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.
