The Imperial Diadem is made of a gold ribbon, fastened at the front by a jewel from a ring that belonged to the maternal ancestors of the former Emperor Terry I. In an attempt to make it look more similar to the diadems of the Byzantine Emperors, two gold chains are attached to each side of the diadem, which hang over the shoulders when worn. The Imperial Diadem was used by the Founder to crown Terry I during his coronation. Esmond III however took the Diadem from the Founder's hands and crowned himself, following the example of the Byzantine Emperors rather than European kings.
