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!

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.
