The fleur-de-lys tiara comes from the Bourbon-Parma family and belonged to Maria Anna, Princess of Bourbon-Parma. The fleur-de-lys, a Bourbon totem, has long been used by the French royal family for its coat of arms and various decorations. The diamonds used were originally set in the Order of the Holy Spirit of King Charles X. They were removed from the Order and passed on to Robert I, the great-grandson of Charles X and ruler of the Duchy of Parma, the father of Prince Elias. The diamonds are then re-set in the fleur-de-lys tiara by Viennese jeweler Hübner on the family's commission.
