A quadrillion tons of diamonds are hiding in the Earth

For those of you currently shopping for an engagement ring, here's some good news: There are a lot more diamonds hiding in the ground than we thought By measuring seismic waves rippling through Earth, scientists have discovered a quadrillion tons of diamonds about a hundred miles below the planet's surface That's as much as a thousand times more than previous estimates, National Geographic reported.

A quadrillion - which is about the number of ants that are alive worldwide, to give you some perspective - tons is still only a small percentage, as it turns out The newly discovered diamonds amount to only about 2 percent of the layer of Earth where they were found "It was unexpected," said Joshua Garber, the author of the study, "But not unprecedented" The rarity of diamonds has always been a little exaggerated by jewelry markets - and now, it's even more so.
