Facets can be broken down into: Crown Facets and Pavilion Facets. The Table and Culet are also considered facets. The girdle of a stone can be faceted. The purpose of facets is to enhance the brilliance and scintillation of a gemstone.
Crown Facets
Table Facet
The often large, horizontally orientated, central facet of a gemstone’s crown which provides a window into the gemstone is called the Table Facet.
Star Facet
Main Facet
The Main Facets, or simply ‘mains’ which are also known as ‘Kite Facets’ lie in between the star and bezel facets.
Bezel Facet
Bezel facets, also known as the upper girdle facets, are the triangular facets which border on the girdle of a cut gemstone.
Pavilion Facets
The pavilion of a faceted gem can be divided into Main facets and Bezel Facets just as with the crown. On the image on the right the Bezel Facets, or lower girdle facets, are the light colored ones and the Main Facets the darker colored ones.
Furthermore, the pavilion harbors the culet, which in old cuts often consisted of a facet as well but has become a point in more recent times.
