It doesn't really matter that he can't see her face; he's known her long enough and been in bad enough situations with her that he can read it in her body language, probably just as well as she can see his impatience.

Once she has the necklace in hand, he starts moving again. "No," he replies. "I don't wear that kind of shit. Let's just get out of here."

This is something of an lie, because he has seven piercings and wears rings in the place of brass knuckles. In any case, once they're out of the building, he powerwalks as fast as he can without running to the car, only extending a hand for the diamonds so that she can drive.
