The Darya-i-Nur, meaning ‘Sea of Light’, pale pink, weighing 175 to 195 carats (the mounting makes ascertaining an exact weight impossible), inscribed in Persian on one of the pavilion facets, ‘The Sultan, Shahib Qiram, Fath Ali Shah, Qajar 1250 ’. It was pillaged from Delhi in 1739 and is currently in the treasure vaults of the Central Bank of Iran in Tehran, having formed part of the Iranian Crown Jewels.
The Noor-ol-Ain, meaning ‘Light of the Eye’, pale pink, weighing approximately 60 carats, and like the Darya-i-Nur likely cut from the Great Table diamond in the second half of the 19th century. It is the central stone in this tiara, created by Harry Winston for the Empress Farah Pahlavi on the occasion of her wedding to Shah Mohammad Reza Pahlavi, in 1958. It is also currently in the treasure vaults of the Central Bank of Iran.
The Agra, named after the celebrated city of the Taj Mahal, it is first noted as having belonged to Mogul Emperor, Babur, in 1526.
