Tiara

In modern times, however, a tiara is generally a semi-circular or circular band, often metal, and decorated with jewels, which is worn as a form of adornment. It is worn by women around their head or on the forehead as a circlet on very formal or high social occasions. Tiaras are frequently used to "crown" the winners of beauty pageants. In western countries, a bride often wears a tiara as part of her bridal gown.

Queen Elizabeth II is said to have the largest and most valuable collection of tiaras in the world, many of which are heirlooms of the British Royal Family. She is often seen wearing them on state occasions. Her personal collection of tiaras is considered to be priceless. She received many of them through inheritance, especially from Queen Alexandra, and gifts from foreign countries. For example, a diamond and aquamarine tiara she received was a present from the people of Brazil.
