Where do black diamonds come from?
White diamonds are mostly found in igneous rock, which was brought to the surface of the earth by volcanic activity. In contrast the black diamond, is found in alluvial deposits only in Brazil and the Central African Republic, as opposed the relative wide distribution of the white diamond.
The limited distribution of the black diamond makes it in effect much rarer than the white diamond, yet the most alluring aspect of the black diamond may be the mystery surrounding its origins.

There are various theories hypothesized as to the beginnings of the black diamond. These include:
- Formation within a star which exploded within a supernova and rained down onto earth billions of years ago by means of meteorites.
- Shock metamorphism subsequent to meteorites impacting earth.
- Creation upon impact on earth by an asteroid, as is the case with certain normal diamonds.
- Radiation via fission of uranium and thorium.

The most popular theories favour the extra-terrestrial alternatives as a result of the differences in structure and composition of these two types of diamonds coupled with the fact that evidence suggest that the only two known locations where black diamonds are found were once joined, before they were separated via continental drift. This supports the theories of either localised meteor showers in this area or a massive asteroid impacting earth.
