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.
