The Daria-i-Noor (Persian: دریای نور which means "Sea of light" in Persian; (also spelled Darya-ye Noor) is one of the largest cut diamonds in the world, weighing an estimated 182 carats (36 g). Its colour, pale pink, is one of the rarest to be found in diamonds.
In 1739, Nader Shah of Iran invaded Northern India, occupied Delhi and then massacred many of its inhabitants. As payment for returning the crown of India to the Mughal emperor, Muhammad, he took possession of the entire fabled treasury of the Mughals, including the Darya-i-noor, in addition to the Koh-i-noor and the Peacock throne.
Daria-i-noor, along with the Koh-i-noor, was later acquired by Ranjit Singh of Sikh Empire. It finally came into the possession of East India Company when Punjab fell under the British Rule in 1849. Daria-i-noor was one of the main attractions of The Great Exhibition in 1851. In 1852, Hamilton and Company auctioned the diamond under the direction of the British government. At the auction, the diamond was purchased by Khwaja Alimullah from Dhaka Nawab Family. In his visit to Calcutta in 1887, Viceroy of India Lord Dufferin went to see the diamond at Baliganj.
Daria-i-noor was also seen by King George V and Queen Mary during their visit to Calcutta in 1912. After the Partition of India in 1947, the diamond was transferred from Calcutta to Dhaka and since then, has been kept in in a vault of Sonali Bank. In 1985, a group of experts approved the genuineness of the diamond through an examination.
In 1965, a Canadian team conducting research on the Iranian Crown Jewels concluded that the Darya-ye 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"). This diamond may have been cut into two pieces; the larger part is the Darya-ye Noor; the smaller part is believed to be the 60 carats (12 g) Noor-ol-Ein diamond, presently studded in a tiara also in the Iranian Imperial collection (5).
