It's OK, Corning (NYSE:GLW) investors; your Gorilla Glass should be safe for now. 

At least, that's what the Fool's Steve Symington argues in the video below, even as rumors swirl saying Apple's (NASDAQ:AAPL) iPhone 6 could feature a sapphire display and/or back panel when it's released later this year. But why?

First, Steve notes many recent headlines surrounding the topic are misleading, notably including those that refer to concept designs "based on leaked schematics" as their premise for confirming sapphire's extended role in Apple's iPhone 6.

In addition, he says investors should keep in mind that when sapphire supplier GT Advanced Technologies (NASDAQOTH:GTATQ) announced its deal with Apple in November, the terms were clear: While the agreement does require GTAT to maintain a minimum level of capacity, it does not guarantee production volumes.

Finally, GT Advanced Technologies also confirmed in late February it was still building out its new production facility in Arizona. This means GTAT would likely be hard-pressed to fill the massive quantities required to meet Apple's iPhone 6 demands, especially if the iPhone 6's rumored launch this Fall proves accurate.

To hear Steve's full take on what this means for investors in Apple, Corning, and GT Advanced Technologies, please watch the video below.

There's another massive trend brewing in Silicon Valley
In the video, Steve also mentions another compelling technology in which GT Advanced Technology's sapphire could be put to work. If you thought the iPod, the iPhone, and the iPad were amazing, just wait until you see this. One hundred of Apple's top engineers are busy building one in a secret lab. And an ABI Research report predicts 485 million of them could be sold during the next decade.
