About Natural Fancy Black Diamonds

Natural fancy black diamonds, also known as Carbonado, are real polycrystalline diamonds that can be found in their rough form in alluvial deposits in the Central African Republic and Brazil. They are different from other rough diamonds in that they are more porous, making them more challenging to cut, and may have high luminescence. Like all diamonds, they originate high pressure on carbon under the Earth's surface that produces a repeating geometric pattern in the crystal lattice. However, the black color, when it occurs naturally, it thought to be produced by the inclusion of graphite in the crystalline structure during formation, before the kimberlite deposits reached the Earth's surface. Carbonado was first used to polish wood in the Brazilian deciduous forest, and was transported to Europe after its use, although it was not set into jewelry at that time. It is also interesting to note that in 1905, black diamond was used for rock drilling in the Panama Canal.

Black diamonds do not sparkle like other colors - however, they look magnificent when paired together or set in a solitaire setting. Since they are completely opaque, they do not vary in intensity or color at all, and can only be found as Fancy Black. Truly natural fancy black diamonds are very rare and expensive, therefore most of the Black diamond are heated in Rough and that takes the price down dramatically.

There is also a theory that black diamonds are of extraterrestrial origin, unlike every other color of diamond which were formed at the Earth's core. A team of U.S. geologists, led by Stephen Haggerty and Jozsef Garai of Florida International University have published evidence claiming interstellar space as these diamonds' origin. They have found that black diamonds contain trace elements of nitrogen and hydrogen, which they postulate are sure indicators of an extraterrestrial origin!


Famous Black Diamonds



Black Orlov


Black Orlov is a 67.50 carat, cushion-cut diamond. The Black Orlov is currently set in a diamond brooch surrounded by 108 white diamonds and suspended from a 124-diamond necklace. 

Legend has it that the Black Orlov, also known as the "Eye of Brahma" was an uncut black stone of 195 carats, pried out of the eye of the statute of the sacred Hindu God Brahma, from a temple in Southern India. It takes much from the story surrounding the legendary Hope diamond. 

Apparently the stolen diamond found its way to Russia, where it is believed to have been acquired by Princess Nadia Vyegin Orlov of Russia – hence its name. In 1932, the diamond found its way to the United States. It was purchased in 1947 by Charles F Winson who sold it to an unknown buyer in 1969 for USD300,000.

  Spirit of de Grisigono 


The old Moghul-cut, 312.24 carat (587 carats rough), black Spirit of de Grisogono diamond is the largest black diamond in the world. It was mined in the Central African Republic but further details of the diamond are not known. 

The rough stone was purchased by famous Swiss jeweler, Fawaz Gruosi and cut by the world renowned black diamond cutting specialist, de Grisogono; after who it is named. The team of Gruosi and de Grisogono have been responsible for creating the current enthusiasm for black diamond jewelry. 

Planning of the cutting and the actual cutting process took over one year. The stone has been mounted on a white gold ring and set with 702 white diamonds totaling 36.69 carats.



The heart-shaped, 115.34 carat (300.12 carats in the rough) black Gruosi diamond took three years to be cut and polished because of the difficulties encountered due to the inconsistency in the hardness of the rough stone. The diamond was discovered in India in 1998 and was cut by the world renowned black diamond cutting specialist, de Grisogono. 

It is named after renowned Swiss jewelry and watch designer, manufacturer and dealer, Fawaz Gruosi. Gruosi is almost single-handedly responsible for bringing black diamonds to the prominence they have attained.

The Gruosi is the centerpiece of a magnificent necklace designed by Fawaz Gruosi. The necklace also consists of 58.77 carats of small black diamonds, 378 carats of small white diamonds, and 14.10 carats of tsavorite garnets, all set in white gold.
