The faces of a diamond are typically referred to as facets. The most common cut, the round brilliant, has 58 facets, including the table (the flat top), the crown (the upper portion), and the pavilion (the lower portion).

Each facet plays a crucial role in the diamond's brilliance and overall appearance.
