8.The De Grisogono Green Diamond – Price:$7.3 million
There’s only one rival for this one in the world.
The De Grisogono Green Diamond is the center piece of a spectacular white gold ring and is surrounded by other 7 karats of sparkling black diamonds.
This is a 25-karat pale green diamond that is extremely rare with only one rival in the rest of the world.
The De Grisogono Green Diamond can only be compared to the 41-karat Dresden Green diamond that is displayed at the Dresden Castle in Germany.
Our cushion-cut beauty was sold by the jewelry house De Grisogono in December 2006 for the fantastic sum of $7.3 million!
