The crown of Louis XV - the crown of the French kings in 1722 - 1789; the only remaining royal regalia of old-regime France.
History
The crown was created for the coronation of the juvenile King Louis XV in 1722 and was supposed to have relatively little weight. Gems from the Mazarin collection were used to decorate the crown, including the famous Sancy and Regent diamonds, as well as hundreds of other diamonds, sapphires, emeralds and rubies.
After the Great French Revolution, most of the royal jewels were lost, but this did not affect the crown of Louis XV. Although in 1885, the Third French Republic , experiencing financial difficulties, sold some precious stones from the crown, replacing them with glass imitations.
Currently stored in the Louvre Museum in Paris.
