MIT finds Quadrillion tonnes of diamond 100 miles beneath us
| — the oldest and most immovable sections of rock that lie beneath the center of most continental tectonic plates. Shaped like inverted mountains, cratons can stretch as deep as 200 miles through the Earth’s crust and into its mantle; geologists refer to their deepest sections as “roots.”
In the new study, scientists estimate that cratonic roots may contain 1 to 2 percent diamond. Considering the total volume of cratonic roots in the Earth,
| the team figures that about a quadrillion (1016) tons of diamond are scattered within these ancient rocks, 90 to 150 miles below the surface.
“This shows that diamond is not perhaps this exotic mineral, but on the [geological] scale of things, it’s relatively common,” says Ulrich Faul, a research scientist in MIT’s Department of Earth, Atmospheric, and Planetary Sciences. “We can’t get at them, but still, there is much more diamond there than we have ever thought before.”

| Not surprising. Diamonds are just heat-pressured carbon
| Wouldn't that fuck up the market? Since they're less valuable nowb(or should be?)
| Every kiss begins with kilometers of mining
| Who actually cares about diamonds? Only rich folk that have way an excess of money care about them
| Fuck the diamond market.

This is only partly true. Industry needs also diamonds, because it is a hard material for tools to treat steel and it is also pretty pure, which is useful for optical technology like lasers.

Also Diamonds could be used for long resting micro-mechanic parts.

| >>367850 Diamond dust can be made in a lab though. Tools that use then are usually made from artificial diamonds since they're much cheaper than buying real ones. Still, your point is valid.
| How many diamond swords is that
| There's a hell of a lot more than that in the asteroid belts

| here may be more than a quadrillion tons of diamond hidden in the Earth’s interior, according to a new study from MIT and other universities. But the new results are unlikely to set off a diamond rush. The scientists estimate the precious minerals are buried more than 100 miles below the surface, far deeper than any drilling expedition has ever reached.
The ultradeep cache may be scattered within cratonic roots
