The brilliance in a diamond is determined by the way the light reflects inside the diamond and is very dependent on the cut of the diamond.

The better the cut the more fire & brilliance. Diamond brilliance is defined as the reflection of a bright white light from the facets of the diamond and is determined by the artistry of the cutting and polishing. Each facet must be cut and shaped with precision, and placed with perfect symmetry.

A well cut diamond is referred to as ideal, excellent, or very good. In a well cut diamond the light enters at the top and forms a U shape and then exits back out at the top. With a deep cut the light enters from the top and forms an L shape as it exits out the side.

With a shallow cut diamond the light enters from the top and curves slightly back out at the bottom of the diamond. Too deep of cut or too shallow both interfere with the correct light reflection.

Of all the aspects that are important when purchasing a diamond, the brilliance is by far the most important as it is what gives your diamond life.

You may have a diamond with superior coloring, or it may be a very large diamond but if it isn't cut for maximum brilliance then what you have is a dull lifeless stone.

There are some terrific online resources for helping you understand what to look for before purchasing that diamond. Just remember brilliance equals beauty!
