It is thought to have been cut from a 112-carat stone brought to France by the jewel trader Jean-Baptiste Tavernier and purchased by Louis XIV in 1668 as part of the French crown jewels. This stone, later called the French Blue, was recut into a 67-carat heart in 1673 and disappeared after the crown-jewel robbery of 1792.
