Having just started using an ideal-scope, I have noticed that an apparent table light leak can occur by just altering the distance a fraction away from the lens. Similarly, you can seem to totally diminish this effect if the stone is held just within the scope?
I know the instructions say that you ideally (excuse the pun) should have the diamond flush with the plane of the scope opening. This is easy with a loose stone held with tweezers, it is much harder with a stone on one of those other dooverhickies where the stone is held end on or when it is mounted on the ring.
How susceptible are most diamonds to this effect? Since the presence or absence of a table leak is so critical to evaluation, I am a bit concerned that a small error on my part can totally change my assessment of a stone. How do I deal with this?
