De Beers Drops Prices to Near Market Rate
On Monday, 7 July 2026, De Beers made some of the deepest ever cuts to its official diamond prices. The move potentially ends the company's years-long effort to hold prices well above the market rate, according to Bloomberg via Mining Weekly.
The cuts covered nearly all categories of diamonds De Beers sells. People familiar with the situation confirmed the scale of the reductions. They asked not to be named discussing private information. A spokesperson for the company declined to comment.
We at iCharles are tracking this story as it develops — the details below reflect what sources have confirmed so far.
How Far Above Market Had De Beers Been?
De Beers' official prices had been between 5% and 50% higher than the secondary market, depending on the stone category. The secondary market is where traders, cutters, and polishers buy and sell diamonds among themselves.
After Monday's cuts, buyers said pricing is now much closer to that secondary market level.
| Measure | Before July 2026 Cuts | After July 2026 Cuts |
|---|---|---|
| Premium over secondary market | 5%–50% above, by category | Much closer to market rate |
| Per-category breakdown | Not disclosed (one-line invoicing) | Not disclosed |
Why Did De Beers Avoid Cutting Prices for So Long?
De Beers has outsize influence on the global diamond market. An official price cut can drag down sentiment across the whole industry. That is why the company avoided them.

Instead, De Beers ran secret sales of discounted stones. It kept official prices high at the same time. That approach held for years — until Monday.
What Caused the Industry Crisis?
Two forces drove one of the industry's worst and most prolonged crises, as reported by The Edge Malaysia:
- A pullback in Chinese luxury spending, which cut demand for natural diamonds.
- The rising popularity of synthetic stones — lab-grown diamonds that compete directly with mined ones.
On top of those pressures, Angola sold a record amount of stones at prevailing market levels. That undercut De Beers' price-holding strategy. US tariffs and the Middle East conflict added further pain.
What Is a Sightholder?
A sightholder is one of De Beers' handpicked, approved diamond buyers. This select group gets access to De Beers stones at set sales events.
Earlier in 2026, De Beers told its customers their number was being cut — from about 70 sightholders down to between 45 and 50. July's sale is the first under the new contract that followed that reduction. De Beers sees the smaller group as key to sending more diamonds to its strongest customers.
Why Is the Exact Scale of Cuts Hard to Measure?
De Beers introduced one-line invoicing earlier in 2026. Instead of pricing each individual box of diamonds, it now issues a single total invoice. That makes per-category cuts hard to calculate.
The company also changed the mix of diamonds in some boxes. That makes direct comparisons with past sales difficult, according to people familiar with the situation.
What Structural Changes Did De Beers Make to Its Sales Process?
Beyond the price cuts and the smaller buyer list, De Beers made two notable changes to how it sells:
- One-line invoicing — a single total per sale, not a per-box price list, introduced earlier in 2026.
- Revised box assortments — the mix of stones in some boxes was changed, making like-for-like comparisons harder.
Both changes reduce how much outside observers can track price movements from sale to sale. This kind of structural shift in a legacy commodity market is worth watching alongside broader industrial disruption — including the rise of autonomous government AI and AI-built enterprise tools that are reshaping how industries handle data and pricing transparency.
What Pressures Pushed De Beers to Act Now?
Several forces came together at once:
- Angola sold a record amount of diamonds at prevailing market prices.
- US tariffs added cost pressure across the supply chain.
- The Middle East conflict created further market disruption.
- De Beers cut its sightholder list, making July the first sale under a new commercial structure.
The July 2026 sale was the first moment where new buyer contracts, accumulated market pressure, and a prolonged pricing gap all landed at the same time.
De Beers is a unit of Anglo American plc. Its pricing decisions carry weight far beyond its own sales, given its historically dominant position in the global diamond supply chain. Shifts of this scale in legacy industries mirror the kind of structural change seen when a Microsoft AI unit reshapes an entire technology sector.
Going forward, De Beers will operate with a core purchasing group of between 45 and 50 buyers — down from roughly 70 — under the new sightholder contract.
