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). * http://www.sybarites.org/2006/07/26/spirit-of-de-grisogono-the-worlds-largest-black-diamond/ As far as Emeralds, there are several that are famous, here's just one:

The Duke of Devonshire, a highly included, deep green hexagonal prism of 5 cm in diameter and 6 cm in height weighing 1,383.95 carats, is one of the most famous emeralds in the world. This uncut crystal from Muzo, Colombia, was given to the sixth Duke of Devonshire by Emperor Don Pedro in 1831.
