Boucheron is a french luxury jewellery and watches house located in paris, 26 place vendome, owned by kering. The house of boucheron is a french family dynasty founded by frederic boucheron in 1858, with the opening of his first store in the galerie de valois, at palais-royal, during the heyday of the second french empire. He created his atelier in 1866 and a year later won the gold medal during the exposition universelle (1867). Paul legrand (1840-1910) worked as the chief designer for the house of boucheron from 1863-1867, and again 1871-1892. He is credited with the idea of combining pearls with diamond rondelles, first seen in boucheron products in 1889. The "rondelle" cut of diamonds was pioneered by bordinckx, who was also associated with boucheron. While legrand was head designer, in 1879, boucheron developed a clasp-less necklace, which was part of its show which won a grand prix for outstanding innovation in a jewellery collection at the 1889 world's fair.
