The Treasury of National Jewels

The Iranian National Jewels, originally the Iranian Crown Jewels, include elaborate crowns, thirty tiaras, and numerous aigrettes, a dozen bejeweled swords and shields, a number of unset precious gems, numerous plates and other dining services cast in precious metals and encrusted with gems, and several other more unusual items collected or worn by the Persian monarchs from the 16th century and on. The collection is housed at the Treasury of National Jewels, situated inside the Central Bank of Iran on Tehran's Ferdowsi Street.
