Louis Alphonse, Duke of Anjou
Their father has conferred upon them the historic French titles of, respectively, Duke of Burgundy ("duc de Bourgogne"), and Duke of Berry ("duc de Berry"). (In Spain, the twins are "Don" Luis and "Don" Alfonso de Borbón Vargas). Prince Louis, as Legitimist Dauphin of France, is expected to succeed his father as head of the French royal house, the senior Bourbon/Capetian line, in Legitimist reckoning. However, under Spanish law, and assuming Felipe VI does not in future father a son, the Spanish crown will be inherited by his elder daughter Leonor, Princess of Asturias, who will become queen regnant, and if Felipe does have a son, that son will inherit the Spanish throne regardless of the genealogical seniority of the Anjou branch. Louis and Alphonse were baptised on 5 September 2010 at St Peter's Basilica in Vatican City. Louis' godparents were Arancha Martínez-Bordíu and Francisco D'Agostino and Alphonse's were Amparo Corell de Trenor, and Lorenzo Perales.
French Crown Jewels
The French Crown Jewels () comprise the crowns, orb, sceptres, diadems and jewels that were symbols of Royal power between 752 and 1825. These were worn by many Kings and Queens of France. The set was finally broken up, with most of it sold off in 1885 by the Third French 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 "Côte-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 Muséum national d'histoire naturelle.
