Cut

How a Diamond Handles Light

It is the precision and delicacy of the cut that dictates the maximum amount of light that will be reflected through the diamond.

When a diamond is cut to good proportions light is reflected from one facet to another and then dispersed through the crown or the top of the stone.

If the cut of the diamond is too deep some light escapes through the opposite side of the pavilion or bottom.

If the cut is too shallow light escapes through the pavilion or bottom before it can be reflected.
