In some circumstances, the carbon appears to have originated contained in the mantle of the Earth, so carbon that was already throughout the Earth. In different instances, there’s proof very curiously to advocate that the carbon might have originated close to the ground of the Earth.

The diamonds that we see on the surface are ones then which could be delivered to the ground by a very deep-seated volcanic eruption. It is a very particular kind of eruption, thought-about fairly violent, that occurred a really very long time ago in the Earth’s historical previous. Now we have not seen such eruptions in latest cases. That they had been possibly at a time when the earth was hotter, and that is almost certainly why these eruptions have been more deeply rooted. These eruptions then carried the already-shaped diamonds from the higher mantle to the surface of the Earth. When the eruption reached the ground it built up a mound of volcanic material that in the end cooled, and the diamonds are contained within that.

Many diamonds do not ever get to that time as a result of they just did not survive all these things that needed to have occurred.
