A video published this week showed an iPhone 7 with what appeared to be a scratched lens cover glass. This would be astounding, given the idea that Apple did indeed make this lens cover glass with Sapphire, a material that should only be able to be scratched with a diamond. In reality, the lens cover glass (which is indeed made of Sapphire) was not scratched, but fractured. Fracturing a piece of Sapphire glass at this size is possible, and easy, if one uses the right tools. In the real world, though, it's nearly impossible.
