Natural fancy black diamonds are polycrystalline diamonds unlike other white and colored diamonds which are single crystals. They are a conjoined mass of a multitude of tiny black diamond crystals. Also known as Carbonado Diamonds, these diamonds are usually pea sized or slightly larger.

Black Diamond is the toughest form of natural diamond. It is an impure form of polycrystalline diamond consisting of diamond, graphite, and amorphous carbon.,/p.

Stephen Hofer, a renowned gemologist, says that black diamonds are in “a transitional carbon state between graphite and pure diamond.” He further says that, “The typical black diamond is composed of a mishmash of atoms rather than a regular, homogenous arrangement.

We have only recently delved into the cause of color in black diamonds. The color comes from copious clouds of minuscule mineral inclusions like graphite, hematite or pyrite. These inclusions pervade throughout the stone. In addition, these diamonds are heavily fractured. The cleavages are stained black or turn black due to graphitization. The saturation of such internal features induce the coloration. By and large, natural color black diamonds are wholly opaque. They display a metal like high luster.

Black Diamonds Origin Theories

There are different theories regarding how the black diamonds came into existence.

One theory proposes that like all diamonds, black diamonds too formed in the high temperature/high pressure environment deep in the womb of earth. Like all diamonds, repeating geometric pattern is created in the crystal lattice of black diamonds under these extreme conditions. Tiny diamond crystals join together to form a black diamond as we see it.

Another theory suggests that black diamonds were formed by the shock transformation caused by a meteorite striking the earth’s surface.

Yet another theory states that black diamonds formed as a result of the radiation emitted by spontaneous fission of Uranium & thorium in nature.

One more exotic and fascinating theory suggests an extra terrestrial origin of black diamonds. Stephen Haggerty, a geoscientist from Florida International University, says that the source of black diamonds was an earlier-generation giant star.

The star exploded into a supernova around 3.8 billion years ago. The remains of the supernova drifted through outer space for millions of years. A large mass of it fell as a meteorite to earth which was a single land mass at the time before the drifting of continents. The meteorite probably fragmented while passing through earth’s atmosphere.

The impacted region of earth subsequently split into Brazil & the Central African Republic. Today, these two regions are the only known locations of carbonado deposits.

Earlier, Carbonado was used to polish wood in the Brazilian deciduous forest. Interestingly, Black diamond had been used for rock drilling in the Panama Canal. It was also extensively put to industrial use as cutting stone for long. Black diamonds were not set into jewelry at the time.
