They've got the yacht, they've got the sports car, they've got the cryogenic freezing chamber and even a secret moon base. When money is not an option, what do you grab the billionaire who has it all?
A swarovski diamond encrusted smartphone of course! Why, yes! Fly in the face of fashion with these garishly garnished and stupendously expensive phones that not only make calls, but can also act as a down-payment on a reasonably sized mansion on the French Riviera.
Click below for our countdown of the world's ten most ridiculously expensive mobile phones.
10 – Bang and Olufsen Serene
In at ten is the actually rather stylish Bang and Olufsen Serene, priced at £675. I actually quite like the sleek number key ring, and the fact that this clamshell phone saves you the inconvenience have having open it yourself thanks to a little built in motor. You'll note however that the more expensive the phones get, the f'uglier they get too.
