One of the most important things that you can learn before you buy a diamond is it's "anatomy." These factors are critical measures in determining the quality of a diamond's cut.

Cut

Light entering the diamond reflects internally from facet to facet and is reflected back through the top only, creating maximum brilliance, scintillation and dispersion.*

Standard Cut Standard Cut
Most diamonds are “spread” in their cutting to retain maximum weight from the original rough. A heavier diamond will result, but with the sacrifice of fire and brilliance.
   
Too Deep Too Deep
When a diamond is cut too deep, light* leaks out of the bottom, brilliance is lost, and the center of the diamond will appear to be dark. This is called “Nailhead.”
   
Too Shallow Too Shallow
When a diamond is cut too shallow, light* leaks out of the bottom, brilliance is lost, and the diamond appears watery, glassy and dark. This is called “Fisheye”.
