A flat surface on a geometric shape – a single cut plane of a gemstone. Many gemstones grow with naturally occurring facets. Where facets are created using a machine, the planes are carefully considered to for the overall cut. A brilliant cut diamond contains 57 or 58 facets in varying shapes, including table (the top of the stone), star (which surround the table) kite or crown, upper girdle, lower girdle, pavilion or arrow and culet – the tiny facet at the bottom of a diamond (that often appears as a point).
