The Spirit of de Grisogono is the worlds largest cut black diamond and the fifth largest diamond in the world. The diamond had a rough weight of 587 carats and was mined some time ago in western Africa before being brought to Switzerland where it was cut using the traditional Mogul diamond cutting technique. De Grisogono then set the cut diamond (312.24 carats) into a white gold setting encrusted with 702 white diamonds (36.69 carats).
