New Tests Question Purity of 'Sapphire' in iPhone 7 Camera Lens

By Aatif Sulleyman on at

“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.

So, how impure can your sapphire be, and still call it sapphire? I wouldn’t hold my breath for an answer from Tim Cook and co. [YouTube via Verge]
