Namibia Rough Diamond Production Stays Stable in Windhoek
De Beers Namibia navigates shifting rough diamond market conditions amid global output changes

Namibia rough diamond production held firm at 500 000 carats during the third quarter of 2026, a rare pocket of consistency in an otherwise turbulent global output landscape.

 

While De Beers recorded an 11% drop in worldwide rough diamond production to 6.8 million carats over the same period, Namibia stood apart - a track record consistent with the country's recent history of relative resilience.

 

Planned maintenance at Botswana's Orapa Mine and a strategic wind-down at Venetia in South Africa were the primary drivers behind the global shortfall.

 

Botswana's output fell to 4.8 million carats, while South Africa slid to 400 000 carats as Venetia scaled back ahead of a scheduled two-year operational pause that is set to stretch into early 2027.

 

The Venetia slowdown marks one of the more consequential production shifts De Beers has undertaken in the Southern African region in recent years.

 

In Canada, output climbed to 1.1 million carats after higher-grade ore moved through the Gahcho Kué Mine, adding a bright note to an otherwise subdued global picture.

 

De Beers also assumed full ownership of Gahcho Kué following the enforcement of security over a joint venture partner's 49% stake, meaning the miner will now report 100% of that operation's production - a shift that inflates attributed output without adding new diamonds to global supply.

 

That structural change pushed De Beers' 2026 production guidance up to between 25 million and 28 million carats, from a prior range of 21 million to 26 million carats.

 

Unit cost expectations were also revised downward, from roughly US$80 per carat to approximately US$70 - a meaningful efficiency signal in a cost-conscious market environment.

 

On the trading side, the rough diamond market showed cautious signs of stabilisation, buoyed by firmer consumer demand out of the United States and India.

 

Yet the threat posed by laboratory-grown diamonds persisted, continuing to erode demand for lower-value natural stones, particularly in price-sensitive segments of the market.

 

Third-quarter rough diamond sales reached 9.8 million carats across two sales cycles, generating approximately US$731 million in consolidated revenue - a notable improvement on the US$700 million recorded in the same quarter of 2025, when volumes stood at a considerably lower 5.7 million carats.

 

Despite the revenue uptick, the year-to-date average realised price fell 37% to around US$97 per carat, reflecting both a declining price index and a shift in the composition of diamonds sold.

 

For Namibia, whose diamond sector has historically relied on both onshore Namdeb operations and offshore Debmarine vessels, quarterly output stability carries outsize economic significance.

 

De Beers Namibia confirmed it would continue monitoring rough diamond trading conditions and adjust production levels to reflect prevailing demand - a posture that signals measured caution rather than retreat.

    The joint venture partner's stake being enforced like that. Would love to know the full story behind that.

    Namdeb onshore plus Debmarine offshore is a really interesting dual model. Glad both seem stable for now.

    Measured caution rather than retreat. That is a very diplomatic way to say they are nervous about what comes next.

    De Beers adjusting guidance upward because of an accounting change rather than actual new production. Important distinction.

    731 million in revenue sounds good until you remember the price index dropped 37 percent. Mixed signals everywhere.

    Offshore diamond mining off the Namibian coast is something most people have never heard of. Worth looking into if you haven't.

    Cost per carat dropping from 80 to 70 dollars is actually meaningful. Shows they are tightening up operations properly.

    Venetia scaling back into 2027 is going to hurt South African output badly. 400 000 carats is already quite low.

    The Orapa maintenance timing always seems to come at the worst possible moment for global supply.

    Lab grown diamonds are cheap and people are buying them. Natural diamond producers better figure out a real answer soon.

    Good to see Namibia stable. We cannot afford another down quarter after last year.

    So revenue went up but price per carat went down 37 percent. They just sold a lot more stones. That is not the same as recovery.

    Canada quietly at 1.1 million carats with higher grade ore. Gahcho Kue is a serious mine.

    97 dollars per carat average is painfully low. I remember when these numbers looked very different.

    US and India demand picking up is actually encouraging. Was worried the market was just going to keep sliding.

    Debmarine vessels offshore are incredible operations honestly. People dont realise how much of our economy sits on those ships.

    De Beers taking full control of Gahcho Kue and then counting 100% of production. Clever way to make your numbers look better without actually producing more diamonds.

    Venetia shutting down for two years is huge. A lot of families in Limpopo depend on that mine.

    Lab grown diamonds are going to keep eating into the lower end. This is not going away.

    That drop from 5.7 million to... Wait no they sold more carats but the price per carat collapsed. That 37% price drop is the real story here.

    500 000 carats and holding. Namibia quietly doing its thing while everyone else struggles.
