The French Crown Jewels (French: Joyaux de la Couronne de France) and Regalia comprise the crowns, orb, sceptres, diadems and jewels that were symbols of Royal or Imperial power between 752 and 1870. These were worn by many Kings and Queens of France as well as Emperor Napoleon. The set was finally broken up, with most of it sold off in 1885 by the Third Republic. The surviving French Crown Jewels, principally a set of historic crowns, diadems and parures, are mainly on display in the Galerie d'Apollon of the Louvre, France's premier museum and former royal palace, together with the Regent Diamond, the Sancy Diamond and the 105-carat (21.0Â g) CĂ´te-de-Bretagne red spinel, carved into the form of a dragon. In addition, some gemstones and jewels (including the Emerald of Saint Louis, the Ruspoli sapphire and the diamond pins of Queen Marie Antoinette) are on display in the Treasury vault of the Mineralogy gallery in the National Museum of Natural History.
On 19 October 2025, eight of the jewels were stolen from the Galerie d'Apollon. The location of the stolen jewels is unknown; the Crown of Empress Eugénie was also initially stolen but was dropped during the thieves' escape and recovered in a damaged condition. The exact extent of the damage is still unknown, but was later revealed to be severe, with "delicate" repair needed for possible restoration.
