The Sancy

We’d like to share our passion and expertise for diamonds with you, which is why we’ve created the Blesq diamonds blog – read on for gripping tales and exciting news about the most precious gemstone on Earth.

One of the most famous diamonds in the world which not only impresses with its 55.23 carats, but also with one of the most adventurous journeys that such a top-class player can make. Dating back to the 15th century, Charles the Bold, Duke of Burgundy, wore the diamond as a lucky charm in the Battle of Nancy in 1477. Upon his fall, soldier may have sold the diamond to Portugal. In 1570, it received its name while in possession of Nicolas Harlay, Lord of Sancy, who later sent the diamond to Solothurn with a messenger, where he wanted to use it as security. The messenger never reached the destination. And so the diamond only came back to Nicolas Harlay after an extensive search for the deceased messenger, and the opening of his stomach. Due to a lack of money, he sold it again. The Sancy became part of the British crown jewels under Elizabeth I.

Afterwards, it came into the possession of the diamond-loving Louis XIV, but even here, it did not stay long. With the beginning of the French Revolution, it was amongst many other valuable diamonds stolen from the treasury in Paris. After some time in Russia, William Waldorf Astor acquired the Sancy diamond for his son’s wedding in 1906. For many years now it can be admired in the Apollo Gallery of the Louvre in Paris. Having not a pavilion, but two crowns, and cut in the shape of a shield, its yellow-pink fluorescence enchants its viewer.
