Most diamonds found on the earth’s surface were actually born well, well below’s the earth’s dusty crust (known as the “upper mantle,” like that shelf your parents displayed your “12th Place Gymnastics” trophy on). We’re talking roughly one hundred miles below, in a part of the earth that is very hot, and under intense pressure – like Adriana Lima in the Victoria’s Secret Angels Runway Show. Way down there, with the crushing force of tons of layers of rocks mingling with the inferno-esque heat, is where adorable baby diamonds are first born. Aww. This is of course scientific conjecture, as we don’t have the capability of actually sticking our heads down there and witnessing this.
