Tiara

A tiara (from Latin tiara, from Ancient Greek τιάρα tiára) is a head ornament adorned with jewels. Its origins date back to ancient Persia, from where it was later popularized by the Greco-Roman world. By the 18th century, the tiara had become fashionable in Europe as prestigious pieces of jewelry worn by women on formal occasions. The basic shape of the modern tiara is a semicircular base, usually made of gold, silver, or platinum, and richly decorated with gemstones, pearls, or cameos.

Tiaras were extremely popular during the late 19th century and were worn at events with a white tie dress code. After World War I, their use declined, except for official occasions at royal courts. Interest in tiaras has increased again since the early 21st century. The word tiara is often used interchangeably with diadem.
