A diamond or other gem of the finest cut, formed into faces and facets, so as to reflect and refract the light, by which it is rendered more brilliant. It has at the middle, or top, a principal face, called the table, which is surrounded by a number of sloping facets forming a bizet; below, it has a small face or collet, parallel to the table, connected with the girdle by a pavilion of elongated facets. It is thus distinguished from the rose diamond, which is entirely covered with facets on the surface, and is flat below.
Cut is the common style of diamond cutting. The standard brilliant cut consists of 32 facets plus a table above the girdle and 24 facets plus a culet below the girdle. Other shapes besides round can be faceted as brilliant cuts, including oval, radiant, pear or heart.
