Huge, rare diamonds help us learn more about the Earth's mantle



Metal treed in diamonds up to 10 carats provides young insight into Earth’s geologic evolution . (https://www.researchgate.net/blog/post/4951)

Large stone diamonds like the Cullinan own a set of physical characteristics that distinguish them from other kinds of diamonds . (https://www.eurekalert.org/pub_releases/2016-12/gioa-lrd120716.php)

They tell that these bigger and rare diamonds have a different story to tell than their smaller counterparts . (http://topexaminer.com/2016/12/19/big-diamonds-tell-a-story-about-the-earths-complex-geology/)

Previous experiments and possibility own predicted for many years that parts of the deep mantle below about 250 km depth contain small amounts of metallic fe and own limited available oxygen2 . (https://www.gia.edu/diamonds-reveal-inner-workings-of-earths-mantle)

The most convincing grounds that coal did not drama a role in the formation of most diamonds is a comparison between the mature of Earth's diamonds and the mature of the earliest land plants . (http://geology.com/articles/diamonds-from-coal/)

And so by moving speedily they fundamentally got secured into place into the diamond structure . (http://www.smithsonianmag.com/science-nature/diamonds-unearthed-141629226/)

"Ride on a rocketA wild volcanic eruption called a kimberlite quickly carried this particular diamond from deep in the mantle . (http://www.livescience.com/44057-diamond-inclusions-mantle-water-earth.html)
