Crowning Achievements: The World's Most Beautiful Tiaras

Pearl Poiré Tiara (Denmark)
Queen Margrethe II has an impressive collection of headgear, and this pearl poiré tiara is among her finest. Made in 1825 as a wedding gift from King Friedrich Wilhelm III of Prussia to his daughter Louise, it consists of 18 pear-shaped pearls that dangle from diamond arches. Louise, Queen of the Netherlands, passed it on to her daughter Lousia, Queen of Sweden and Norway, who left it to Margrethe.
