How a global slump, lab-grown diamonds and the possible sale of De Beers are forcing Namibia to rethink one of the pillars of its economy
For more than a century, diamonds have been synonymous with Namibia’s prosperity.
They built Oranjemund from a windswept settlement into one of southern Africa’s most exclusive mining towns.
They financed roads, schools and hospitals, generated billions of Namibia dollars in export earnings and established Namibia as one of the world’s most respected producers of gem-quality diamonds. Few industries have shaped the country’s economy as profoundly.
Today, however, the sparkle has dimmed.
The global diamond industry is experiencing its deepest structural crisis in decades. Prices for natural diamonds have fallen sharply since their post-pandemic peak, demand in China has weakened, younger consumers are questioning traditional luxury purchases, and laboratory-grown diamonds, once dismissed as novelty products, have become a mainstream alternative.
At the same time, one of the world’s most iconic companies is itself in transition. Anglo American, the mining giant that owns 85% of De Beers, is pressing ahead with plans to sell the business as part of a broader restructuring after years of declining earnings and multi-billion-dollar write-downs.
Reports indicate that a consortium led by former De Beers chief executive Gareth Penny has emerged as the preferred bidder, with governments including Botswana, Namibia and Angola expressing interest in the company’s future.
For Namibia, these are not distant corporate developments. They raise fundamental questions about the future of one of the country’s most important economic sectors.
When the world’s luxury market sneezes
Namibia’s diamond industry has always depended on consumers thousands of kilometres away.
When engagement ring sales slow in New York, luxury spending weakens in Shanghai or jewellery retailers reduce inventories in Mumbai, the effects are eventually felt in Lüderitz, Oranjemund and along Namibia’s Atlantic coastline.
Diamonds remain one of Namibia’s most valuable exports and continue to contribute significantly to government revenue through taxes, royalties and dividends from the 50-50 joint venture between the Namibian Government and De Beers, Namdeb Holdings.
But when prices fall, the consequences ripple through the economy.
Mining companies cut production. Exploration budgets shrink. Contractors receive fewer orders. Capital projects are delayed.
Government revenues come under pressure, narrowing the fiscal space available for infrastructure, healthcare and education.
This is precisely the environment Namibia now faces.
The downturn has become severe enough that Anglo American has repeatedly written down the value of De Beers, while the group’s revenues from diamonds have fallen dramatically from their 2022 highs.
The company that changed the world
Few companies have influenced consumer behaviour as profoundly as De Beers.
Its famous slogan, “A Diamond is Forever,” transformed diamonds from luxury commodities into symbols of eternal love.
For decades, De Beers controlled as much as 80% of the global rough diamond trade, carefully managing supply to support prices and cultivating the idea that a diamond engagement ring was an essential expression of commitment.
Today, that model is under unprecedented pressure.
“The sale of De Beers has never been closer,” Chief executive Al Cook recently said, indicating that a transaction could happen “in weeks rather than months” as Anglo American completes its restructuring.
The irony is difficult to ignore.
The company that once defined the global diamond industry is itself searching for a new owner.
The rise of the laboratory diamond
The greatest disruption has not come from another mining company.
It has come from technology.
Laboratory-grown diamonds are chemically, physically and optically identical to natural diamonds. They are not imitations like cubic zirconia or moissanite.
They are genuine diamonds, created in laboratories over several weeks instead of beneath the Earth’s surface over billions of years.
The difference lies in cost.
Where natural diamonds remain scarce by definition, laboratory production can be expanded.
As manufacturing technology improved, prices collapsed.
A laboratory-grown diamond that once sold for close to the price of a natural stone can now cost as much as 70% to 90% less.
For younger consumers facing rising living costs, the value proposition is compelling.
An engagement ring that once required months of savings can now be purchased at a fraction of the price.
A tale of two markets
The emergence of laboratory-grown diamonds has fundamentally changed the industry’s narrative.
Natural diamonds are increasingly being positioned as rare luxury assets with geological histories spanning billions of years.
Lab-grown diamonds are marketed as affordable, modern and technologically advanced.
Neither proposition is necessarily wrong.
Paul Zimnisky, one of the world’s leading independent diamond analysts, has repeatedly argued that the natural diamond industry must stop competing with laboratory-grown diamonds on price and instead reinforce rarity, provenance and emotional value.
That is precisely the strategy De Beers has adopted.
Earlier this year, the company announced organisational changes centred on strengthening its position as a premium natural diamond business, while highlighting renewed growth in demand for higher-value natural diamonds in key markets.
In other words, De Beers is no longer trying to convince consumers that laboratory-grown diamonds are inferior.
Instead, it is arguing that they belong in a completely different category.
The comparison is similar to natural pearls versus cultured pearls, or original artwork versus limited-edition prints.
Namibia’s premium advantage
Fortunately, Namibia occupies a unique position within the natural diamond industry.
Unlike many producers that focus on volume, Namibia is renowned for quality.
The country’s marine diamonds, recovered from the Atlantic seabed by Debmarine Namibia’s sophisticated mining vessels, are among the highest-value gem diamonds in the world.
They have been naturally polished over millions of years by ocean currents before settling on the seabed.
This gives Namibia a competitive advantage.
If natural diamonds increasingly become luxury collectibles rather than mass-market jewellery, quality will matter more than quantity.
That plays directly to Namibia’s strengths.
The uncertainty surrounding De Beers
The proposed sale of De Beers inevitably raises questions about Namibia’s future.
Would a new owner maintain current investment levels?
Would employment remain stable?
Would exploration continue?
These are legitimate concerns.
Botswana’s Minister for State President, Defence and Security, Moeti Mohwasa, recently confirmed that Anglo American has selected a preferred buyer while Botswana evaluates the “optimal structure” for any transaction, emphasising the importance of a financially strong long-term partner.
Namibia, too, has a strategic interest.
Through Namdeb Holdings, the Government already owns 50% of Namibia’s diamond operations.
That joint-venture structure provides an important measure of stability, regardless of who ultimately acquires De Beers.
Even so, ownership transitions often delay investment decisions and create uncertainty across the supply chain.
More than a diamond story
Perhaps the most important lesson from today’s downturn is not about diamonds at all.
It is about diversification.
For years, policymakers have spoken of reducing Namibia’s dependence on a single commodity.
Now the urgency is unmistakable.
Fortunately, the country is no longer solely a diamond economy.
Uranium has become one of Namibia’s fastest-growing export industries, supported by global interest in nuclear energy.
Gold production continues to expand.
Copper and zinc remain strategically important.
Critical minerals such as lithium, graphite and rare earth elements are attracting growing international investment, while offshore oil discoveries promise an entirely new chapter in the country’s natural resource story.
The future mining economy will almost certainly be broader than the one that carried Namibia through the twentieth century.
Beyond the sparkle
There is a tendency during commodity downturns to declare the end of an industry.
History suggests caution.
Diamonds survived the Great Depression, two World Wars, financial crises and countless recessions.
They will survive laboratory-grown diamonds as well.
But the industry emerging from this transition will look very different.
Natural diamonds will become increasingly defined by rarity, provenance and luxury.
Laboratory-grown diamonds will dominate the affordable jewellery market.
For Namibia, the challenge is not resisting change but adapting to it.
That means strengthening beneficiation, investing in branding Namibian diamonds, expanding downstream industries and using today’s mining revenues to build tomorrow’s economy.
The world’s fascination with diamonds may be changing, but Namibia’s opportunity remains.
The country’s greatest asset has never been the stones themselves.
It is the ability to transform finite natural wealth into lasting national prosperity.
That is a challenge no laboratory can manufacture, and no market downturn should be allowed to diminish.
