Discovered in a South African diamond mine in the early 20th century, the largest blue diamond ever found (over three carats) was destined for the crown of a British king but its journey as a royal gift was fraught with real danger. Coming so soon after the bloody war between Great Britain and the South African Republics, the public announcement of the stone's royal destination angered many white and black South Africans, and a secret decision was made to take up arms and prevent it from leaving South African soil. Paul C Venter's nail-biting thriller Emily's Smile is a new and terrifying adventure based on the great stone's final journey.
