Maison Boucheron was founded in 1858 by Frédéric Boucheron. From 1893, this jeweler was the first to set up at 26 Place Vendôme in Paris, in the private mansion occupied by the Countess of Castiglione, a famous courtesan of the Second Empire and mistress of Napoleon III.
This House has always followed the tastes of its contemporaries without restriction and was a pioneer in the art of transforming animals, plants and other insects into jewelry.
