The crown is the most important regalia during a coronation. The first crowns of the French kings were a simple golden circle surmounted by four lily flowers. Louis XV wore three crowns during his coronation: that of Charlemagne, one set with prestigious diamonds for the release of the coronation, and one in enameled gold for the feast that followed. Only one remains, today preserved in the Salon d'Apollon in the Louvre. It was crafted by Augustin Duflos and adorned with two remarkable stones: the Sancy diamond and the Régent, acquired in 1717 by the regent Philippe d'Orléans. The crown also bears 282 diamonds, 64 colored stones (sapphires, rubies, topazes, and emeralds), and 230 pearls.
