Preheat oven with pizza stone to 525 degrees.
Sprinkle pizza peel with cornmeal; carefully transfer pizza round to peel. Top round with an even layer of mozzarella pieces, then top with layer of Gorgonzola. Sprinkle pizza stone with cornmeal and slide pizza onto hot stone. Bake 6 minutes. Remove pizza from oven, let cool 2 to 3 minutes, then drizzle on olive oil and season to taste with pepper. For a softer crust, dab rim with a moistened brush after first 3 minutes of baking.
