Diamond nautilus armor is an upcoming type of nautilus armor that can be equipped by a nautilus that reduces the damage received to the nautilus. It is the second-strongest tier of nautilus armor, having higher armor points and armor toughness than golden nautilus armor. It can be upgraded into netherite nautilus armor using a netherite ingot and netherite upgrade at a smithing table.
