“How impure can your sapphire be, and still call it sapphire?” That’s the question posed by YouTuber JerryRigEverything, who’s been testing the iPhone 7’s sapphire crystal -- or, rather, ‘sapphire crystal’ -- camera lens.
With the aid of an XRF machine and electron microscope, he’s found that it’s nowhere near as scratch-resistant as it should be, and believes this is due to Apple using a cheapo version tainted by contaminants such as carbon and silicon.
Apple prioritising profit margins over all else? Who would have thunk it?
A comparison of the iPhone 7 lens with a Tissot sapphire watch has worrying results. While the watch only scratches at level 8 on the Mohs scale of mineral hardness, the lens scratches at level 6 -- that’s what you’d expect from Gorilla Glass.
