De Beers Built the World’s Diamond Monopoly SCAM— So Why Is Its Empire Collapsing?

De Beers built the most powerful monopoly in modern history — not with guns or governments, but with a story. For over a century, one company controlled 90% of the world's diamond supply, convinced billions of people that a common stone was rare, invented the diamond engagement ring tradition, and made "A Diamond Is Forever" the slogan of the twentieth century. But today, that empire is collapsing. Anglo American has written down De Beers by $6.8 billion in just three years. Lab-grown diamonds now make up over 45% of U.S. engagement ring sales. And the company that manufactured scarcity is being made obsolete by a furnace.

In this video, we trace the full story — from a boy finding a pebble on a South African riverbank in 1866, to Cecil Rhodes' ruthless consolidation of the Kimberley mines, to Ernest Oppenheimer's Central Selling Organisation cartel, to the greatest advertising campaign ever run, to the blood diamonds crisis, and finally to the lab-grown revolution that is dismantling everything De Beers spent a century building.

This is the story of how one company rewired human culture — and what happens when the myth finally breaks.
