Napoleon's Lost Diamond Brooch Surfaces for Auction

A historically significant diamond brooch, once belonging to none other than Napoleon Bonaparte and reportedly recovered amidst the chaos following the Battle of Waterloo, is set to make its auction debut this November. This unique piece, distinct from the recently stolen French crown jewels from the Louvre, will be a highlight at Sotheby’s Royal & Noble Jewels sale in Geneva on November 12. According to historical accounts, Napoleon himself abandoned the brooch during his retreat after his decisive defeat in 1815, and it subsequently became a cherished possession of the victorious King of Prussia's descendants for centuries.

Crafted in a Parisian atelier around 1810, the circular brooch features a striking oval diamond weighing over thirteen carats at its core, encircled by nearly a hundred old mine cut diamonds of various shapes and sizes. It is believed that this magnificent piece frequently adorned Napoleon’s iconic bicorne hat on significant occasions. Sotheby’s has projected the brooch to fetch between $150,000 and $250,000, reflecting both its material value and profound historical resonance.

Offered as a spoil of war merely three days after Napoleon's defeat, the brooch found a lasting home within the House of Hohenzollern, the former German imperial dynasty, where it remained for centuries. Its illustrious line of ownership includes King Friedrich Wilhelm III, passing down through generations to Kaiser Wilhelm II, Queen Victoria's grandson and the last German emperor, and eventually to his grandson, Louis Ferdinand, Prince of Prussia. In recent years, the esteemed artifact has been part of a different private collection, preserving its legacy before this momentous auction.

In today's volatile global market, collectors are increasingly drawn to rare, historically rich items as dependable stores of value. Sotheby's annual Royal & Noble auction specializes in showcasing such illustrious jewels, celebrated for their exceptional provenance. Past sales have included a diamond necklace potentially linked to a scandal involving Marie Antoinette, which sold for $4.8 million. One of the most legendary auctions occurred in 1987, when a collection belonging to the late Duchess of Windsor achieved a staggering $50 million, far exceeding its initial estimates.

While Napoleon’s diamond brooch stands as the undeniable showpiece of the upcoming auction, the sale will also present other exquisite items. Among these is a beautiful diamond ring that once graced the collection of Neslishah Sultan, one of the last princesses of the Ottoman Empire, further enriching the auction's tapestry of royal and noble heritage.
