But those covers are much smaller than a mobile phone and are two to three times thicker than Gorilla Glass. In one of our commonly accepted strength tests, sapphire breaks more easily than Gorilla Glass after the same simulated use. Additionally, sapphire’s cost and environmental hit are huge issues."
