WebJul 7, 2024 · Crystal Structure. The crystal structure of a diamond is a face-centered cubic or FCC lattice. Each carbon atom joins four other carbon atoms in regular tetrahedrons (triangular prisms). Based on the cubic form and its highly symmetrical arrangement of atoms, diamond crystals can develop into several different shapes, known as 'crystal habits'. WebFace Centered Cubic This unit cell uses 14 atoms, eight of which are corner atoms (forming the cube) with the other six in the center of each of the faces. Since the face atoms are shared by two cubes, they only contribute three net atoms to the unit cell. These three atoms plus the one from the corners yield the observed four net atoms in the ...
