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.
