Which way to face quartz points?

I want to make an orgonite charging pad but cant figure out which direction to point the crystals. I know that the pointy side emits anions (good for you) while the other side emits cations (bad for you). It would seem logical to point crystals towards the center if the orgone energy emits from the center but then that will point the blunt cation side of the quartz outwards in all directions.
