Diamond Culet
The culet (pronounced kyoo-lit) of a diamond is the tiny point at the base of the pavilion, where the facets of the pavilion meet. In the majority of diamonds, the pavilion facets are uniformly cut at the proper angle and meet at a perfect point, yielding no culet (sometimes called a pointed culet). When the pavilion facets do not meet at a point, the culet is a rough or polished facet. The presence of a culet adds an additional facet to the diamond's total number of facets, while a pointed culet does not. For example, a brilliant round diamond with a faceted culet has 58 facets, while a diamond with a pointed culet has 57 facets.
