years old. Diamond formation is not a fast or simple process. In addition to time, it also takes incredible heat, massive pressure, and carbon to produce diamonds. The rare conditions necessary to ...

It has been long believed that the basis of which diamonds form is coal. However, geologists have been disputing just how much of a role coal plays in the formation of these complex gemstones. So far ...

Diamonds are fascinating - as jewellery but also because of the extreme hardness of the material. How exactly this variant of carbon is formed deep underground and under extremely high pressures and ...

Geologists have studied tiny pockets of fluids trapped inside diamonds to get a better understanding of how old humanity’s favorite rocks might be. In doing so, they identified three distinct periods ...
