Loaned for exhibit by Anonymous.

This large, fancy vivid blue diamond was displayed together with The De Beers Millennium Star at London’s millennium celebrations. As with the Hope Diamond, the blue color comes from boron atoms trapped in the crystal structure.

From the Premier Mine in South Africa, the Heart of Eternity weighs 27.64 carats.
