Analyzing the Goniometry of Sculptures on the Faces of Natural Diamond Crystals

The data on the goniometric study of the most common sculptures on the surface of natural diamond crystals are summarized. These sculptures consist of flat microplanes, which appear during the growth or dissolution of diamond crystals. They are a component of their surface and take an immediate part in the creation or destruction of diamond crystal faces. The results of goniometry for trigonal and ditrigonal hatchings on octahedron edges, straight- and inverse-parallel triangular and hexagonal pits on octahedron faces, quadrangular pits on cube faces, and drop-shaped hillocks and caverns on rounded dodecahedron faces are considered. It is shown that the most common microplanes of sculptures crystallographically correspond to the simple crystal forms, which often have large symbols and form clusters generally around the most important diamond structure forms.
