The £5million diamond-clad iPhone unveiled

The iPhone 4 is wrapped in 500 flawless cut diamonds, totaling 100 carats

The world’s most expensive mobile phone has been unveiled – an iPhone 4 wrapped in 500 flawless cut diamonds, totaling 100 carats and worth a jaw-dropping £5million.

It features two interchangeable diamonds that fit over the 'home' button - a single cut 7.4 carat pink diamond and a rare 8 carat single cut flawless diamond - which, together, are worth more than £4million.

The back of the phone is plated in rose gold and the Apple logo glitters with 53 diamonds.

British designer Stuart Hughes, was commissioned to make two of the bespoke handsets by a mega-rich Australian businessman.

Stuart, a phone jeweller since 2003, said: 'It was a fantastic challenge and I am really pleased with the end result. The phones look superb. Phones are so popular at the moment and this is the ultimate design.

'The diamonds are rare and difficult to source, stones like that usually have a very long history. It is amazing that someone is prepared to spend £5million on a phone. I doubt it will get used because it is worth so much money.’

The phones come with their own protection box made from a single 7kg block of granite in imperial pink with the inner lined with Nubuck top grain leather.

Father-of-two Stuart gold-plated his first mobile phone, a Nokia 8800, in 2003 and has since been making elaborate bespoke designs for customers in London, Marbella and Monaco.

His cheaper iPhone models - which retail between £1,800 and £22,000 - have been snapped up by showbiz royalty including Stefano Gabbana, of Dolce and Gabbana. Chanel designer Karl Lagerfeld is also a regular customer.
