The world's most expensive iPhone has been unveiled – with a price tag of £1.92- million.

The pricey phone, made by Stuart Hughes, a designer from Liverpool, took ten months to make and was ordered by an Australian man, Britain's Telegraph reported.

Hughes said that the most time-consuming task was sourcing the diamond to be used as the main navigation button. According to The Times Online, the casing is made up of 22 carat solid gold. The phone's face is made up of 136 diamonds while the Apple logo on the back is composed of 58 of the precious gems.

Of course, you wouldn't want to store this phone in a simple leather or Velcro-sealed pouch, and it's for that reason that the phone comes with a leather- lined granite chest, according to IT Wire.
