De Beers Collapse Means Lab Diamond Prices Stay Low: Canada 2026
De Beers lost $511 million in 2025. Anglo American has written it down $6.8 billion over three years and still cannot find a buyer. The forces that destroyed their business model are the same ones keeping lab diamond prices at historic lows for Canadian buyers today.
The question most diamond buyers have been asking for three years is simple: will prices recover? The answer, as of 2026, is almost certainly no. And the clearest proof is not a forecast. It is a 137-year-old company that bet everything on a recovery and lost.
De Beers spent decades controlling global diamond supply. When lab-grown diamonds began taking market share, it launched Lightbox, spending $90 million on a production facility designed to position lab diamonds as cheap fashion accessories unfit for romance. Buyers ignored the framing. Lightbox shut down in May 2025. Lab diamonds now account for over 45% of US engagement ring sales.
For Canadian buyers, this matters not because of the corporate story but because of what it confirms about pricing. This guide explains why prices are structurally low, what to look for before buying anywhere, and how to protect yourself from paying legacy margins on today's wholesale prices.
Why Prices Are Not Coming Back
Lab diamond prices fell because global CVD manufacturing capacity expanded more than 300% between 2020 and 2023, driven by producers in China and India operating at industrial scale. This is not a temporary oversupply that corrects when one company adjusts production. The knowledge, equipment, and infrastructure exist across hundreds of independent manufacturers. No single entity controls it.
Edahn Golan Diamond Research estimates the annual rate of wholesale price decline decelerated to high single digits entering 2026, down from 26% in 2024. Deceleration is not reversal. The market is finding a floor at historically low levels, not climbing back toward 2020 pricing.
"Lab-grown diamonds are becoming an accessible, everyday luxury, while natural diamonds are repositioning as exclusive symbols of enduring value."
Where the Savings Actually Went
The 74% wholesale price collapse did not automatically reach retail buyers. Edahn Golan documented this precisely: US specialty jewelers grew gross margins on lab diamonds from 48.9% in 2020 to approximately 74% by 2025. Wholesale prices fell. Retail prices at legacy retailers did not fall proportionally. The gap went to margin.
Canadian buyers face a second layer on top of this. Most major lab diamond retailers are US-based and price in USD. A Canadian buyer pays the legacy retail margin plus currency conversion. A direct-to-consumer retailer pricing in CAD, sourcing from the same wholesale market, reflects the actual price collapse rather than absorbing it.
Three Questions to Ask Before Buying Anywhere
A full report includes all four Cs, a clarity plot, and a report number laser-inscribed on the stone's girdle. Verify it at verify.igi.org before purchase. Many retailers advertise "IGI certified" while delivering card certificates that omit most of this detail.
In 2025, 85.9% of lab diamonds sold were colorless and 35.3% were VVS clarity, per BriteCo's November 2025 data. Colorless and VS+ are the market standard now, not premiums. Accepting G color or SI clarity in 2026 is buying below baseline without a meaningful budget benefit.
Find one DTC retailer pricing in the same currency before committing. The difference between a DTC price and a legacy retailer price for identical specifications is the margin you are paying above the wholesale-reflective price. This takes ten minutes and is the most useful thing a buyer can do.

Frequently Asked Questions
No. Global CVD manufacturing capacity expanded more than 300% since 2020 and Chinese and Indian producers scale independently of any single company. De Beers' attempt to contain prices through Lightbox failed. Edahn Golan estimates the rate of decline has decelerated to high single digits in 2026, meaning prices are stabilizing at low levels, not recovering toward 2020.
Two factors. First, legacy US retailers grew gross margins on lab diamonds from 48.9% to 74% between 2020 and 2025, per Edahn Golan, by not passing wholesale savings to buyers. Second, Canadian buyers absorb currency conversion on top of that margin. A direct-to-consumer retailer pricing in CAD reflects the actual wholesale market price.
A full IGI grading report, not a card certificate. The full report includes all four Cs, a clarity plot, and a report number inscribed on the stone's girdle verifiable at verify.igi.org. Minimum specifications: E-F color, VS+ clarity, Very Good or Excellent cut for round stones. These are the market standard in 2026, not premiums.
Yes. The structural conditions driving prices down remain intact. De Beers' collapse removes the last major player with resources to attempt price stabilization. The direct-to-consumer prices available to Canadian buyers in 2026 reflect the new market equilibrium and are structurally unlikely to reverse.
