There is no shortage of insanely expensive gadgets and accessories for the wealthy geek that feels the need to show off. The catch is that some of the really expensive handsets — like the Vertu Signature — can show off how rich you are, but really don’t offer much in the way of cool features and usability.

What if you are one of the really rich types that wants a phone that actually works well — like the iPhone 3G — but the iPhone just isn’t expensive enough for you? You could go with the iPhone 3G and then swath it in the most expensive iPhone 3G accessory ever — the $15,000 Noreve Diamond Case.

For your $15K you get a leather case available in 15 different color choices. The expense of the case comes in the form of 272 diamonds that adorn the front of the case. The diamonds are each between 18 and 22 points and are VS1 quality and G color. The total diamond weight is 6.8 Karats.
