This is probably the most expensive iPhone in the world, costing 15 million dollars for a gold casing set with diamonds. This iPhone 5 is possessed by a Chinese businessman who wishes to remain anonymous. This product was designed by Stuart Hughes who named it: iPhone 5 Black diamond.
The Chinese businessman is a Big fan of Apple, and he wanted to “customize” his iPhone 5 to make it more elegant. The casing of the mobile phone is decorated with a gold casing weighing 24 carats and 650 diamonds.
A relatively low cost version of iPhone 5 for $33,500 has also been proposed by the designer. The products of such type can be seen at the site.
