New study suggests Earth's interior is filled with diamonds
Earth holds quadrillion tonnes of diamonds deep beneath its surface

The study's methodology is fascinating, but how can we be absolutely sure that there's a massive, hidden trove of diamond down there?
A new study from MIT suggests the interior of Earth is "filled with a quadrillion tons of diamonds". But it will be a while until diamonds are every girl's best friend: the lavish gems are located so deep, no drill in existence can reach them.
They found our planet is likely to be composed of as much as 2% of diamonds by volume.
Although the MIT team estimates a quadrillion tons (or 1,000,000,000,000,000) worth of diamonds is in the cratonic roots, it makes up only about one to two percent of the rock's composition.
Faul's co-authors include scientists from the University of California at Santa Barbara, the Paris Institute of Geophysics, the University of California at Berkeley, the Paris Polytechnic Institute, the Carnegie Institution of Washington, Harvard University, and the University of Science and Technology. Craton is denser and denser than the occult around the planets, and produces sounds that are quite fast.
Thanks to this method, the scientists managed to notice an unusual behavior of the sound waves while passing through the cratons - they sped up more than it was expected.

‘Increased cancer risk for diabetics’ Overall, the researchers found women with diabetes are 6% more likely to develop any form of cancer than men with diabetes. Women in the studies were particularly at greater risk of developing leukaemia, cancers of the stomach, mouth and kidney.
Faul said the location of the diamonds at the base of the cratons makes the most sense, as diamonds are formed via extreme pressure and extreme heat, so the weight from all the rock above provides ideal conditions for their formation deep in the Earth's mantle.
So they assembled virtual rocks, made from various combinations of minerals, to calculate how fast sound waves would travel through them.
Researchers presently trust the Earth's antiquated underground shakes contain no less than 1,000 times more jewel than beforehand anticipated.
"One of its unique properties is, the sound speed in precious stone is more than twice as quick as in the prevailing mineral in upper mantle rocks, olivine".
But if they are over 100 miles below the Earth's surface, how did scientists find them? At the very bottom of these cratons lie the diamond "roots".
These pipes are often found at the end of cratonic roots - roots being the deepest section - in Canada, Siberia, Australia and South Africa, further confirming the theory at cratonic roots are in part made of diamond. "From all angles, we have experienced all the different possibilities, and this is the only possibility to leave a reasonable explanation".
