The affect is the definitely the refraction of light through the crystal... in the Gen pics it appears the rehaut is thinner than is possible to clear the hand stack, which is obviously impossible. The thickness of the crystal and the index of refraction of the crystal are at play here... the rep crystal will not have the same index of refraction because it isn't the same type of sapphire... so the thickness has to be adjusted. I'd say try a couple different crystals... the one's they sell on ebay are very thick... just a thought.
