The massive 425-carat gem-quality diamond discovered in March at the Cullinan mine in South Africa has a new name and new owners. Petra Diamonds announced that it sold the D-color rough stone to Dubai-based Stargems Group and Belgium-based Choron for just under $15 million. Before it was sold, Petra named the gem "Legacy of the Cullinan Diamond Mine" to honor its connection to one of the world's oldest and most prolific sources of majestic diamonds.
