I’ve been splashing cash on new mobile phones of late, and it got me thinking, what’s the most expensive phone out there for general purchase?

My Blackberry was about 3% of the cost of a new Vertu Ascent phone. It doesn’t leave much change from US $6,500. Alternatively, you could get the Vertu Signature Gold for $25,000. Just imagine leaving that thing on the bus (yes, I know, if you spent $25K on a phone you’re hardly likely to take public transport)

You get more than a phone (as well you should), you get 24 hour access to a personal concierge to help with lifestyle and travel assistance.

If you really think $25K is a bit beneath you and you’re worried you co-worker might purchase one too, you could always take the customisation route.

You could visit the Millionaire’s Fair at Cannes and pick up the “Piece Unique” for $1.2 million. The “Piece Unique” handmade phone is constructed out of solid gold, is studded with diamonds and comes with a customized insurance policy.

The phone is one of three that have been produced by Swiss company GoldVish. One of the phones has been bought by a businessman in Hong Kong, the other remains unsold. It also has 100 limited edition “Plato” phones, which are encrusted with 35-carat diamonds and have a US $244,000 price tag.
