The origin of the Black Diamond stone is quite controversial. 3 theories are possible and gemologists cannot agree on a common version.

The first theory says that the black diamond comes from an organic transformation of carbon. It is formed from the pressure of the Earth.

The second theory suggests that it would be the impact of a meteorite several million years ago that caused the deposits.

Finally, the last theory is about the explosion of a supernova. Its debris was scattered on Earth.
