I think the formula is like:
The fewer the current life compared to total life the better the chance to get a gem.

Intriguing. In that case, you should get a creature nearly dead, then give it a ring of regeneration so it never dies. Lots of gems!

I've currently got a lovely fetish farm where someone's holding the chalice. I take the fetishes off them a couple of turns before they die, then normally they recover to full health so they can be diseased again!
