I don't think it was from a process of the kindergarden that went wrong, pearl stated the the gems BECOME corrupt. This implies they were fine at one point. Amethyst was "undercooked" and she still turned out fine as well. and finally, all of the holes at the kindergarten were uniform which meant the gems knew what they were doing and they were doing it right for a long time.
