FACT:

The distance from the bottom of the girdle to the culet is the pavilion depth. A pavilion depth that’s too shallow or too deep will allow light to escape through the sides or the bottom of the stone. A well-cut diamond will direct more light through the crown.

Cut

GIA provides a cut quality grade for standard round brilliant diamonds that fall within the the GIA D-to-Z color range.

A polished diamond’s beauty lies in its complex relationship with light: how light strikes the surface, how much enters the diamond, and how, and in what form light returns to the eye.

The result is a magnificent display of three attributes: brightness (the total white light reflecting from the surface and interior of a diamond), fire (the dispersion of light into the colors of the spectrum), and scintillation (the flashes of light, or sparkle, when a diamond is moved).
