This royal diamond is a blue stone that is believed to have originated in India. It was once part of both the Bavarian and Austrian Crown Jewels.
But the diamond that exists today is markedly different to the blue stone that was once owned by royalty. It was substantially recut by Laurence Graff, who paid $16.4 million for it in 2008, in order to remove flaws from the stone.
Around three carats were removed from its size to achieve the aim, and the diamond is now 31.06 carats in size.
