This relationship is an indicator of the diamond's brilliance. In fancy shapes, the total depth and other proportions are not scrutinized the same way as round brilliants. The table is the largest facet of the diamond and considered the window. Again, in fancy shapes, the table diameter and other proportions are not scrutinized in the same way as in round brilliants. This can vary depending on how thin or thick the girdle actually is.
Some girdles are faceted and others are granular and have a frosted appearance.
Culet - The culet is a polished facet placed at the tip of the diamond to prevent chipping. The culet ranges from none or white abraded to extremely large, which would show an octanganal outline when looking through the stone. The culet is graded through the table, with the stone face up, under 10X magnification. Polish and symmetry are given the grades of Excellent, Very Good, Good, Fair, and Poor. Almost all diamonds have inclusions, though most are not discernable to the eye without aid of magnification.
