It was tradition for French kings to have their own coronation crowns made. The coronation crown of Louis XV is composed of a satin cap encircled by a band of gilded silver and topped with diamonds forming a fleur-de-lis. It was worn only once, at the coronation in 1722. Shortly thereafter, the crown was delivered to the Royal Abbey Church of Saint-Denis (today it’s the Basilica of Saint-Denis) where it resided with other regalia. In 1729, Louis XV requested that the 282 diamonds, 64 gemstones and 237 pearls be replaced with paste. The crown, with its imitation paste jewels, has been at the Louvre since 1852.
