Gorrila Glass vs. Sapphire

                                     GORILLA GLASS vs. SAPPHIRE

Sapphire is much harder to scratch than Corning industry leading Gorilla Glass or Dragontrail Glass. From the manufacturing cost . It's about 10 times more expensive and 1.6 times heavier than glass. All it requires more energy to generate a Sapphire crystal than it does to generate glass. Productive  Sapphire of the same quantity as gorilla glass is nearly three times more expensive as it involves large furnaces and diamond to make it ready for the purpose. And after that cumbersome process, the output is a material which is 67 per cent heavier than Gorilla Glass and even less transparent.

Sapphire is harder not stronger and is less likely to get scratched. On the other hand, Gorilla Glass may survive a fall more often than a sapphire. Gorilla Glass transmits more light than sapphire thus implementing Sapphire means dimmer devices.
