The Noor-ul-Ain is a giant pink diamond which is mounted in a tiara of the same name currently in the possession of the Islamic Republic of Iran. It is believed that the Noor-ul-Ain diamond was once part of a vast Indian diamond named “the Great Table” which was embedded in the throne of the greatest Mughal emperor Shah Jahan, who ruled India in the middle of the seventeenth century. When the Mughal dynasty withered and came apart a century later, the Persian shah Nāder Shāh Afshār looted and ransacked Dehli. Evidence strongly suggests that the Shah took the Great Table diamond and it was subsequently cut into two giant pink diamonds which became part of the Iranian treasury.
In 1958, the diamond was selected to be made into a wedding tiara for Farah Pahlavi (who became empress of Iran when she was wed to Shah Mohammad Reza Pahlavi, the famous shah of Iran). The great American jeweler Harry Winston designed this ornate tiara.
