Daria-i-Noor

[4] During the reign of Naser al-Din Shah, an elaborate frame was crafted from 457 smaller diamonds and four rubies, crowned by Iran's imperial insignia.

[8][2] Its early origins are shrouded in mystery, but it is believed to have been one of the eyes of the Mughal Peacock Throne.

[2]Eventually the diamond made its way into the hands of Maharaja Ranjit Singh of the Sikh Empire, where it was kept in the Toshakhana (treasury).

[2] A reference is made to it in a list prepared by John Login of confiscated items from the treasury.

[2] Thus, two years later it was shipped back to India to be auctioned off, with the Nawab of Dhaka being the winning bidder.

[2] In 1965, a Canadian team conducting research on the Iranian Crown Jewels concluded that the Daria-i-Noor may well have been part of a large pink diamond that had been studded in the throne of the Mughal emperor Shah Jahan, and had been described in the journal of the French jeweller Jean-Baptiste Tavernier in 1642, who called it the Great Table diamond ("Diamanta Grande Table").
