Sometimes all it takes is a disguise, a clever ruse, or a matter of minutes to make a jewel believed to be perfectly protected disappear. In Ciel, nos bijoux !, Nathalie Helal looks back at the jewelry thefts that have marked history, from the 17th century to the present day. From imperial palaces to museums, from safes to Parisian hotels, the author recounts these extraordinary cases, in which reality sometimes seems to borrow its plots from the cinema.

The book opens in London in 1671, with an attempt as audacious as it was reckless: that of “Colonel” Blood, who sought to seize the English crown after gaining the trust of its custodian. Three centuries later, methods have changed, but imagination remains at the heart of some of the most famous cases.
In Vienna, in 1998, Gerald Blanchard managed to steal Sisi’s Star,, a jewel associated with Empress Elisabeth of Austria, replacing it with a simple replica purchased from a souvenir shop. In Paris, in 1976, it was King Charles X’s diamond-encrusted sword that disappeared from the Louvre. In 2016, the Kim Kardashian case likewise demonstrated that the most coveted jewels are not always stolen from places one might consider impossible to breach
From Imperial Palaces to Parisian Hotels
Through these stories, Nathalie Helal is less interested in sensationalism than in the mechanics behind each case. How does one approach an object under such close surveillance? How can a guard’s attention be diverted, a security system bypassed, or a jewel made to disappear without arousing suspicion ?
The answers sometimes read like scenes from a film: makeup prosthetics, psychological manipulation, substitutions, getaway vehicles, or improvised escapes by bicycle or scooter. Each story exposes a different vulnerability and reminds us that the value of a jewel can also lie in its history, its symbolism and the fascination it inspires.
From the Crown Jewels of the Tower of London to the collections of the Louvre, from imperial jewels to pieces worn by celebrities, the book offers a parallel history of jewellery: one of coveted objects, stolen, sometimes recovered, but often lost forever.
By tracing the stories of these treasures, Nathalie Helal brings together the history of jewellery, true crime and detective stories. It is an unusual way of looking at jewellery: no longer simply as works of art or collectors’ pieces, but as objects steeped in history, capable of crossing centuries and inspiring the most unexpected acts of covetousness. A book for lovers of historic jewellery, true crime, history and notorious criminal cases, in which each jewel becomes the starting point for a singular story. Because behind the sparkle of a gemstone or the value of an object, there may lie a story of power, ingenuity and desire. Ciel, nos bijoux ! reminds us that certain jewels never cease to fascinate: even when they disappear, their stories continue to shine.
