The Noor-ol-Ain is one of the largest pink diamonds (around 60 carat) 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 general Nader Shah Afshar looted and ransacked Delhi in the 18th century.
The Noor-ol-Ain is believed to have once formed part of an even larger gem. That larger diamond is thought to have been cut in two, with one section becoming the Noor-ol-Ain and the other the Darya-ye Noor diamond. Both of these pieces are currently part of the Iranian Crown Jewels.
