Over the weekend of 15–16 February 2003 a vault at Antwerp's Diamond Centre was emptied of stones, jewellery and cash. Leonardo Notarbartolo was convicted; most of the haul was never recovered.
Also called: School of Turin · Antwerp Diamond Centre
During the weekend of 15–16 February 2003, tenants' safe-deposit boxes in the vault of the Antwerp Diamond Centre — a building in the city's tightly policed diamond quarter — were emptied of loose diamonds, jewellery, gold and cash. Contemporary Belgian and insurance estimates clustered around $100 million, a figure that remains a 2003-order-of-magnitude mark rather than a locked inventory.
Belgian police arrested Leonardo Notarbartolo, an Italian who rented an office in the building, after rubbish discarded near Brussels yielded Diamond Centre paper and video stills. He and several associates, later nicknamed the School of Turin in English-language magazines, were tried in Antwerp. Notarbartolo received a multi-year sentence; others were convicted in absentia or later. Appeals and later interviews did not return the stones.
The status is mixed because a court named people and a building, while the goods themselves mostly never reappeared. This page records what was taken, who was convicted and what investigators did afterward. It does not describe how a vault is opened.

A convicted crew and a missing inventory
Antwerp 2003 is the type case of a diamond-district theft that produced prison time without producing the diamonds.
What the boxes held
The Diamond Centre vault served many small firms, not a single De Beers stockpile. Boxes held loose stones, mounted jewellery, gold and cash belonging to different tenants. That is why published totals vary: there was no one company inventory to audit against a single ledger.
Insurers and the Antwerp diamond trade treated the weekend as a shock to a district that markets itself on secure custody. The unrecovered portion matters more than the courtroom names: stones that re-enter cutting and trading channels become hard to identify as the 2003 lot.
From a forest dump to an Antwerp dock
Investigators reconstructed the weekend after a discarded cache of papers, videotape and building-related material was found near the Forêt de Soignes outside Brussels. That find, not a confession in the vault, tied Notarbartolo's rented office to the loss.
Arrests followed in Antwerp. English readers later met the story through Wired and the 2010 book Flawless by Scott Andrew Selby and Greg Campbell, which named the School of Turin label. Those accounts are journalism, not a vault manual, and this atlas uses them only for public names and court outcomes.
Trials without a pile of stones
Notarbartolo was convicted in Antwerp and sentenced to a term of years; he served time in Belgium. Co-defendants received sentences in person or in absentia. Later Italian and Belgian proceedings added footnotes. None of those judgments included a public restitution of the full 2003 estimate.
Notarbartolo later gave interviews that disputed the official scale and blamed others. Courts had already treated him as a central figure. The mixed status of the dossier is exactly this split: legal responsibility on the record, property still off it.
A district, not a new statute
Belgium did not pass a famous named 'Antwerp Act' after 2003. The diamond quarter reviewed building access, tenant screening and vault practice. Those are trade and policing changes, not a global treaty.
English cultural reach stayed below Gardner or the Great Train Robbery: a specialist heist story, a magazine set piece, fewer films. The legal impact score in this atlas is therefore modest; the scale score is not.
Over the weekend of 15–16 February 2003, at the Antwerp Diamond Centre in the city's diamond quarter. Tenants discovered emptied safe-deposit boxes when business resumed. Belgian police opened the investigation that week.
How much was taken?
Contemporary reports and later English books used a figure on the order of $100 million in diamonds, jewellery, gold and cash. Because many tenants used the vault, there is no single audited public inventory. The number is a 2003-scale estimate, not a courtroom exhibit total.
Who was convicted?
Leonardo Notarbartolo, who rented space in the building, was the best-known defendant and served a Belgian sentence. Associates later grouped in English as the School of Turin were convicted in person or in absentia. Convictions did not include recovery of most of the goods.
Were the diamonds recovered?
Most were not. A discarded cache of papers and tape near Brussels helped investigators, but it was not the haul. Loose stones are hard to identify once recut or resold. The recovery column remains the open half of a mixed case.
What is the School of Turin?
An English-language nickname, popularised after the fact, for the Italian group around Notarbartolo. It is not an official Belgian court title. The phrase signals a crew from the Turin area, not a licensed school.
Was this the De Beers vault?
No. The Diamond Centre held many tenants' boxes. English headlines sometimes blurred the building with the wider Antwerp trade or with De Beers. The public record is a multi-tenant vault in the diamond quarter.
Why is the status mixed rather than convicted?
People were convicted, so the file is not unsolved in the Gardner sense. The goods were not returned and some defendants were tried in absentia, so it is not a fully closed restitution case. Mixed is the honest token.
Did Belgium change diamond law after 2003?
There was no single celebrity statute. The district and building operators reviewed access and custody. Later English coverage treated Antwerp as a security parable for gem centres, not as the birth of a new international convention.
