Apple Is Getting into the Sapphire Business - What That Means

| Analysis

Apple is getting into the sapphire business—synthetic sapphire—by building a plant for a company called GT Advanced Technologies, Inc. The plant will be owned by Apple, but the equipment inside that plant will be owned and operated by GTAT in a multiyear deal financed by Apple to the tune of US$578 million.

Synthetically produced Sapphire is grown in a lab, but it has the same hardness as the naturally produced gemstones of the same name. That's 9 on the Mohs scale, and that means it's frakking hard.

Sapphire has been used for decades as "watch crystal" covers for watches, particularly high-end watches. Apple is currently using sapphire to cover the Touch ID sensor on iPhone 5s, but the size of the contract with GTAT makes it clear that Apple has big plans for sapphire in either its existing products...oh, who am I kidding? Think iWatch.

GTAT announced in a press release that it had entered into an unspecified "multiyear" agreement to supply Apple with sapphire material. GTAT said that it will repay Apple's $578 million loan over five years, but did not specify how long the supply contract itself will last. As noted above, Apple will build and own the plant—a separate expenditure not covered in the loan, which is for furnaces and other equipment.

This is the exactly the sort of thing Apple has been doing for years in Asia, where Apple either builds a plant and/or buys the equipment that is then operated by third party experts in the component industry. This allows Apple to maintain control over the products and the facility, while at the same time mitigating risk for the supplier.

By assuming that risk (in the form of paying for all the gear), Apple is also able to get even better prices on its components. This is all made possible by Apple's enormous cash hoard.

Apple has long acknowledged that it engages in these kinds of deals, but we don't usually get to see the details because they're happening off-shore. GTAT, being a publicly traded U.S. corporation, disclosed the deal in its quarterly earnings announcement.

Also, let me emphasize the fact that Apple is building this plant in the U.S. CEO Tim Cook has touted the fact that Apple has been bringing some manufacturing back to the U.S., and this another example of the company doing so.

On a more general basis, it's very interesting to see Apple make such a major investment in sapphire. As I said above, this simply has to be related to a new wearable product, most likely the much-rumored iWatch.

That said, Apple could also be expanding the use of sapphire in its existing product lines. Surely Touch ID will eventually make it to iPad and iPad mini, and Apple could even bring it the Mac line some day.

Now we can just sit back and wait for Samsung to announce that it also has a major investment in sapphire because it was way into sapphire before everyone else.

Building it in the USA, smart move.


Iphone displays? Stronger than gorilla glass…

I believe that Samsung invented sapphire, then patented methods to cut it into certain sizes and thicknesses.


Wonder what is the business motive behind having this in the US? Perhaps it’s easier to maintain secrecy and prevent leaks in the US.

Truffol it may be more for reliability of supply. Also perhaps quality control and security.

@sabo79, I was wondering about iPhone displays, too. Would Apple really sink that many millions into sapphire production solely for an untested product like the rumored iWatch? If so, they must be really confident that they have a soon-to-be best-seller in their R&D labs.

If they really are thinking about sapphire for iPhone displays, then the maximum diameter of the boules they grow becomes an issue, especially if they are thinking of a larger screen for iPhone 6. Also, while sapphire may be harder than Gorilla Glass, it might also be more brittle, and thus more likely to crack or shatter if dropped. Those factors—especially boule diameter—might rule out using sapphire for iPhone screens, leaving touch ID sensors and the rumored iWatch.


good to hear they’re bringing it back to the US. I’m frakkin tired of sending my cash to the middle east for oil and to china for my electronics…..
