This traditional headpiece sits atop the head and usually features jeweled or beaded embellishments.
One of the things a bride may choose to wear, it is a fully circular gemstone or bead adorned head piece that is larger than both a half crown and tiara. In Greek Orthodox Christian weddings; both the bride and groom have crowns placed on their head by the Koumbaro, who then swaps the crowns between the couple three times. (See Koumbaro) The precursor to the crown was the browband called the diadem, which had been worn by Persian emperors, was adopted by Constantine I, and was worn by all subsequent rulers of the later Roman Empire. Numerous crowns of various forms were used in Antiquity, such as the White crown, Red Crown, combined Pschent crown and blue crown of Pharaonic Egypt. The corona radiata, the "radiant crown" known best on the Statue of Liberty, and perhaps worn by the Helios that was the Colossus of Rhodes, was worn by Roman emperors as part of the cult of Sol Invictus prior to the Roman Empire's conversion to Christianity. It was referred to as "the chaplet studded with sunbeams” by Lucian, about 180 AD (in Alexander the false prophet). Perhaps the oldest Christian crown in Europe is the Iron Crown of Lombardy, of Roman and Longobard age, later again used to crown modern Kings of Napoleonic and Austrian Italy, and to represent united Italy after 1860. In the Christian tradition of European cultures, where ecclesiastical sanction authenticates monarchic power, when a new monarch assumes the throne in a coronation ceremony, the crown is placed on the new monarch's head by a religious official. Some, though not all early Holy Roman Emperors travelled to Rome at some point in their careers to be crowned by the pope. Napoleon, according to legend, surprised Pius VII when he reached out and crowned himself, although in reality this order of ceremony had been pre-arranged: see coronation. Today, only the British Monarchy continues this tradition as the sole remaining anointed and crowned monarch, though many monarchies retain a crown as a national symbol in heraldry. The French Crown Jewels were sold in 1885 on the orders of the Third French Republic, with only a token number, with their precious stones replaced by glass, held on to for historic reasons and displayed by the Louvre. The Spanish Crown Jewels were destroyed in a major fire in the eighteenth century while the Irish Crown Jewels (actually merely the Sovereign's insignia of the Most Illustrious Order of St Patrick) were stolen from Dublin Castle in 1907. Special headgear to designate rulers dates back to pre-history, and is found in many separate civilizations around the globe. Commonly, rare and precious materials are incorporated into the crown, but that is only essential for the notion of crown jewels. Gold and precious jewels are common in western and oriental crowns. In the Native American civilizations of the Pre-Columbian New World, rare feathers, such as that of the quetzal, often decorated crowns; so too in Polynesia (e.g. Hawaii). Coronation is often combined with other rituals, such as enthronement (the throne is as much a symbol of monarchy as the crown) and anointing (again religious sanction, the only defining act in the Biblical tradition of Israel). In other cultures no crown is used in the equivalent of coronation, but the head may still be otherwise symbolically adorned, as a royal tikka in the Hindu tradition of India
