It's journey began in 1905 when the world's largest rough diamond, the 3,106 carat Cullinan, was discovered in south africa's mine bearing the same name. The Cullinan mine is known as the main source of blue diamond.

Finished at 12.03 carats, sotheby's will now offer the cushion-cut diamond on November 11 at its Magnificnet jewels and noble jewels sale at Geneva. Estimated to bring in between $35 million and $55 million, it is expected to smash the current world record for a blue diamond.
