FAQ

Dig deeper on this story with frequently asked questions.

Napoleon's diamond brooch symbolizes imperial grandeur from the height of his reign, was lost during his defeat and retreat at the Battle of Waterloo in 1815, and subsequently became a war trophy given to King Frederick William III of Prussia, representing a major shift in European power.

The brooch, created around 1810, features a 13.04-carat oval diamond at its center surrounded by nearly 100 antique mined diamonds arranged in two concentric rows. It was likely designed to adorn Napoleon's bicorn hat on special occasions.

The diamond brooch sold for $4.4 million (over 3.5 million Swiss francs), which was 17 times higher than its high-end pre-sale estimate of approximately $250,000.

The auction was managed by Sotheby's in Geneva. The identities of both the seller and buyer of the brooch remain undisclosed.

Alongside the brooch, an unmounted 132.66-carat emerald that Emperor Napoleon I wore at his coronation in 1804, also historically connected to the House of Hohenzollern, was up for auction with a starting price estimated between $39,000 and $59,000.
