With gold price hitting record high anything gold seems to be a good investment. And how about the Apple iPhone set in a 22K solid gold casing with 136 diamonds in the front bezel and 53 flawless diamonds making up the rear logo and the navigation button created from a single 7.1 carat diamond.

This world's most expensive iPhone designed by British designer Stuart Hughes has been commissioned by an anonymous businessman for “only” $3.2 million. The phone comes in a special chest made from a single block of Granite, in Kashmir gold with the inner lined with Nubuck top grain leather and weights 7kg.

Huges spent 10 months creating the phone but apparently it was worth it.
