Historical jewels are set to be sold in Geneva on November 12th. Hundreds of natural stones, including an “extremely rare” pink diamond, are available. One of the centerpieces is a brooch that belonged to Napoleon.

The Napoleon Brooch

While French investigators are still searching for the jewels stolen from the Louvre Museum, other historical jewels are at the center of desire. In Geneva’s luxury hotels, a major auction is being organized by the house Sotheby’s on November 12th. Nearly 300 natural stones, of different sizes and colors, will seek buyers.

Among the exceptional jewels is a hat brooch created for Napoleon around 1810.

“This object was found when Napoleon fled the battlefield of Waterloo in 1815. It is the first time in history that such an object has been offered to the public,”

observed Andres White Correal, head of Sotheby’s jewelry department, on LCI on Saturday, November 8th. Adorned with a 13-carat oval diamond, which is surrounded by nearly 100 cut diamonds, the brooch is estimated to be worth between 130,000 and 220,000 euros.

Prestigious Watches

The auction will also highlight prestigious watches, such as the one worn in 1927 by endurance swimmer Mercedes Gleitze, the first British woman to swim across the English Channel. It is also one of the first waterproof wristwatches.

“Given its historical importance, it is of course very difficult to put an estimate on a piece like this. It is really up to the market to determine the final value of the piece. We are starting with a bid of 1 million Swiss francs and we have already received a few inquiries,”

explained Benoît Colson, director of Sotheby’s watch department in Geneva.

The Star of the Auction

But the star of this auction is a bright pink diamond, over 10 carats, with rounded corners, set on a platinum ring. Estimated value? 17 million euros.

“It is a truly exceptional piece, extremely rare on the market. Owning a stone of this color, this purity, and this size is simply extraordinary,”

emphasized Jessica Wyndham, head of High Jewelry at the British auction house.
