The big selling point of sapphire glass is that the material is essentially unscratchable (unless you attack it with diamonds), and a company called Aero Gear wants to show that off what sapphire glass can do in the video below. It is a fairly basic test. An iPhone has been fitted with an Aero Gear sapphire glass screen protector, then it has a concrete block dragged over the surface. Of course, since the video is used to show off the Aero Gear screen protector, there is no damage found at the end.
The majority of the rumors around sapphire glass have come from the Apple mill. Word has it that Apple wants to expand the use of sapphire glass, which is already used as the home button cover on the iPhone 5s. The latest rumors say that the iPhone 6 will feature a full sapphire glass display. We've already seen Apple getting a patent for producing sapphire glass displays to be used in electronics; and, there has been talk that Apple is setting up a sapphire glass production facility in Mesa, Arizona.
