The Louvre Museum in Paris has announced that the historic crown of Empress Eugénie, which was severely damaged during a brazen daylight heist in October 2025, can be fully restored. The crown, one of only three surviving French sovereign crowns, was found mangled on the floor of the Apollo Gallery after thieves smashed their way into its display case.
Details of the Damage and Survival
The crown of Empress Eugénie, the wife of Napoleon III, was discovered crushed and badly deformed following the audacious theft. A fragment containing a diamond-and-emerald element was located nearby. Museum officials stated that some of the deformation likely occurred when the crown was forced through a narrow slot cut by the thieves using an angle grinder, followed by a violent impact that crushed it.
Despite the significant damage, Louvre experts have confirmed that almost all of the crown's original components remain intact, making a comprehensive restoration feasible. The emerald-and-diamond globe at the top of the crown is unharmed, and all 56 emeralds survived the ordeal.
Specific Losses and Recoveries
Of the crown's 1,354 diamonds, only ten tiny stones at the base are missing, with nine others detached but preserved. Structurally, one hoop was torn off and lost. Among the eight diamond-and-emerald palmettes and eight gold eagles that adorn the crown, one eagle is missing, while four palmettes became detached but were recovered.
The Heist and Investigation
The damage occurred during the heist on 19 October 2025, when thieves broke into the world's most visited museum in broad daylight. Using power tools, they stole eight items of jewellery, including tiaras, a brooch, an emerald necklace, and earrings, collectively encrusted with thousands of diamonds worth approximately €88 million (£76 million). Prosecutors report that the thieves were inside the Louvre for less than four minutes before escaping on scooters.
To date, four men have been arrested on suspicion of carrying out the raid, but investigators believe the mastermind behind the heist remains at large. The day after the theft, the judicial police handed the recovered crown to the Louvre’s Department of Decorative Arts for assessment.
Restoration Process and Historical Significance
Given the crown's symbolic importance and the unprecedented nature of the repair, the Louvre will appoint an accredited restorer through a competitive process to comply with legal requirements. An advisory committee of experts, chaired by Louvre President-Director Laurence des Cars, will oversee the restoration work.
Commissioned by Napoleon III for the 1855 Universal Exhibition, Empress Eugénie’s crown was crafted by imperial jeweler Alexandre Gabriel Lemonnier, with sculptor Gilbert designing the long-winged eagles and jeweler Pierre Maheu overseeing the workshop. After the fall of the Empire, the crown was returned to Eugénie in 1875, a twist of fate that saved it from the mass sale of crown jewels ordered by the Third Republic in 1887. Passed down through the Bonaparte family, it was acquired by the Louvre in 1988.
Though never used in a coronation, it is one of only three sovereign crowns preserved in France, alongside the crown of Louis XV and the so-called crown of Charlemagne made for Napoleon I. The restoration project represents a critical effort to preserve this irreplaceable piece of French heritage for future generations.
