Diamond Detection Keeps Advancing, And DCLA Has used the Technology for Decades

 

The technology used to identify laboratory-grown diamonds continues to advance, with De Beers Group announcing its next-generation SynthDetect™ 2 desktop diamond screening instrument.

For DCLA, however, the challenge of distinguishing natural diamonds from laboratory-grown diamonds is not new.

DCLA has been at the forefront of diamond detection and disclosure for more than two decades, recognising well before laboratory-grown diamonds became a mainstream commercial product that advances in diamond-growing technology would create a major challenge for the jewellery industry.

The next generation of diamond screening

De Beers says its new SynthDetect™ 2 builds on its earlier SynthDetect and SynthDetect XL instruments, introduced in 2017 and 2018.

According to De Beers, the new system is designed to make screening faster, more automated and easier to integrate into the day-to-day operations of diamond manufacturers, laboratories and retailers.

One of the most significant changes is speed. De Beers says a full tray scan that previously took approximately 30 minutes can now be completed in less than five minutes.

The instrument is designed to screen loose diamonds as well as a wide range of jewellery, including rings, earrings, necklaces, pendants, bracelets and bangles. De Beers states that SynthDetect 2 can screen diamonds from 0.001 to 10 carats in the D–J colour range.

The company says automated results, reporting and software updates are intended to further reduce operator input and improve screening efficiency.

De Beers currently lists SynthDetect 2 as being available from Q1 2027.

DCLA recognised the challenge long before it became mainstream

While new screening technology continues to improve, the underlying problem has been known for many years.

DCLA identified the potential impact of synthetic diamond technology on the Australian diamond industry as early as 2002, when the laboratory warned about advances in technologies such as CVD and HPHT and their potential to produce gem-quality laboratory-grown diamonds that could not be reliably distinguished from natural diamonds by ordinary visual examination.

That early recognition is particularly relevant today.

Laboratory-grown diamonds are real diamonds. They have essentially the same chemical composition and crystal structure as natural diamonds and can look virtually identical to the unaided eye.

The distinction is therefore not something that can reliably be established simply by looking at a stone.

DCLA has previously explained that sophisticated gemmological equipment is required to identify the characteristics associated with different diamond growth processes.

DCLA: Lab-Grown Diamonds — A Structural Disruption to the Traditional Diamond Industry

DCLA: What Is a Lab-Grown Diamond?

Detection has always been part of DCLA’s laboratory process

DCLA’s approach has never been based simply on whether a stone “tests as a diamond”.

That distinction is important.

A basic diamond tester can establish that a stone behaves like diamond. It does not necessarily establish whether that diamond was formed naturally or grown in a laboratory.

DCLA’s laboratory uses advanced analytical technology, combined with experienced gemmological examination, to investigate diamond origin, treatments and other characteristics.

DCLA’s published laboratory process states that diamonds are screened for known treatments and tested to establish whether they are natural or man-made, with grading conducted according to International Diamond Council standards.

The laboratory also uses technologies including DiamondView™ fluorescence imaging, which can reveal growth structures and fluorescence patterns that are not visible under normal lighting.

Why the technology race matters

The development of instruments such as SynthDetect 2 demonstrates how quickly diamond-screening technology is evolving alongside diamond-growing technology.

As laboratory-grown diamond production has become more sophisticated, identification technology has had to become more sophisticated as well.

This is not simply a question of identifying whether a stone is “real”.

A laboratory-grown diamond is diamond. The critical question is whether its origin has been correctly identified and disclosed.

That distinction becomes particularly important when diamonds are bought, sold, traded, insured, certified or resold.

DCLA has encountered cases where advanced testing has uncovered synthetic diamonds presented in circumstances where their identity or origin was in question.

In one case documented by DCLA, an HPHT-grown synthetic diamond had been fraudulently inscribed with a report number intended to correspond to a natural diamond. Advanced testing identified differences in the stone’s characteristics and growth origin.

DCLA: Synthetic Diamond Fraudulently Inscribed to Match Natural Diamond Report

More recently, DCLA has also highlighted the risk of certificate swapping, where a genuine certificate may be presented with a different diamond from the one originally examined.

DCLA: Consumer Alert — Certificate Swapping Fraud

Screening is not the same as certification

Modern screening instruments are becoming faster and more accessible to the trade, and that is an important development.

However, screening and independent laboratory certification perform different functions.

A screening instrument can help a business rapidly identify stones requiring further examination.

A professional laboratory can go further by independently examining and documenting the characteristics of the individual diamond.

At DCLA, every diamond submitted for certification is examined by accredited gemmologists in the Sydney laboratory, with advanced instrumentation used alongside traditional gemmological examination.

DCLA — Independent Diamond Certification Laboratory

DCLA’s philosophy has remained consistent

The equipment may change.

The technology may become faster.

The screening process may become increasingly automated.

But the fundamental principle remains the same:

Know what the diamond is.

DCLA has consistently advocated transparency, independent testing and accurate disclosure as laboratory-grown diamond technology has evolved.

From recognising the potential impact of synthetic diamonds more than two decades ago, to using advanced detection technology today, DCLA’s role has been to help the Australian jewellery industry and consumers understand what technology can — and cannot — tell them.

As diamond-growing technology continues to advance, diamond detection technology will continue to evolve with it.

For consumers and the trade, that makes independent verification more important than ever.

A diamond may look natural. A basic tester may say “diamond”. But when origin matters, sophisticated testing and independent documentation provide the evidence.

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.

De Beers Slashes Diamond Prices and Reshapes Its Elite Buyer Network

 

The global diamond industry may have reached a major turning point.

De Beers has implemented some of the largest official rough diamond price reductions in its modern history while simultaneously removing almost one-third of its exclusive group of authorised buyers. The move represents a dramatic shift in strategy after years of attempting to keep official prices well above prevailing market levels.

For the diamond trade, manufacturers and retailers, this is more than simply a pricing adjustment it is a clear acknowledgement that market forces can no longer be ignored.

Official Prices Finally Catch Up With Reality

For much of the past three years, De Beers resisted cutting its published rough diamond prices despite a sharp fall in global demand.

Instead, the company quietly sold selected goods through confidential discounted transactions while maintaining higher official prices to preserve confidence throughout the industry.

That approach has now come to an end.

During its July 2026 sales cycle, De Beers made sweeping reductions across nearly every category of rough diamonds. Industry sources indicate that some categories had previously been priced between 5% and 50% above equivalent goods trading in the secondary market.

The latest reductions bring De Beers’ official pricing much closer to actual market values.

Although the company has declined to comment publicly on the exact reductions, the changes are widely regarded as some of the deepest official price cuts ever made by the company.

Understanding the Sightholder System

To appreciate why these price cuts are so significant, it is important to understand how De Beers sells its diamonds.

Unlike many commodities, rough diamonds are not sold on open exchanges.

Instead, De Beers operates through its long-established Sightholder System, a carefully selected network of approved companies invited to purchase rough diamonds directly from the miner.

These companies attend ten scheduled “sights” each year.

At each sight, buyers are offered parcels or “boxes” of rough diamonds at fixed prices determined by De Beers. There is generally little or no room for negotiation. Buyers may accept or decline the allocation, but historically repeated refusals risked losing their coveted sightholder status.

For decades, this system allowed De Beers to exercise remarkable control over the supply of rough diamonds entering the global manufacturing pipeline.

By carefully managing both supply and pricing, the company was able to influence the broader diamond market more effectively than almost any other mining company.

Fewer Buyers, Greater Concentration

The July 2026 sight is also the first held under newly negotiated supply agreements.

Perhaps the biggest structural change is the reduction in De Beers’ exclusive buyer network.

The number of authorised sightholders has been reduced from around 70 companies to approximately 45–50.

The objective is straightforward.

De Beers wants a smaller group of financially stronger customers capable of purchasing larger volumes while maintaining long-term commitments to the business.

The company believes concentrating sales among its strongest clients should reduce the number of diamonds being immediately resold into secondary markets, where discounted trading has undermined official pricing for several years.

In theory, fewer buyers should allow De Beers to exercise tighter control over the distribution of rough diamonds.

However, the strategy also carries greater risk.

With fewer customers, De Beers becomes increasingly dependent upon the financial health of each remaining sightholder. Should several major buyers reduce purchases or encounter financial difficulties, there are fewer alternative customers available to absorb production.

Why Is De Beers Changing Strategy?

The decision reflects several years of mounting pressure across the global diamond industry.

China, once one of the world’s fastest-growing luxury jewellery markets, has experienced a significant slowdown in consumer spending. Demand for diamond jewellery has weakened substantially, removing one of the industry’s largest growth engines.

At the same time, laboratory-grown diamonds have become increasingly popular, particularly in the bridal jewellery sector, where consumers can purchase much larger stones at a fraction of the price of natural diamonds.

The market has also faced increased competition from additional rough diamond supply entering global markets from countries including Angola.

Adding further uncertainty have been ongoing geopolitical tensions, US trade tariffs and slowing global economic growth, all of which have reduced consumer confidence in luxury spending.

Together, these factors have produced one of the deepest and longest downturns the diamond industry has experienced in decades.

Less Transparency Than Before

Ironically, while prices have become more market-driven, pricing transparency has actually decreased.

Earlier this year De Beers introduced a new “one-line invoicing” system.

Rather than providing detailed prices for each category of rough diamonds within a parcel, buyers now receive a single combined total for the entire box.

At the same time, the company has altered the composition of many assortments.

These changes make it difficult for manufacturers and market analysts to determine exactly how much individual categories of diamonds have increased or decreased in value.

This reduced transparency makes independent price analysis significantly more challenging than under the previous system.

A Business Preparing for Sale

The pricing changes also arrive during a crucial period for parent company Anglo American.

Since May 2024, Anglo American has been working to divest De Beers as part of a broader restructuring programme following years of declining profitability.

Potential buyers continue to evaluate the world’s most famous diamond producer while the company attempts to stabilise earnings and restore confidence throughout the market.

Resetting prices closer to genuine market levels may ultimately make De Beers a more commercially attractive business by reducing the disconnect between official pricing and actual trading conditions.

What It Means for the Diamond Industry

De Beers’ latest decisions signal more than a temporary response to weak trading conditions.

They represent a recognition that the natural diamond market has fundamentally changed.

The company appears to be abandoning a long-standing strategy of defending premium pricing in favour of allowing market realities to shape official valuations.

Whether these changes successfully restore confidence remains to be seen.

For manufacturers, wholesalers and retailers, pricing that more accurately reflects real market conditions may improve margins and encourage renewed trading activity.

For consumers, however, the changes are unlikely to produce dramatic retail price reductions in the short term, as jewellery prices are influenced by manufacturing costs, branding, retail margins and consumer demand as much as the price of rough diamonds themselves.

What is clear is that De Beers has entered a new chapter one where flexibility, commercial realism and supply discipline are becoming more important than maintaining the appearance of price stability.

De Beers Slashes Number of Sightholders

 

De Beers has reportedly slashed the number of sightholders who can buy their goods by as much as a third, as it seeks to consolidate supply among a small core of stronger buyers.

The number of sightholders is understood to have been reduced from 69 to around 45, although De Beers has not confirmed numbers. Sightholders were informed by letter or phone call on Friday, 20 March.

It is the second biggest cut, in percentage terms, since sights were launched back in 1934. The number of De Beers sightholders peaked at around 350 in the 1970s.

It was halved in April 2001 as the company sought to prioritize value-driven buyers over sheer volume of sales.

De Beers warned current sightholders back in October 2024 that it would be terminating some of their supply agreements, by way of what it called an objective selection and allocation process.

Existing contracts, signed in 2021 and extended last year through June 30, 2026, end soon, paving the way for the new roster starting July 1.

The cutback suggests that the loss-making miner is repositioning itself for survival in a weaker market by creating a limited customer base that can reliably take volume in tough times.

Anglo American’s repeated De Beers write-downs (the latest by $2.3bn in February 2026) underscore the loss-making reality. De Beers CEO Al Cook emphasized “quality over quantity” in late 2024, aiming for deeper partnerships including polished diamond sales from Botswana-sourced stones.

De Beers last reduced the number of sightholders in January 2021, when it introduced new contracts dividing buyers into three categories – dealers, manufacturers and integrated retailers.

De Beers to Release “A Diamond Is Forever” Book Celebrating a Century of Natural Diamond Legacy

 

De Beers is set to release A Diamond Is Forever, a new luxury book exploring the evolution of the company’s natural diamond marketing and its profound influence on global culture, romance, and society. The book will be published next week by Assouline, a renowned publisher of high-end illustrated volumes.

Named after one of the most iconic advertising slogans in history, A Diamond Is Forever celebrates the cultural, artistic, and emotional legacy of natural diamonds — nature’s oldest treasure and one of humanity’s most enduring symbols of love and commitment.

De Beers is widely credited with transforming diamonds from an exclusive luxury reserved for society’s elite into a universal symbol used to mark life’s most important romantic milestones and personal achievements. Prior to the 1930s, diamond jewellery was exchanged discreetly within elite circles, with luxury houses maintaining strictly private client relationships. De Beers reshaped this narrative, positioning diamonds at the heart of modern romance.

In 1947, De Beers copywriter Frances Gerety coined the legendary phrase “A Diamond Is Forever,” embedding the gemstone into global consciousness as a lasting promise of love, endurance, and emotional significance. The slogan appeared across archival print advertising, magazine spreads, and celebrity endorsements, cementing the diamond’s place in popular culture.

The book also highlights De Beers’ historic collaborations with celebrated artists such as Pablo Picasso, Salvador Dalí, and Raoul Dufy, drawing parallels between the rarity of diamonds and the genius of fine art. These campaigns elevated diamonds beyond jewellery, reinforcing their artistic and cultural value while preserving a sense of exclusivity.

During the 1960s, Hollywood icons including Elizabeth Taylor and Marilyn Monroe further amplified the glamour of diamonds, while the company’s influential 1990s “Shadows” campaign — set to Karl Jenkins’ Palladio — captured the gemstone’s timeless, authentic, and eternal nature.

Over the past two decades, De Beers has periodically retired and revived the famed slogan, most recently reintroducing it in late 2023 as part of a refreshed “Seize the Day” campaign, originally launched in the 1990s.

According to the publisher, the story of diamonds is one of both transformation and continuity. In recent years, the narrative has expanded to include provenance, sustainability, and ethical stewardship, reinforcing the natural diamond as a symbol not only of beauty and permanence, but also of responsibility and conscience.

A Diamond Is Forever spans 240 pages and features 180 illustrations. Presented as a hardcover book housed in a luxury slipcase, it will retail for USD $195 and is scheduled for release on January 30.

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.
