The saga surrounding Louis XIVs blue diamond is a web of intrigue, betrayal and a bizarre curse, spanning three centuries. First brought back from India, it was then stolen during the French Revolution. Later, in London, another diamond appeared - slightly smaller but equally magnificent - the Hope diamond. Is the Hope diamond a re-cut version of the mythical blue gem? Through the discovery of a lead replica of Louis XIVs stone, and the contribution of cutting-edge technology, a professor at Paris National Museum of Natural History, Francois Farges, leads a unique investigation up to it's final revelation.
