Earth’s interior is dark, but filled with diamonds.
A study published Monday estimates the composition of deep rock layers known as cratons and concludes that they may be far more glittery than previously suspected. Parts of Earth’s mantle may be up to two percent diamond by composition, far more than previously suspected. In terms of sheer mass, that works out to around a quadrillion, or thousand trillion, tons of diamond.
