Wikipedia

Faceting

In geometry, faceting (also spelled facetting) is the process of removing parts of a polygon, polyhedron or polytope, without creating any new vertices.

New edges of a faceted polyhedron may be created along face diagonals or internal space diagonals. A faceted polyhedron will have two faces on each edge and creates new polyhedra or compounds of polyhedra.

Faceting is the reciprocal or dual process to stellation. For every stellation of some convex polytope, there exists a dual faceting of the dual polytope.

Examples of use of FACETING
1. The trick with faceting diamonds is getting them to glitter.
2. For those on a tight diamond–budget, they have much smaller diamonds with the same Russian faceting.
3. In professional circles, it has come to be known as KR57 (from the word krugly –– "round"), and more commonly "Russian faceting." In nonprofessional circles –– that is, among people like us –– it‘s known as a blindingly sparkly diamond.
4. This involves a round stone with 57 facets (a "commercial" faceted stone has a paltry 33 facets). This is the faceting done by the 1,000 specialists at the Smolensk Kristall factory.
