of the Imperial Treasury. However, in the early 20th century, the first Pahlavi Shah transferred ownership of the crown jewels to the state as part of a massive restructuring of the country's financial system. Later in the 1950s his son and successor, Mohammad Reza Pahlavi, decreed that the most spectacular of these items be put on public display at the Central Bank of Iran. Korea There have been a number of crown jewels present in Korea since ancient times, spanning from the ancient Gojoseon dynasty to the last Joseon dynasty. Most of the regalia of these kingdoms, however, have been lost at various points in time, due to the successive rise and fall of the Korean dynasties and the subsequent and frequent raiding of Korean royal tombs and palaces by both Korean and foreign armies. The surviving regalia derive mainly from the Silla, Gaya, Baekje and Joseon dynasties. The crowns of Silla are noted for their exquisite gold and jade workmanship, which resulted from the spread of goldsmithing technologies from Egypt and Mesopotamia to Korea via the Silk Road. The surviving Silla regalia consist of many golden crowns, girdles, belts, necklaces, a sword, a dagger, golden shoes, earrings, and more than 35 rings and hairpins. However, the Silla custom was that every king and queen had their own set of regalia, hence the regalia for each monarch was buried with them in their tombs, warranting the creation of many different regalia depending on personal preferences, contemporary fashion and available goldsmithing technology. The Baekje regalia are similar to the Silla regalia, but are even more arabesque and consist of magnificent girdles. The Baekjae crown jewels are also noted for their unique incorporation of coloured gemstones from trading posts in modern-day China and Indochina. The Joseon dynasty regalia consist of formal jewel-encrusted wigs for the queen and everyday crowns encrusted with various precious gems. During the period of the Great Korean Empire under Emperor Gojong, the imperial family commissioned many brooches, western-style diadems and tiaras to suit western-style clothes. Japan ("Three Sacred Treasures") consist of the Holy Sword Kusanagi (草薙剣), the Holy Jewel Yasakani no magatama (八尺瓊曲玉), and the Holy Mirror Yata no kagami (八咫鏡). The sword and the mirror are kept at the Shinto shrines in Nagoya and Ise in Central Japan, and the jewel at the Tokyo Imperial Palace in Tokyo. The enthronement ceremony is traditionally held in Kyoto. The
