Description:

The basic building blocks of carbon put under extreme pressure will arrange themselves into a material we call diamond, depicted in the left figure. The right figure shows how the carbon building blocks (represented by tiny black spheres) are arranged to form diamond. The lines between the spheres represent the bonds that hold the carbon together.
