Yeah, and it doesn't cost you anything to look for a pebble. My wife's car had a pebble and I was amazed how polished the side against the rotor was! It looked like a tiny piece of a granite countertop.
Since you haven't heard it the last 10 times you drove it, maybe the stone ground itself down so small that it fell out. I wouldn't worry about it until it happens again. And if it does, drive in reverse for a while and see what happens. Then jack up the car and look for it. And while you're there you can check the wheel for any play.
