A remarkable piece of history connected to one of Europe's most famous military leaders has found a new owner at a staggering price. Sotheby's auction house has confirmed the sale of a diamond brooch that belonged to Emperor Napoleon I, which was lost during his forces' retreat from the Battle of Waterloo.
The Historic Jewelry Piece
The exquisite brooch, dating back to approximately 1810, features an old mine-cut diamond design that could be worn either as a brooch or pendant. This stunning piece of jewelry was part of Napoleon's personal collection during the height of his power, representing the opulence of the French Empire period.
What makes this artifact particularly significant is its connection to one of the most pivotal moments in European history. The brooch was lost during Napoleon's frantic retreat after his defeat at the Battle of Waterloo in 1815, adding a layer of historical drama to its already impressive provenance.
The Record-Breaking Auction
On Thursday, November 6, 2025, Sotheby's Geneva hosted a preview event where the diamond brooch was displayed to potential buyers. The auction house carefully presented the historical artifact, emphasizing its unique connection to Napoleon Bonaparte and the circumstances of its disappearance.
The final hammer price reached an impressive US$4.4 million, far exceeding initial estimates and demonstrating the enduring fascination with Napoleon-era artifacts among collectors. The sale highlights the premium that historical items connected to famous figures can command in today's auction market.
Enduring Legacy of Napoleon Artifacts
This sale continues a strong trend of Napoleon-related items achieving remarkable prices at auction. Collectors remain captivated by artifacts from this turbulent period in European history, particularly those with direct connections to the emperor himself.
The brooch's journey from Napoleon's possession to its recent sale spans more than two centuries, during which it passed through unknown hands before resurfacing for this landmark auction. Its survival and eventual reappearance add to the mystique surrounding Napoleon's lost treasures.
This significant sale at Sotheby's demonstrates that historical artifacts with compelling stories continue to capture the imagination of collectors worldwide, commanding prices that reflect both their material value and their importance to European history.
