The optical anisotropy of polycrystalline graphite layers formed after catalytic graphitization of single‐crystal diamond surfaces has been studied as a function of crystallographic substrate orientation. It was found that the shapes and orientations of the two‐dimensional indicatrices of the graphite coatings were in complete agreement with the two‐dimensional point‐group symmetry of the underlying diamond surfaces. This means the graphite crystallites have one or more preferential orientations imposed by the substrate.
