WebCrystal faces develop along planes defined by the points in the lattice. In other words, all crystal faces must intersect atoms or molecules that make up the points. A face is more … WebCrystal systems are all the ways that rotational axes of symmetry can be combined and connected to a lattice. There are 7 crystal systems in 3D, which directly connect to 32 point groups when adding mirror planes and inversion. The 7 crystal systems are: Cubic, Hexagonal, Tetragonal, Trigonal, Orthorhombic, Monoclinic, Triclinic.

WebFacets, those "geometrically arranged, flat surfaces" that cover faceted gemstones, all play specific roles in a gem's optical performance. When expertly cut, facets not only create beautiful patterns on the gem, they also help it shine. Sometimes, literally.
