Please, watch this videos, you could see a very large window when the emerald is tilted from about 10° to 30° from observer.
Of course this is an approximation, because it depends om the observer, the tilt of emerald and the light source.
What makes me really distressed is that under some circumstances the window is larger than 50% of the stone!!!
What do you think?
