(F) FACETED A faceted girdle consists of a small series of polished facets. Diamond cut in a way to include many facets. The multiple facets structure increases light reflection and gives the stone a bright and shining look.
(NF ) NON-FACETED Diamonds that do not have geometrically shaped flat polished facets are graded as non faceted
A diamond's culet is the point on the bottom of a diamond's pavilion. A diamond's culet may be pointed or it may be blunted with a small facet. The culet facet can vary in size. This culet's size determines the grade that the culet is assigned.
