A Nawab of Dhaka pledged the Daria-i-Noor to the British in 1908, and Bangladesh has not opened the vault to see if it is still there

The Daria-i-Noor of Dhaka is a flat table-cut diamond, distinct from the Iranian stone of the same name. Ranjit Singh of the Punjab held it. When the British took the Punjab in 1849, the East India Company took it from the treasury of the boy Maharaja Duleep Singh and valued it at 63,000 rupees. It was shown at the Great Exhibition in London in 1851. In November 1852 Hamilton and Company auctioned it in Calcutta, and Khwaja Alimullah, founder of the Dhaka Nawab family, bought it for 75,000 rupees. In 1907 the Court of Wards took over the Nawab Estate. In 1908 Nawab Salimullah mortgaged the estate and the family treasures to the government. Court papers valued the diamond at 500,000 rupees and the 108 or 109 pieces at 1.8 million rupees. After Partition the treasure went to a bank in Dhaka and later to Sonali Bank. Inspections were reported until 1985^†. In 2025 the Land Reforms Board chairman said he had never seen the jewels. The government formed a committee to open the vault on 11 October 2025. On 9 October the opening was postponed without a stated reason, and no new date was set. The vault was still sealed when last reported.
