There is now a possibility that your phone screen could be made of manufactured sapphire. Sapphire, being the second hardest material on the planet, would be 3 times as strong as the usual phone screens but will be 10x as expensive. Most phone screens are Gorilla Glass, made by the company Corning, which is usually $3  for a screen. The new sapphire screens will cost around 30 dollars each, but are expected to drop to around $20. Apple's Iphone 5 already has manufactured sapphire for the screen over the camera.
