The crown is the upper part of a cut gemstone, which lies above the girdle. The crown consists of a table facet surrounded by either star and bezel facets (on round diamonds and most fancy cuts) or concentric rows of facets reaching from the table to the girdle (on emerald cuts and other step cuts). The crown facets both catch the light and reflect it back at the viewer. This effect is what ultimately gives the stone its brilliance. The amount of fire and brilliance are mostly dependent on crown and pavilion angle.
