No form has been shown yet of an ultimate diamondhead and it is unknown if one will ever be shown. We could say though that instead of diamondhead being made of crystal he'd instead be made of real diamond or taydenite as an ultimate version in which he'd be almost impossible to kill with that level of toughness.
