When it comes to gadgets, many of us have to stay within the confines of our budget. But some techies can fulfill their caviar tastes for tech, wrapping them in precious metals and jewels. If you fall in the latter camp — or you wish you did — behold the most luxurious smartphones in the world. We’re talking iPhone 5s decked out in gold or snakeskin, a titanium Android phone and a BlackBerry designed by Porsche. You’ll even find a device made of a hybrid stone material for that chic marble look. Just bring money. Lots of money.
