Depth Percentage: This is the percentage measurement of how deep the diamond is in comparison to its width.  This affects the brilliance and the value of the diamond.

Dispersion: Dispersion is the effect that appears when the diamond is tilted and you see small flashes of color appear across the surface.  This is also called the fire of the diamond. This is not to be confused with a diamond’s natural color.

Finish: The finish is the result of the cutter’s skill when altering the diamonds natural appearance.  This is graded with its symmetry and polish.

Pave: This defines several small diamonds placed closely together to create a glistening diamond crust that covers an entire piece of jewelry and the metal under it.

Point: A point is the unit measurement of the weight of a diamond.  One point is one hundredth of a carat.
