iPhone 5S gets glitzy? Sapphire home button, gold option

Gold and sapphire. No, we're not talking about Rolex wristwatches but the iPhone 5S. All rumors of course.
The iPhone 5 already has a sapphire lens cover. But the 5S will get a convex sapphire home button too, according to KGI Securities' Ming-Chi Kuo (via 9to5Mac).
The reason? Sapphire prevents the button from being scratched and a slightly convex shape creates room for the fingerprint sensor, according to the analyst.
Note that there has also been speculation that the 5S' touch display would handle fingerprint sensing chores.
