Koh-i-Noor: The History of the World's Most Infamous Diamond by William Dalrymple & Anita Anand

On 29 March 1849, the ten-year-old maharaja of the Punjab was ushered into the magnificent Mirrored Hall at the centre of the great fort in Lahore. There, in a public ceremony, the frightened but dignified child handed over great swathes of the richest country in India in a formal Act of Submission to a private corporation, the East India Company. He was also compelled to hand over to the British monarch, Queen Victoria, perhaps the single most valuable object on the subcontinent: the celebrated Koh-i-Noor diamond.

The Mountain of Light. The history of the Koh-i-Noor may have been one woven together from gossip of Delhi bazaars, but it was to become the accepted version. Only now is it finally challenged, freeing the diamond from the fog of mythology that has clung to it for so long.
