In the beginning diamonds came from India, nowhere else. And the greatest of those ancient stones cut a deep and bloody path across the history and legends of the country. The Koh-i-Noor, the Mountain of Light, has been fought over, cursed and occasionally lost. Seized by British agents eager to please the young Queen Victoria, it now lies in the Tower of London, its ownership still disputed. Kevin Rushby follows the trail of this great jewel on a journey that takes him to many fascinating corners of India and to the heart of Indian culture. Along the way he meets the dealers, smugglers and petty crooks who populate modern India's diamond trade, and finds that the depths of human greed and the heights of spiritual aspiration are both bound up in India's long association with diamonds.
