In 1749, Louis XIV's great-grandson, Louis XV, had the French Blue set into a more elaborate jewelled pendant for the "Order of the Golden Fleece" by court jeweler André Jacquemin. The assembled piece included a red spinel of 107 carats shaped as a dragon breathing "covetous flames", as well as 83 red-painted diamonds and 112 yellow-painted diamonds to suggest a fleece shape. The piece fell into disuse after the death of Louis XV. The diamond became the property of his grandson Louis XVI. whose wife, queen Marie Antoinette, used many of the French Crown Jewels for personal adornment by having the individual gems placed in new settings and combinations, but the French Blue remained in this pendant except for a brief time in 1787, when the stone was removed for scientific study by Mathurin Jacques Brisson, and returned to its setting soon thereafter.
