This is a schematic “ball and stick” scale model of the mineral diamond developed using a combination of Pauling’s Rules, XRD-derived bond lengths, and simple trigonometry in CINEMA 4D by Hanna Wilson as part of the W&L GEOL 211 class (Earth Materials I: Rocks and Minerals). Her description of the structure follows: Diamond is composed of entirely carbon, shown in blue. In this structure you will see the carbon molecules shown at 50% in order to see the interior of the structure. I have included multiple tetrahedrally coordinated polyhedral elements (green) in order to see the way carbon arranges itself in diamond. The diamond structure can be seen by removing the green tetrahedral and observing the bonds (shown in pink). The entirety of the structure was made by copying tetrahedra and building downwards.
