iPhone = Optical Glass or Sapphire, is what!?

My mother believes that her light sapphire, I think so because the videos ive seen people mutilate with a key and scratches in all, I have even tried to "handling" equipment and no scratches, sapphire is one of the most difficult with 10 diamonds, the hardest thing is the diamond can scratch or your car, so it is what sapphire optical crystal

Well, today is a high incidence of optical glass, but some of next versions may be of different materials, but perhaps Sapphire should be tested before being sold
