The Antwerp Diamond Centre vault was supposed to be impenetrable. Located two floors below the Antwerp Diamond District — the hub of the global diamond trade where $200 million in gems changes hands every single day — it was protected by ten layers of security that read like a heist movie prop list:
- A 100-million-combination lock
- Infrared heat sensors
- A seismic detector that could sense vibrations from drilling or explosions
- Magnetic sensors on the vault door
- A light sensor that triggered if anyone opened the vault door in darkness
- Multiple CCTV cameras
- A private security guard
The vault held 160 individual safe deposit boxes used by diamond traders to store loose stones, gold, jewellery, and cash. The total value was estimated at over $100 million.
In February 2003, a team of Italian thieves led by a man named Leonardo Notarbartolo cracked every single layer.
They had rented an office in the Diamond Centre. They had spent three years studying the building, its routines, and its security systems. They built a replica of the vault door in a rented warehouse. They practised until they could defeat each security measure in sequence.
On the weekend of February 15-16, 2003, they walked into the vault and emptied 123 of the 160 safe deposit boxes. The haul: an estimated $100 million in diamonds, gold, jewellery, and other valuables.
It should have been the perfect heist. But one of the team members, trying to dispose of evidence, dumped garbage bags in a forest outside Antwerp. Inside the bags: half-eaten salami sandwiches, diamond-encrusted envelopes with fingerprints, and — critically — a videotape from one of the vault's own security cameras that hadn't been properly destroyed.
A local farmer found the bags. The police traced the DNA on the sandwich to the team. Leonardo Notarbartolo was arrested within weeks.

The heist breakdown
How the team defeated every security layer — from polyester to fool infrared sensors to hairspray on the light detector. Every solution was low-tech and brilliant.
What you now know
- A team of Italian thieves spent three years casing the Antwerp Diamond Centre before stealing an estimated $100M+ in diamonds, gold, and jewellery
- They defeated 10 layers of security including infrared sensors, seismic detectors, and a 100-million-combination lock — often with absurdly low-tech solutions
- The heist was undone when one member dumped evidence in a forest, including DNA-laden salami sandwiches and an undestroyed security camera tape
