You can buy an iPhone 6 from Apple anodized with matte gold coloring. It's a nice enough phone, but it's no luxury.
That gold iPhone costs no more than one in silver or space gray, and it does nothing else different. Apple also makes a solid gold Apple Watch. It costs much more than a standard aluminum or steel Apple Watch. The Apple Watch Edition has a nicer buying experience and improved customer support (not that Apple's ever been lacking in that department). But even at up to $17,000 it too does nothing that a $350 Apple Watch Sport doesn't do.
