The emblem had a third great gem known as "The Côte de Bretagne dragon". Its replica was based on a wax likeness sculpted by Pascal Monney, who had based his recreation from three-dimensional scaled pictures of the original object which had been made by French artist François Farges; Farges, in turn, had seen the original objects displayed at the Louvre's Galerie d'Apollon. In addition, artist Etienne Leperlier cast a "crystal" lead glass duplicate of the wax replica of the carved Côte de Bretagne. Its pigmentation is made out of gold and manganese pigments to simulate as close as possible the original color of the spinel.
