The Spirit of de Grisogono, at 312.24
carats, is the world's largest cut black diamond (Black Diamonds are the rarest
diamonds that ever existed), and world's 5th largest diamond.
When it was discovered the Spirit of de Grisogono
weighted 587 carats (117g), and it is considered to be the largest natural
black diamond ever found.
 
The Spirit of de Grisogono was mined several
decades ago in west Central Africa before being imported into Switzerland.
It was then cut using the Mogul diamond cutting technique. This historic
cutting method was developed centuries ago in India and can be seen in a number
of historic diamonds.
There are not many black stones in the world of famous diamonds,
mainly the Black Orlov and the Amsterdam Diamond, which
weigh 67 and 33 carats respectively, and several diamonds in the Crown Jewels
of Iran, among them the Taj-I-Mah Diamond. The
Great Mogul, a 279-carat diamond, is another famous Mogul cut diamond, but
its whereabouts are unknown. The more modern rose cut is a variation on the
old Mogul cut. A 205-carat black diamond called the 'Black Star of Africa' is
rumored to exist, being sold to a buyer in Asia during the 1980's, but this has never been
substantiated.
The entire process from studying the cut design to executing it on the
de Grisogono rough involved more than a year's
work. The man behind this fascinating work is famous Swiss jeweler de
Grisogono. He was the first major jeweler to create eye-catching collections
of black diamond jewelry and watches. He is also responsible for cutting the
Gruosi Diamond, the largest heart-shaped black diamond in the world. The
diamond weighs 312.24 carats.

After the cutting was completed, De Grisogono
then set the 312.24 carats diamond into a ring made of white gold. The Spirit
of de Grisogono Diamond is surrounded by 702 white
diamonds weighing 36.69 carats.
The Spirit of de Grisogono Diamond ring was
sold to a private client by Fawaz Gruosi, the
icon jeweler and famous diamond cutter who leads
the de Grisogono House of jewellery, for an
undisclosed amount.
