The Diamond Paradox: Rich beneath the soil, poor above it
· The South African
Picture the moment someone opens a little velvet box. The gasp. The tears.
Diamonds are the universal symbol of love, permanence, and arrival. “A diamond is forever,” as the most successful advertising slogan in history goes.

Now picture where that diamond actually came from.
Somewhere in central Africa, a man crawls through a tunnel the width of a washing machine. No ventilation, no safety equipment, a headlamp made from a flashlight and a rag.
A kilometre above him, there may or may not be a rebel militia waiting for their cut. The diamond he pulls out tonight might end up in Antwerp, then a jeweler’s window in Manhattan, and nobody along the way will ask too many questions.
This is the diamond paradox. The countries sitting on the most diamonds are, almost without exception, the ones where the least of that wealth reaches the people living above them.
The stone travels upward, but the money almost never does. And in almost every case, the reason is the same: the people being robbed have no meaningful say over what gets taken from them.
Angola: What Happens When No One Can Vote Them Out
Angola sits on diamond fields that stretch across its northeastern highlands, an Atlantic coastline, vast oil reserves, and roughly 36 million people who have seen almost none of it.
The country has been governed by the same party since independence in 1975, one of the longest-running single party dominances on the continent. Elections happen. Genuine opposition, not so much.
That political lockdown has a direct economic consequence: when the same people control the government, the army, the courts, and the mining concessions, there’s no mechanism to stop them from helping themselves. And they did.
The former president’s daughter, once ranked Africa’s richest woman, built her fortune through stakes across oil, diamonds, telecoms, banking and cement, routed through shell companies in Malta and Dubai including a diamond-marketing concession granted to a company she and her mother controlled.
Angolan prosecutors allege that transactions she and associates carried out with state-owned firms cost the government more than $1.1 billion, and courts have frozen assets on that basis.
No independent judiciary moved against it for years. No free press stopped it. No election threw anyone out over it. The money flowed because the systems that are supposed to catch that kind of theft, the basic democratic idea that public resources belong to the public, were either absent or controlled by the same people doing the taking.
Roughly a third of Angolans live in extreme poverty by recent World Bank estimates, and inequality remains among the highest in the world.
The diamond fields are still producing; much of their value still does not arrive. That’s not an accident of geography or bad luck. Its what extraction looks like when the people being extracted from have no real power to say stop.
The DRC: Where the Mine Is the War
The Democratic Republic of Congo sits on an estimated $24 trillion in untapped mineral wealth and has been at war, in various configurations, for three decades.
That is not a coincidence. It’s the logic of what happens when there’s no functioning state to hold anyone accountable.
The rebel group M23 seized Goma in January 2025 and by February controlled Bukavu as well.
Since taking the Rubaya coltan mines in April 2024, M23 has taxed roughly 120 tonnes of coltan a month, generating an estimated $800 000 a month.
The minerals cross into Rwanda, get mixed with legitimate supply, and are sold to manufacturers who ask essentially no questions.
More than seven million Congolese remain internally displaced amid the fighting. The Congolese government filed complaints against Apple subsidiaries in France and Belgium in late 2024 over allegedly conflict-tainted minerals in its supply chain; the French case was dismissed in February 2025, while a Belgian investigation is proceeding.
Apple’s market capitalization dwarfs the GDP of the entire African continent. The DRC’s economy, meanwhile, grew by about 6.5% in 2024 a slowdown from 8.6% growth in 2023, but growth, not contraction.
There’s no mystery about where the value went. The mystery is why the systems that were supposed to stop it keep failing. The answer, usually, is that the people harmed most have the least power to demand otherwise.
South Africa: Going Underground Just to Eat
South Africa has a different story, not warlords or offshore accounts, but ordinary men from Lesotho, Mozambique and Zimbabwe squeezing through holes in the ground with headlamps and nothing else.
They’re called zama zamas, which means roughly “those who take a chance” or “hustlers.”
The chance they take is extraordinary, and the reason they take it is straightforward: South Africa’s big mining companies shut down operations as ore grades declined and costs rose, leaving behind abandoned shafts and tens of thousands of workers with no jobs and, in many cases, no legal right to stay in the country they’d spent their working lives in. The companies left. The workers stayed. The poverty didn’t.
By 2024, illegal mining was costing the South African economy an estimated $1-3 billion a year, depending on the estimate, all of it underground, in shafts that officials largely ignored until the government sealed off access to a shaft.
Officials cut off food and water in an attempt to force miners to the surface, with a minister facing accusations of trying to “smoke them out.”
By the time the rescue operation concluded in mid-January 2025, at least 78 bodies had been recovered. Survivors described eating cockroaches and surviving on toothpaste.
South Africa has a modern constitution, an independent judiciary, and a free press.
It has all the machinery for accountability on paper. The syndicate bosses who built the criminal networks sending those men underground have largely faced no consequences. The machinery exists. It just doesn’t run for everyone equally, and that gap between rights on paper and power in practice is where people die.
Botswana: What Democracy Actually Did
In 1966, Botswana was one of the poorest countries on earth. Then geologists found diamonds.
What happened was different. Instead of letting a foreign company extract everything and leave, Botswana negotiated and kept negotiating, because it had a government stable enough, and accountable enough, to stay at the table.
It got a 50/50 joint venture with De Beers (Debswana), captured revenue through taxes and royalties, and built schools, hospitals and roads. The wealth, for once, didn’t just disappear, because citizens could ask where it was going and someone actually had to answer.
The story isn’t perfect. For decades, Botswana was entitled to sell only 25% of the rough diamonds produced from its own ground. Under a new 10-year sales agreement signed in February 2025, that rose to 30% immediately, climbing to 50% by 2035.
Progress, but also a country spending years negotiating for a larger share of something that was, by every natural right, entirely theirs.
Now the industry itself is in crisis.
Lab-grown diamonds have captured a significant share of the global market putting lab-grown stones at around 40-50% of US engagement ring sales.
De Beers reported a $288 million net loss in 2024 as rough diamond sales plunged roughly 44%.
Botswana’s response has been to pursue a majority, potentially controlling, stake in De Beers itself so that no future negotiation is necessary because the whole table belongs to them.
But why did it take six decades, and a market crisis, for the country that owns the diamonds to try to own the company that sells them?
The Ring on Your Finger
Every year, millions of people buy diamonds to mark the moments that matter most. They ask four questions: cut, colour, clarity, carat. Almost nobody asks the fifth: where did this come from? Who dug it up? What did they get paid?
The answers depend on the mine. A man with a rag for a headlamp. Almost nothing. Gone to a president’s daughter, a holding company in Malta, shareholders in London. Gone.
Angola, the DRC, South Africa, and Botswana all sit on some of the most extraordinary mineral wealth on earth.
In three of the four, ordinary citizens have seen relatively little of it.
Botswana changed the equation not through luck or better geology, but through something more specific to a system where the people making decisions could actually be held responsible for them, where citizens could ask where the money went and someone had to answer.
In Angola, the same party has ruled for fifty years and accountability has come slowly, if at all. In the DRC, an armed group taxes the mines directly while state authority struggles to hold. In South Africa, the men underground didn’t have anyone to ask.
The diamond doesn’t remember where it’s been. The people it came from do.
