Rose tried to heal / tame them, maybe she was able to fix the crack with her tears but wasn't able to fix the inner corruption. Gems take the physical shape of who they are and what they're like (personality, actions,beliefs & driven...); It is possible that a gem if lived in the corrupted state for too long ends up in the change of it's personality (bit by bit) also changing the outside aspect, then when the gem gets "healed" it only fixes the crack not the persona. I believe that is why those gems appear as monsters, that new appereance seems to "fit" better with their new personality.
