Earth Has More Diamonds than Previously Thought

There may be a quadrillion tons of diamonds under the Earth’s surface, according to a study conducted by an international team of scientists and published in the journal Geochemistry, Geophysics, Geosystems.


But don’t get your hopes up on mining them: According to the study, the deposits are located in “cratonic roots” between 90 and 150 miles below the Earth’s surface (much further than any drill has gone).

“This shows that diamond is not perhaps this exotic mineral, but on the (geological) scale of things, it’s relatively common,” Ulrich Faul, a co-author of the study and research scientist in MIT’s Department of Earth, Atmospheric, and Planetary Sciences, told MIT News. “We can’t get at them, but still, there is much more diamond there than we have ever thought before.”
