    Following Apple’s adoption of sapphire crystal as a strong and durable covering for the rear cameras on the iPhone 5 and fifth-generation iPod Touch last year, rumors of expanded uses for the material have gained some traction. Amid the discussions of the potential of sapphire, Corning published a feature outlining why its latest Gorilla Glass 3 is in fact already a better option than sapphire for mobile device displays, citing greater strength, lighter weight, less energy cost in production, and significantly lower pricing. The features are the reason why Gorilla Glass has seen widespread adoption, with Corning reporting that over 1.5 billion devices have been made with Gorilla Glass. According to the feature:

    Jeffrey W. Evenson, [Corning] senior vice president, remarked, “Discussion seems to center around sapphire as an obvious solution for a cover material. What would people say if someone invented a cover that was about half the weight, used 99 percent less energy to make, provided brighter displays, and cost less than a tenth of sapphire? I think they’d say that sapphire was in real trouble. It so happens that we at Corning already invented that cover – and it’s called Gorilla Glass.” Evenson added that the company’s tests so far indicate Gorilla Glass requires about three times more force to break than sapphire after both materials have received similar wear and tear.
    Corning also discusses its latest work with Gorilla Glass, noting that the company has already trimmed the materials thickness to the point where it can be curved and shaped without losing any strength. Going even further, Corning lays outs its future plans for Gorilla Glass, sharing that the company is currently working hard on newer versions that reduce reflections for better visibility in bright sunlight and which incorporate antimicrobial technology to minimize the gems which are prevalent on mobile devices.

    How does Corning know the Sapphire production and energy costs? Most likely it is a complete guess. When they quote a 99% reduction it makes me think they are delusional or have no math skills - either way a major credibility hit.
    It's worth mentioning that the Gorilla Glass 3 didn't come out until this year so the iPhone 5 could not have used it. Samsung also chose a cheaper glass for the Galaxy Nexus.

    So why would Apple go with Sapphire over Gorilla Glass or did I miss something here??

    Gorilla glass 3 is new, and apple doesn't use sapphire, it used gorilla glass 2. Sapphire is used for the back camera hole only.

    Didn't Corning fail to mention the main reason for using Sapphire? It's much more scratch resistant than Gorilla Glass. That's why it was used for the camera lens.
