The Spirit of de Grisogono
Continuing our list of the largest black diamonds in history is The Spirit of de Grisogono, cut from 587 carats. It is the largest cut black diamond in the world, ranking 5th among the largest diamonds in the world.
The Spirit of de Grisogono was mined in the western part of Central Africa. To this day, none of the black diamonds can compare to the Spirit of de Grisogono in terms of purity and beauty. It was acquired by the Swiss jeweler Fawaz Gruosi, who was involved in cutting three out of the five famous black diamonds. He transported the crystal to Switzerland and cut the black diamond Spirit of de Grisogono to 312.24 carats in the form of a rose with a modern twist. This ancient cut, developed in India and known since ancient times, can be seen in other famous historical diamonds. Currently, the Spirit of de Grisogono diamond is set in the highest quality white gold and surrounded by 702 small white diamonds with a total weight of 36.69 carats. For over a year, Fawaz Gruosi studied the black diamond Spirit of de Grisogono before giving it this magnificent form, complementing the ancient rose cut with a modern design style. The black diamond Spirit of de Grisogono is described in the scientific work of the Gem Gubelin laboratory as a rare diamond specimen considering its color, quality, and large size. It has been in several private collections, but the jewelry company De Grisogono still owns the ring with the Spirit of de Grisogono diamond.
Gruosi
The black diamond called Gruosi was found in India in 1998. The Black Diamond Gruosi initially weighed 300.12 carats. Almost immediately after its discovery, this rare black crystal was bought by Fawaz Gruosi. The famous jeweler and watchmaker of the de Grisogono house had been studying black diamonds for many years. Cutting the black diamond into the Gruosi diamond proved to be difficult. Working with black diamonds requires skill and caution, as they are fragile in some areas and excessively hard in others. The cutting of this black diamond Gruosi was carried out in the Belgian city of Antwerp and took a whole three years. It was decided to give the black diamond Gruosi the shape of a heart. As a result of the processing, the Gruosi diamond lost more than half of its initial weight and turned into a black diamond Gruosi weighing 115.34 carats. Today, the black diamond Gruosi is set in a necklace of white gold and is accompanied by small black diamonds with a total weight of 58.77 carats, small white diamonds with a total weight of 378 carats, as well as garnets weighing 14.10 carats.
