A bandeau is an ornamental headband or type of tiara. They were particularly popular during the Middle Ages in Italy and in Europe c.1825-1835. Bandeau in the Georgian Era were often composed of strands of gems or pearls that were neatly passed across the forehead and fastened into the coiffure in the back. Early fortification of the jewels with ribbon soon gave way to sturdier structures rendered in metal and more “tiara-like.”

During the Art Deco period, they enjoyed a return to the spotlight and bounce intermittently in and out of vogue on into the 21st century.
