This $7.3 million 25 carat green diamond is a cushion-cut stone which is believed to have originated in South Africa. The stone is said to be the finest modern example of a green diamond.

The stone was put up for sale by Swiss jeweller de Grisogono in 2006 as part of a white gold ring with seven black diamonds.

The stone was owned by Fawaz Gruosi who is believed to have purchased it from a diamond dealer in 1998.
