Queen Maria had reportedly told her husband "I want nothing modern that another queen might have. Let mine be all medieval."
The new crown was made of gold mined from the Transylvania region of Romania and constructed in 1922 in Alba Iulia. It was modeled on one having belonged to Milica Despina of Wallachia, the consort of a 16th-century Wallachian prince. It contains rubies, emeralds, amethyst, turquoise and opals and weighs 4 pounds (1.8 kg). Grains of wheat decorate the base of the crown topped by eight large and eight small flower ornaments connected by interlacing branches. A globe and cross sit atop the eight arches above the flower ornaments and a pendulum, supposedly copied from ancient Byzantine head ornaments, hangs from either side of the headband just above the ear, each bearing the coat of arms of Romania. From each of these pendula hang three chains, each with a cross within a gold circle at the end.
PS
King Carol was a cold man who was always focused on the prestige of the dynasty he had founded. His wife, Elizabeth, claimed he 'wore the crown in his sleep'.
