Back in March, an MIT report suggested that Apple and other smartphone manufacturers could potentially switch to sapphire crystal displays rather than the standard Gorilla Glass displays currently in use.

As it turns out, Apple has already experimented with sapphire screens. In an interview with Swiss news site Tages-Anzeiger [Google Translation], Vertu COO Perry Oosting revealed that Apple investigated the possibility of a sapphire display, recruiting an unspecified number of Vertu employees to work on the project.

Vertu is a British company that produces luxury cell phones, some with sapphire displays, and at least two former Vertu employees appear to have joined Apple in the last year.

According to Oosting, Apple ultimately shelved the sapphire project because the material is unsuitable for production in the numbers that Apple requires at the current point in time. Corning, the company that manufacturers Gorilla Glass 3 for Apple's displays, has also stated that sapphire is an inferior option for mobile displays.

The company believes that Gorilla Glass offers greater strength, lower weight, less energy cost in production, and lower pricing; all important features for mass manufactured products.

Though Apple may not have current plans to utilize sapphire displays, it has incorporated sapphire crystal into the iPhone, as a cover for the rear camera on the fifth generation iPhone. Rumors have suggested that sapphire may also be used as part of the home button in the iPhone 5S.

Interesting!

Not that it matters, but just for the sake of correctness... ;) Tages Anzeiger is a Swiss newspaper, not German.

I'm sure Apple tries just about everything. I wouldn't be surprised to find out they experimented with just about any substance.

Emphasis.

That could change in 9 months, or in 3 years, or never.

Yeah, I read it as Apple needs some time to invest in whoever's infrastructure before it can get going. They didn't put it on the camera lens because it was for fun.

I don't want my screen to look like that.

I don't even know why they'd show that. We're talking about synthetic sapphire. A shot of the 5's camera would be more appropriate.

I'm puzzled as to why they looked at this in the first place - compared to gorilla glass, it doesn't seem to have many advantages...

I'd love a sapphire crystal display and would be willing to pay a premium to get it.

It's what my Rolex uses and there's not a single scratch..

My Omega watch has Saphire Crystal and I have it for almost 20 years after a lot of abuse without a single scratch. Pretty amazing. Great material.

Wow I went a checked out those Vertu phones. Very impressive. Never new there were luxury cell phones. $1250 for a phone is a little crazy but they are very nicely designed.

probably, but i bet there are a lot more iphones out in the world than omega watches. and the iphone display has to do a lot more.

its one thing building a demo unit. totally another manufacturing tens of millions of units for sale at prices people will pay

It is not very likely that sapphire would be used for the home button, as a scratched one would still function. Scratches on the lens however do affect the camera function.

If the home button would include a fingerprint scanner it might well be useful.

They still go out of fashion though, scratched or not.
