Diamonds in the Earth are much more common than we thought. About 1,000 times more common, according to the Massachusetts Institute of Technology.
A new study by an interdisciplinary team of researchers used seismic technology (the same kind used to measure earthquakes) to estimate that a quadrillion tons of diamonds lie deep below the Earth's surface.
Translation: 1,000,000,000,000,000 --- or one thousand times more than one trillion.
Don't expect a massive diamond rush, though. The deposits sit some 90 to 150 miles below the Earth's surface. That's deeper than current mining machinery allows.
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.

The diamonds that end up in necklaces and rings come closer to Earth's surface, usually through volcanic eruptions.
