ALONG A GRAVEL ROAD
FROM ABIDJAN TO TORTIYA
‘Two large men in T-shirts came in and dragged us out. They marched us through the village and shoved us into a car. As we drove into the darkness I remember thinking, very clearly – this is how a foreigner disappears in Africa. I had told no one that I was going to Tortiya. Everyone thought I was in Abidjan.’
A former president of the London Diamond Bourse, at whose head he served from 2018 through 2024, Alan Cohen is a member of the World Diamond Council’s Board of Directors and also of its Kimberley Process Task Force.
South African-born, he left the country as a young diamantaire, settling in London and becoming part of United Kingdom’s diamond sector. When the Russian diamond industry opened to the international trade in 1990, he relocated to Moscow, where he lived and worked for 16 years.
After returning to London he became active in the public life of the industry, first at the London Diamond Bourse, and later at the World Federation of Diamond Bourses and the World Diamond Council.
MARCH 31, 2026
A few small, unrelated events brought this memory back to me.
I recently was sent a link to a wonderful exhibition in Paris. It featured the Al Thani Collection, which was being shown in collaboration with the Victoria and Albert Museum in London.
It reminded me of the first time I saw an Al Thani exhibition. That time it was in London itself, years ago, and a close friend from Geneva had flown especially to see it together with me.
And then, after receiving the link about the current Paris exhibition, the same friend messaged to say that, since she was again in London for a few days, could my wife and I meet her at the V&A and see the jewelry that is on display right now.
So, we met there a few days ago. And, standing in front of the pieces in the exhibit, all objects from different times and continents, I was struck by a very a simple epiphany. Diamonds invariably travel a long way before ever reaching a museum case.
And then suddenly I remembered Tortiya.

The promise of perfect parcel of rough
Decades ago, the same friend from Geneva sent me on a journey to Côte d’Ivoire.
I earlier had bought a parcel of perfect rough diamond crystals from one of her contacts, and he had spoken about “lots more” where they came from. His name was Alfa.
It was 1987. I was due to fly from London to South Africa with my wife and our six-month-old daughter to visit my parents, who had not yet met either of them.
But Alfa convinced me that there was another amazing parcel waiting for me in Abidjan. I had very little time to complete the business – three days in total to fly in and get back to join my family, so that we could journey on to South Africa.
My flight into Abidjan was long delayed and I arrived at 4:00 AM, instead of 8:00 PM the evening before. Alfa was nowhere to be seen.

I found a room at a local hotel and went to bed.
I was woken several hours later by banging on my door. Alfa had found me – how, I still don’t know. Within minutes he was talking about hiring a car and driving north to Tortiya, some 550 to 600 kilometers away. It would cost $1,000, he said.
I was not particularly taken aback, for I had heard this kind of story about “expenses” before, not only in Côte d’Ivoire, but also Brazil, Siera Leone, Lesotho and other places. However, before leaving London, I had been very clear about what I was prepared to do. I had limited time, and everything needed to be legal. The goods had to be shown in Abidjan.
I had even arranged, through another local dealer, the funds that may be required to complete the purchase properly and then ship the diamonds to London.
So, I refused Alfa. I told him I was staying in Abidjan and would likely fly home later that day.
An hour later he returned. He said that a friend, also named Alfa, would drive us to Tortiya for $250 plus petrol and expenses. Reluctantly, I agreed.
The incident in the shack in the village center
The road north began smoothly enough, all the way to Yamoussoukro. But it then slowly deteriorated, and beyond Bouaké it was gravel and stone all the way to Tortiya.
We had two or three punctures on the way, forcing us to make repairs by the roadside. Through the dust and heat, it was only patience and the promise of perfect crystals that kept me going.
We eventually arrived at what passed for accommodation – a series of three-sided wooden structures, with their fronts covered with mosquito netting and chicken wire. There was no electricity except for a small generator powering a fridge with beer inside. Each hut had an air-conditioning unit fitted into the wall, but none of them were connected to power.
The Alfas left to “arrange the goods.”
When they returned, they took me into the village center. Outside a small shack stood a line of perhaps 30 people. Inside there was a lamp run off a generator, a white sorting pad, a scoop, tweezers, a portable scale, even a head loupe. I set myself up.
Small parcels were brought in. They contained stones of less than a carat, two carats, five, and perhaps 10 carats at most. All were low-end alluvial goods.
By the seventh or eighth parcel, irritation was setting in. I was still waiting for the “perfect crystals” I had been promised.
Under arrest in the African bush
Then everything shifted, quite dramatically.
A large man burst into the room shouting. Even with my limited French, I understood there was a problem. We were rushed outside. Now it was fully dark, and I am talking about the kind of darkness only the bush produces. I had to keep my hand on Alfa’s shoulder to avoid losing him.
The second Alfa and our car were gone.
We were taken to a small hut. A woman opened the door, a baby at her breast, and we were told to stay inside and open for no one. Alfa suggested that if I had any cash, I should give it to him so he could “sort it out.” I declined.
Then there was banging at the door. “Police,” we heard from the other side.
Two large men in T-shirts came in and dragged us out. They marched us through the village and shoved us into a car. As we drove into the darkness I remember thinking, very clearly – this is how a foreigner disappears in Africa. I had told no one that I was going to Tortiya. Everyone thought I was in Abidjan.
Ten or 15 minutes later, I saw a sign: “Police.” The relief was physical.
At the station stood the line of sellers I had seen earlier, along with the other Alfa and his car. The first Alfa and I were questioned, with me being interrogated through a young translator.
I was indignant, for I had checked my legal position carefully. I was told that Alfa should have registered me upon arrival. He claimed he had tried but the station had been closed. I had no way of knowing if that was true.
They asked me about what I had bought.
“Nothing,” I replied. “The goods were not of the quality or price I would pay.”
The police searched me. They found only my notebook, pages listing each parcel, the asking price, my valuation, and a large “NO” beside each one.
No money had changed hands. No stones had been purchased.
The Alfas were strip searched. I was told I would be taken back to the camp and a policeman stationed outside my hut so I would not “run away.” I laughed. I had no idea where we were and did not speak the language. Running anywhere seemed overly ambitious.
Freedom and my Belgian fixer
The next morning, the young translator suggested we see the mayor. His house was unmistakable. Outside was a new Mercedes and on the roof a large satellite dish
He listened to my story, and I understood just enough French at the right moment: “Pas de problème. Libérez-les.” I was free to go. Or so I thought.
Back at the police station, the commander, now resplendent in uniform and medals, informed us that our names had been sent to Abidjan. Until he received confirmation that we were not “wanted,” we would have to remain – two or three days perhaps.
Despondent, I walked outside and sat on a bench.
Then a car arrived. A white man stepped out, flanked by two, armed guards. Around his neck was hung a large Star of David. He spoke English. He was Belgian, working for a company I knew well in Antwerp.
I explained my situation.
“How much money do you have?” he said.
“About $2,000,” I replied.
“Wait,” he said.
The Belgian went inside, and soon after returned. “Fixed,” he said. “No problem, but there are two conditions, you give the commander a lift to Bouaké, and you leave now.”
To this day I do not know where the money went. I prefer to imagine that the Belgian kept it all. But I presume the commander received a share.
It’s the journey that counts
We drove south immediately and went straight to the airport. My flight from Abidjan routed through Ouagadougou, Niamey, and Paris. I do not remember falling asleep, only waking when we landed in France.
It had been a grueling experience, but when I thought about it, it was not particularly out of the ordinary. I had not found what I was looking for, but neither had I been cheated.
True, I was out $2,000, but that was on me. I used to joke that visitors in Africa walk around with an invisible sign above their heads that says, “I’m in a hurry.” And the remarkable thing is that only the locals can see the sign.
I had three days. A return ticket. Family waiting. Everyone else was operating on a different clock.

It would take me years, and time spent in several continents to understand that this is not a uniquely African thing. It is simply how power works wherever one party must leave and the other can stay.
Those stones in Tortiya were low-end alluvial goods. No surprises. Nothing purchased.
But they had already traveled, on foot, by motorbike, across riverbeds and rough tracks, long before they reached my sorting pad. And I also had traveled far to see them.
There is something wonderfully irrational about all this in hindsight. Today we would measure the margin, the risk, the time and the tires, and then decide that the potential reward does not justify the effort.
But diamonds do not begin in spreadsheets. They begin on gravel roads
What has changed, and what remains consistent
Standing in the V&A, looking at jewels whose journeys are documented in dynastic records and auction catalogs, I was reminded of something I wrote recently about ethics and traceability in our industry.
We currently are redefining what it means for a diamond to be “ethical.” Increasingly, that definition is anchored in technology, in scanning, blockchain records, and other end-to-end digital tracking.
On the surface, it is hard to argue with these innovations. Responsible sourcing is something the trade has supported for decades.
But the further we move toward defining ethics by technological access, the easier it becomes to forget where many diamonds actually begin their journey – in places without scanners, without stable infrastructure, and sometimes without clarity of process.
For decades, ethical sourcing was judged by conduct – lawful production, legitimate ownership, compliance with national and international rules. None of that required a QR code.
Diamonds are inanimate. There is no such thing as a good or a bad diamond. Long before they sit beneath the glass of a museum display case, the very same stones have passed through multiple hands, through many systems and through moments of uncertainty.
The diamonds themselves have not changed. The only things that have are the frameworks around them.
