Vertu is a British company that manufactures and retails their luxury phones that start at $5,100 and head beyond $310,000. The phones, made of gold, sapphire (for the screens), ruby bearings and fine leather, come with a full year of free concierge service at the touch of a "hot key" on the phone.
I visited a Vertu boutique while in New York during Fashion Week this past summer. We went into the Plaza Hotel off 5th and they had a Vertu shop in the downstairs (along with free wine and chocolates, an art show, and models). Beyond the art deco inspired designs, the phones are top of the line and beautiful.
