The Jewels of Farah Pahlavi, Empress of Iran
A beautiful demi-parure created by Van Cleef & Arpels for HIM The Shahbanou of Iran, which she wore on the evening of Coronation Day. The outstanding necklace consists of seven square yellow diamonds surrounded by old-cut diamonds from which hang seven pear shaped diamonds. With matching earrings.
The Iranian Imperial Family is known for having some of the more lavish jewels in the 20th century.
Sadly, when the family fled Iran in the 1970s, Farah left her jewels behind and now they are on display at National Treasury of Iran at the Central Bank in Tehran.
