When you are purchasing jewelry, do you look for the most beautiful or a worst looking piece? As a Graduate Gemologist, cut of a diamond is something I am passionate about! A quality cut can make your diamond sparkle from across the room no matter the size.

Oftentimes, people confuse the outside shape of a diamond with the Cut. The outside shape of a diamond is what we refer to as round, oval, cushion, pear, marquise, etc. But, Cut refers to the arrangement and balance of facets in a diamond.

The Gemological Institute of America (GIA) has five Cut grades for a round brilliant diamond: Excellent (EX); Very Good (VG); Good (G); Fair (F); Poor (P). The reason that Cut is so important is because it’s the reason a diamond will sparkle beautifully or be dull, it’s the fuel for the scintillation! We often assume that all diamonds shine, but it is not the case. As you can see with the range of cut grades, there is a variance of cut which translates to a variance of liveliness to dim!

When light enters a diamond, it bounces around internally and comes back out of the diamond. In a well-cut diamond, the light will come back out of the top to hit your eye so that you see the sparkle. In a poor cut diamond, the light will come out the sides leaving you to see a diamond that is dull with shadows.

In the picture above, you can see the affect the quality of cut has on a diamond. There are large shadows in the middle and right diamond, while the far left has so much life.
