A poorly cut lab diamond will be dull or oddly proportioned, rendering all other qualities irrelevant. The GIA is a well-known and respected lab grading entity that issues lab diamond reports. While GIA grade is important, it is not the only factor to consider when determining Cut. Keep this in mind as you shop for lab diamonds, as approximately 55% of all GIA round lab diamonds listed on the internet are Excellent cuts. This indicates that there is a wide range of "excellence" within their grade level - ranging from truly stunning to mediocre.

To determine the cut quality of a lab diamond, make sure it is not cut too shallow or too deep. Incoming light strikes the pavilion at a low angle when a Round Brilliant is cut too shallow. The light then passes through the lab diamond and exits through the sides, without reflecting back to the eyes through the table. Because of the large amount of escaping light, the lab diamond lacks both brilliance and fire. If a lab diamond is cut too deeply, light will strike the pavilion at a sharper angle, causing it to reflect to another pavilion and exit through the bottom of the lab diamond rather than through the table. As a result, when a lab diamond is cut too deeply, it becomes dull rather than radiant.lab diamond cut vs light reflection
