WebDiamond has a crystallographic and cubic structure. The crystal form of diamond is an FCC or face-centred lattice. A lattice is an organised set of points that define the structure of crystal-forming particles. There are three types of lattice structures- face-centred (FCC), body-centred (BCC) and hexagonal closest packed (HCP).
