Last week discovered an authentic-looking glass front panel of the upcoming iPhone 6 procured by Sony Dickson. In the past, this has already managed to obtain some components of iPhones and iPads, which, for example, revealed the existence of a plastic iPhone 5c or a gold 5s. He handed the panel over to well-known YouTuber Marques Brownlee, who tested the panel against rough handling, including stabbing. He therefore came to the opinion that it is probably a sapphire display, which, according to the video, was also claimed by a British expert on this material.

Despite this, we remained skeptical with the fact that it is not entirely clear from the video whether it is indeed a sapphire. Brownlee was also skeptical and subjected the panel to a second test, this time with sandpaper. Sandpaper can really test the hardness of a given material. On the Mohs scale of hardness, sapphire (corundum) is the second highest after diamond, which means that only diamond is able to scratch sapphire. Gorilla Glass, meanwhile, scores around 6,8 out of 10. The sandpaper Brownlee used was equivalent to a 7 on the scale, and it soon became clear that it wasn't actually sapphire as it left scratches on the panel.

Compared to the iPhone 5s, which was also subjected to the durability test, the scratches were significantly less obvious. On the contrary, the sapphire glass that covers the Touch ID remained intact. So the result is that the alleged iPhone 6 panel is significantly more scratch-resistant than the iPhone 5s panel, but it's not sapphire glass. Brownlee suggests that it could still be a hybrid material made up of artificial sapphire that Apple kept patent last year, but it is more likely that this is the third generation of Gorilla Glass.

So what will Apple do with its sapphire production and pre-ordered material for more than half a billion dollars to do? Apart from making Touch ID cover glasses and camera lens covers, where Apple already uses sapphire, the best offering is for the iWatch or similar wrist-worn device.
