Light leakages act as ''windows'' in a diamond, where you are seeing
through it. Areas of light leakages would not have any brightness, fire or
scintillation.
In black lit ASETs, the light leakages are revealed in the black areas,
which shows the black background. However, black lit ASETs can be very
misleading as it is able to camouflage a diamond's light leakages or
weak light return. An accurate and honest representation is to use a
white (non-black) lit ASET analysis.
