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. Girdle Refers to the middle of the diamond that separates the crown , or top of the diamond from the pavilion , or bottom. 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.
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 octagonal outline when looking through the stone. The culet is graded through the table, with the stone face up, under 10X magnification. Polish The polish grading rates the surface of the diamond. This indicates how symmetrical and aligned the facets of the diamond are to one another.
