A jeweler once explained to me that old cut diamonds let light escape through the point of the diamond, while new cut diamonds reflect the light, making the diamond more brilliant. What looks like a hole is the area where the light passes out the back of the diamond instead of reflecting like the rest of the stone. This is not a physical hole.
