The Noor-ul-Ain (Persian: نور العين,‎‎ “the light of the eye”) is one of the largest pink diamonds in the world, and the centre piece of the tiara of the same name.


The diamond is believed to have been recovered from the Golconda mines in India and was brought into the Iranian Imperial collection after Persian king Nader Shah Afshar looted Delhi in the 18th century.

The Noor-ul-Ain is believed to have once formed part of an even larger gem called the Great Table diamond. That larger diamond is thought to have been cut in two, with one section becoming the Noor-ul-Ain and the other the Daria-i-Noor diamond. Both of these pieces are currently part of the Iranian Crown Jewels.[1]

History of the tiara[edit]

The Noor-ul-Ain is the principal diamond mounted in a tiara of the same name made for Iranian Empress Farah Pahlavi's wedding to Shah Mohammad Reza Pahlavi in 1958. The tiara was designed by Harry Winston. It is a modern design, featuring 324 pink, yellow, and white diamonds set in platinum. It is said to weigh around 2kg. The tiara forms part of the Iranian crown jewels, held at the National Treasury of Iran in the Central Bank in Tehran.[2]

It is a Type IIa diamond.[3]
