Fasett

Fasett is a term used in Norwegian and other Scandinavian languages to denote a facet—a flat surface on a geometric shape or a cut gemstone. The word derives from the French facette, from Late Latin facetta, a diminutive of facies meaning “face.” In gemology, a facet is one of the polished flat surfaces on a cut gemstone, such as a diamond. The arrangement and number of facets influence the stone’s brilliance and symmetry, as light entering the gemstone is reflected and refracted across the facets. In cut-gem design, facets are created by precise grinding and polishing; common arrangements are table, crown, and pavilion facets in diamonds or other transparent gems.

In geometry and crystallography, a facet is any planar surface bounding a polyhedron, or a crystallographic plane on a crystal. Facets are used to describe the shape of minerals and to model shapes in computer graphics and 3D design.

Figuratively, “facet” is used to refer to an aspect or dimension of something more complex, such as a problem having multiple facets that must be considered separately. The term is widely used across disciplines to discuss perspectives, features, or components of a larger whole.
