Hermann Ruissel

The middle of the pendant was a deep blue diamond cut as a pyramid or octahedron,[5] and weighing about 30 carats.

17 of these commissions stipulated that a duplicate of the work be made for his younger brother, Louis I, Duke of Orléans, as a gift.

[7] Ruissel made 18 gold buttons decorated with broom flowers and heraldic mottos for the 1396 marriage of Isabella of Valois to King Richard II of England.

Margaret III, Countess of Flanders, commissioned the work as a gift celebrating the New Year in 1403 for her husband, Phillip the Bold.

The necklace was later gifted to Sigismund of Luxembourg, King of Germany and Hungary, on the occasion of his visit to England in 1416.
