The Antwerp Diamond Heist
The Thieves Who Beat Ten Layers of Security
On a February weekend in 2003, four men crawled on their bellies through the basement of the Antwerp Diamond Centre, defeated ten layers of supposedly impenetrable security with hairspray and electrical tape, and walked out with over $100 million in diamonds. They were undone by a half-eaten sandwich.
It took 28 months of planning, a replica vault, and a man who could duplicate a key from a photograph.

Safe deposit boxes in the Antwerp Diamond Centre vault, two floors below street level. The crew broke into 109 of them on a single weekend, extracting approximately 120,000 carats of loose diamonds.

Aside from 17 diamonds in the mastermind's home safe, the $100M+ haul has never been found.
The Evidence
Ten Layers Defeated
The vault was protected by cameras, light sensors, infrared detectors, magnetic locks, Doppler radar, seismic sensors, a combination lock with 100 million possible sequences, a foot-long key, window alarms, and private security guards. The crew defeated every single one — using hairspray, electrical tape, Styrofoam, and patience.
The Haul
From 109 broken safe deposit boxes, the crew extracted approximately 120,000 carats of loose diamonds, gold bars, cash, rare coins, and jewelry. The Guinness Book of World Records certified it as the largest diamond heist in history. Most of the loot remains missing over two decades later.
The Sandwich
The crew's logistics man dumped garbage bags in a forest near the E19 motorway instead of destroying them. A local shopkeeper found the bags, which contained Diamond Centre envelopes, tools, a videotape — and a half-eaten salami sandwich. The DNA matched mastermind Leonardo Notarbartolo.
The Heist of the Century
The Infiltration
Leonardo Notarbartolo rents an office in the Antwerp Diamond Centre for $700/month, posing as an Italian gem importer. He installs hidden cameras and spends 28 months studying the vault's ten security layers from the inside.
The Heist
Over Valentine's Day weekend, the crew enters through a neighbouring building, defeats all ten layers, and empties 109 safe deposit boxes. Estimated value: over $100 million in diamonds, gold, and jewelry.
The Mistake
Garbage bags containing evidence — including a DNA-laden sandwich — are dumped in a forest instead of being destroyed. A local shopkeeper finds them and calls the police. Notarbartolo is arrested within five days.
The Verdict
Notarbartolo sentenced to 10 years. Three accomplices receive 5 years each. The "King of Keys" — the man who forged the vault key — is never identified or caught. Over $100 million remains unrecovered.
The Documentary
Netflix releases "Stolen: Heist of the Century." Notarbartolo appears on camera for the first time: "We felt proud of doing something so strong and powerful."
Key Figures
Leonardo Notarbartolo
A professional thief from Turin who spent 28 months posing as a gem importer inside the Diamond Centre. He studied every guard rotation, every camera angle, and every security system — then recruited a crew from the School of Turin to execute the most technically sophisticated heist in history.
The King of Keys
The only team member never identified or caught. He duplicated the Diamond Centre's supposedly impossible-to-forge, foot-long vault key from video footage alone. His real name remains unknown to this day — the one mystery the heist of the century never solved.
Every Lock Is a Puzzle
The most technically sophisticated theft in history was undone by the most basic failure of discipline — a garbage bag dumped in a forest.
Twenty-eight months of preparation. A replica vault. Ten defeated security layers. And a sandwich that should have been burned.
