prices
• Inventory accumulation throughout the midstream
• Production cuts impacting fixed-cost absorption
• Asset impairment charges reflecting weaker long-term pricing assumptions

While revenues remained broadly stable, margins compressed dramatically — revealing that demand weakness is affecting pricing power rather than transaction volume alone.

---

Production Cut by 12% as Supply Is Calibrated

In response to deteriorating market conditions, rough diamond production was reduced by 12% to 21.7 million carats in 2025.

Unlike gold or oil markets where production cuts can rapidly rebalance supply, the diamond sector operates through a complex value chain involving mining, cutting, polishing and retail distribution. Inventory build-ups in 2025 forced disciplined output reductions designed to:

• Preserve cash flow
• Prevent further price collapse
• Protect long-term reserve value
• Stabilise global supply

However, elevated stockpiles remain a major overhang for 2026.

---

Lab-Grown Diamonds Accelerate Structural Disruption

Laboratory-grown diamonds continue gaining market share, particularly in engagement rings — historically the most valuable segment of natural diamond demand.

These synthetics are chemically identical but typically sell for 60–80% less than natural stones.

Competitive Advantages of Lab-Grown Diamonds:

• Lower retail prices
• Ethical and environmental positioning
• Consistent quality
• Rapid scalable production

Millennial and Gen Z buyers are demonstrating increased price sensitivity and different value priorities compared with previous generations — a demographic shift that is reshaping long-term demand dynamics.

---

China’s Luxury Slowdown Hits Diamond Demand

China, once a powerful growth engine for premium diamond jewellery, is experiencing reduced luxury consumption.

Key contributing factors include:

• Slower GDP growth
• Property market weakness
• Lower consumer confidence
• Currency sensitivity to imports

With Chinese buyers representing a significant share of high-end global diamond demand, the slowdown is having a disproportionate impact on producers.

---

US Tariffs Disrupt Indian Diamond Processing Hub

Trade policy has compounded the crisis. India processes roughly 80% of the world’s rough diamonds, and new US tariffs on Indian polished stones have created additional cost pressures and uncertainty.

The impact includes:

• Higher landed costs for US-bound diamonds
• Supply chain bottlenecks
• Planning uncertainty
• Competitive distortions

Even if tariff relief emerges later in 2026, industry participants remain cautious about near-term recovery.

---

Anglo American Takes $2.3 Billion Impairment

Parent company Anglo American recognised a $2.3 billion impairment related to its diamond division, reflecting revised long-term price expectations.

This writedown signals a structural reassessment of the sector rather than a temporary cyclical dip.

---

African Economies Feel the Pressure

Diamond-producing nations such as Botswana face heightened economic vulnerability. Diamond revenues contribute substantially to:

• Government income
• Foreign exchange earnings
• Employment
• GDP

Production discipline across Southern Africa reflects both market necessity and economic sensitivity.

---

What Happens Next? Recovery Scenarios for 2026–2028

Industry forecasts suggest cautious optimisation in 2026, with gradual recovery potentially emerging through 2027–2028.

Key variables include:

• Inventory normalisation
• Stabilisation of Chinese demand
• Trade policy resolution
• Lab-grown market share plateau

However, structural competition from synthetic diamonds is likely permanent, meaning natural diamond producers must reposition strategically.

---

What This Crisis Reveals About Luxury Commodity Markets

The diamond downturn highlights broader lessons for luxury commodities:

• High income elasticity creates sharp downturn risk
• Supply chains concentrated in single regions amplify vulnerability
• Technological disruption can permanently reshape pricing structures
• Inventory cycles in opaque markets create extended recovery timelines

Unlike transparent commodities such as gold, diamond pricing lacks a centralised exchange — increasing volatility during stress periods.

---

Investment Perspective

For long-term investors, sector distress can present contrarian opportunities — but risks remain elevated.

Favourable characteristics may include:

• Low-cost producers
• High-grade deposits
• Strong balance sheets
• Vertical integration

Nevertheless, structural shifts in consumer preference require careful risk-adjusted evaluation.

De Beers Confirms 2026 Sight Dates and Cuts Rough Diamond Prices as Global Market Pressures Intensify

 

De Beers has released its 2026 sight schedule, confirming it will maintain its traditional 10 rough diamond sales over the 12-month period, providing a degree of operational continuity amid prolonged uncertainty across the global diamond industry.

The miner sells approximately 90% of its rough diamond output to approved sightholders, who commit to purchasing set volumes of rough diamonds in exchange for consistent and predictable supply. In line with this strategy, De Beers has confirmed it will extend its current sightholder agreement through 30 June 2026, ensuring stability within its sight system during a challenging market environment.

The extended contract continues to regulate De Beers’ rough diamond sales, which are sourced from its wholly owned and joint-venture mining operations in Botswana, Namibia and South Africa. Sales will continue to be conducted in these producing countries.

In a minor operational adjustment, De Beers announced that the April and September 2026 sights will be shortened to four days, compared with the traditional five-day format.

De Beers 2026 Sight Dates

• Sight 1: 19–23 January
• Sight 2: 23–27 February
• Sight 3: 23–27 March
• Sight 4: 27–30 April
• Sight 5: 25–29 May
• Sight 6: 6–10 July
• Sight 7: 17–21 August
• Sight 8: 22–25 September
• Sight 9: 26–30 October
• Sight 10: 30 November–4 December

De Beers Cuts Rough Diamond Prices Amid Weak Demand

Alongside the announcement of its 2026 sight calendar, De Beers has reportedly cut rough diamond prices, reflecting mounting pressure from weak demand, surging lab-grown diamond supply and ongoing trade disruptions.

The January reduction marked the company’s first official price cut since December 2024, following months of quietly offering discounts while maintaining official list prices above prevailing market levels. At the first regular sight of the year, De Beers implemented price reductions on rough stones larger than three-quarters of a carat, according to industry sources.

The exact scale of the price cuts remains unclear, as De Beers has adjusted its billing structure and altered the composition of its diamond boxes, making direct comparisons difficult. Under the sight system, De Beers sets prices and indicates expected purchase volumes for sightholders, a structure that continues to give the miner significant influence over the rough diamond market, despite buyers retaining the technical right to refuse goods.

Industry Downturn and Structural Challenges

The global diamond industry is experiencing one of its deepest downturns in decades, with demand and prices for natural diamonds declining sharply from 2023 through 2025. Miners have been forced to scale back production and reassess long-term strategies as market conditions deteriorate.

A major structural challenge has been the rapid rise of lab-grown diamonds, whose prices have collapsed in recent years. This has enabled lab-grown stones to capture increasing market share, particularly in the bridal jewellery segment, undercutting natural diamonds across key consumer categories.

China, once a vital growth engine for diamond jewellery, has become a significant drag on demand due to a slowing economy and declining marriage rates. At the same time, geopolitical pressures, including tighter sanctions on Russian diamonds, ongoing tariff threats and global trade frictions, continue to disrupt the diamond supply chain.

Trade Tensions Add Pressure to India’s Diamond Sector

Further uncertainty has emerged from US–India trade tensions, which have weighed heavily on India’s diamond industry. Under President Trump, US tariffs on a range of Indian imports — including gems and jewellery — were raised to as high as 50%, creating additional headwinds for global diamond flows.

The impact has been particularly acute given India’s central role in the industry. The country cuts and polishes around 90% of the world’s diamonds by volume, while the United States remains its largest export market, accounting for approximately one-third to nearly half of India’s diamond and jewellery exports.

Namibia’s Diamond Output Hit by Price Drops and Lab Growns

Namibia’s rough diamond production fell by 3.5 per cent year-on-year during Q3 2025, as prices fell, demand for lab growns increased and inventories grew.

The Bank of Namibia said in its quarterly bulletin that the country’s output was 442,000 carats, down by 15.3 per cent on the previous quarter, valued at N$ 2.41bn (USD 147.3m).

“The decrease stemmed from planned actions to lower production at Debmarine Namibia on the back of a combination of downside pressures, including the falling price due to rising demand for lab-grown diamonds and high inventory levels.”

It said rough diamond revenue for Q3 fell by 19 per cent year-on-year and 17.4 per cent compared with the previous quarter.

The bank noted “persistently soft consumer demand in key markets such as China and the United States” as well as oversupply of diamonds by some major producers.

Namibia’s diamond sector is a cornerstone of its economy, historically accounting for 7 to 10 per cent of its GDP and 30 per cent of export earnings. Around three quarters of diamonds are recovered from the seabed by Debmarine’s fleet of ships.

De Beers Launches “Desert Diamonds” – A Bold Campaign Celebrating the Uniqueness of Natural Diamonds

De Beers has unveiled its largest natural diamond campaign in over a decade, reaffirming the beauty, rarity, and authenticity of natural diamonds in an era where lab-grown stones are increasingly prevalent.

The new campaign, titled “Unlike Anything,” introduces Desert Diamonds — a collection inspired by the natural hues of the desert, showcasing warm, earthy tones that celebrate individuality and the timeless connection between nature and human emotion.

As mass-produced, lower-cost lab-grown diamonds continue to gain market share, De Beers’ message is clear: natural diamonds remain unmatched — each one a product of geological wonder, billions of years in the making, and entirely unique.

According to De Beers, research found that 90% of consumers expressed interest in purchasing a Desert Diamond as a distinctive expression of style and a symbol of connection with nature. The campaign positions these desert-inspired shades as markers of authenticity, highlighting how the nuances in colour reflect the natural beauty and individuality of each stone.

“With Desert Diamonds, the ancient sands of time meet today’s zeitgeist for authentic beauty,” said Sandrine Conseiller, CEO of De Beers Brands. “Natural diamonds are unique and rare – no two are the same. Their colours have been forged by nature and perfected over billions of years.”

The growing appreciation for warmer diamond tones has also been influenced by high-profile figures such as Taylor Swift, whose engagement ring features a vintage old mine-cut diamond with a soft “candlelight glow,” as well as Kim Kardashian and Doja Cat, both of whom have embraced the desert-diamond aesthetic.

Industry analysts note that De Beers’ strategy goes beyond aesthetics. Chandler Mount, founder of Affluent Consumer Research Company, commented:

“Desert Diamonds mark a shift from diamonds as objects to diamonds as identity. De Beers isn’t just selling colour — they’re selling character. This is white space strategy executed with emotional intelligence.”

For the DCLA (Diamond Certification Laboratory of Australia), which upholds the highest standards in natural diamond grading and certification, De Beers’ campaign reinforces a vital message: authentic natural diamonds remain irreplaceable — not only for their enduring beauty, but for the story each stone carries within it.

De Beers Shuts Down Lightbox Lab-Grown Diamond Brand to Refocus on Natural Diamonds

De Beers Group, the global diamond mining leader, has announced the closure of its lab-grown diamond (LGD) jewellery brand, Lightbox, marking a strategic pivot back to natural diamonds. The decision comes as part of the company’s broader Origins Strategy, launched in May 2024, to streamline operations and prioritise high-return business areas.

End of the Road for Lightbox

Launched in 2018, Lightbox was positioned to differentiate lab-grown diamonds from natural ones by offering transparent linear pricing at $800 per carat. However, the LGD market has undergone significant change. Wholesale prices for lab-grown diamonds in the jewellery sector have dropped by around 90%, pushing the market toward a cost-plus pricing model. This sharp decline in value has ultimately led De Beers to discontinue Lightbox.

In addition to market pressures, De Beers cited weakening demand and uncertainty around tariffs as contributing factors behind the closure. Discussions are currently under way for the sale of Lightbox’s assets, including its remaining inventory.

Reaffirming Commitment to Natural Diamonds

Al Cook, CEO of De Beers Group, emphasised that the decision to close Lightbox reflects the company’s long-term strategy to focus on natural diamonds, where brand heritage and enduring value remain strong.

“The persistently declining value of lab-grown diamonds in the jewellery market underscores the growing distinction between factory-made stones and natural diamonds,” Cook said.
“Global competition, especially from low-cost Chinese producers, and falling prices driven by US supermarkets, show that prices are likely to continue dropping. Lightbox played a role in clarifying the difference in value between lab-grown and natural diamonds.”

De Beers plans to reinvest resources from Lightbox into marketing campaigns and initiatives that enhance the global appeal of natural diamonds.

Support for Customers and Partners

As Lightbox operations wind down, De Beers will ensure a smooth transition for employees, suppliers, retail partners, and other stakeholders. Warranties and after-sales services for existing Lightbox purchases will continue to be honoured during the closure period.

Synthetic Diamonds to Power Innovation

While De Beers exits the LGD jewellery space, it remains invested in the future of synthetic diamonds in industrial and technological applications. Element Six, a De Beers subsidiary and former supplier to Lightbox, will continue developing lab-grown diamond solutions for sectors such as semiconductors, optics, and quantum technology.

Element Six will centralise its chemical vapour deposition (CVD) production in Oregon, USA, as part of its plan to strengthen global partnerships and fuel innovation across high-tech industries.

Auction House Pulls Fake Pink Diamond from Sale

A leading auction house was shocked to discover a pink diamond it planned to sell was actually a fake.

The gem was sent to the Institute of Diamonds – the De Beers diamond grading and verification division – ahead of the sale.

It was examined there and found to be a forgery, De Beers CEO Al Cook said in a LinkedIn post to his 42,500 followers.

“At first glance, the stone looks beautiful. It even has an inscription on the side which claims its a diamond,” he said.

But a combination of experts and sophisticated detection machines confirmed the stone was not actually diamond.

“As soon as our team looked at the stone, they suspected it was a fake,” said Cook in a follow-up to his original post.

“The certification inscription on the side had led the auction house to believe it was real.”

He also said: “Our team was quite excited to see this extraordinary stone and actually very sad when it turned out to be a fake.

“Luckily the fraud was stopped before an auction customer paid a vast sum of money!”

Cook didn’t provide further details, and De Beers declined to elaborate.

In his original post Cook said: “Henry Smith from our Institute of Diamonds confirmed that this pink stone was a forgery. ‘It had even been lasered with a fake inscription’.

“Henry explained that the auction house was shocked, but ‘cases like this emphasise the critical role of advanced detection technologies’.”

Cook also said in his post that De Beers was ramping up production of DiamondProof, the verification device aimed specifically at retailers that was showcased at JCK last year and which is now available in the US.

He said it can distinguish a natural diamond from a lab-grown or moissanite in a few seconds.
