Yup, you read the headline correctly, and no, the figure mentioned there isn't in Zimbabwean dollars. The world's most expensive smartphone does cost over $16.5 million and it is a unique, hand-crafted piece of bling. What you see pictured is the iPhone 5 Black Diamond edition by Stuart Hughes. If you're wondering where the luxury handset got its name from, just take a look at its home button. The key has been replaced with a 26-carat flawless black deep cut diamond. This, however, is just one of the hundreds of gems covering the phone's surface.
The chassis of this fabulous iPhone 5 has been inlaid with about 600 flawless white diamonds and 53 more of them have been used to recreate the Apple logo on the back. Speaking of the back, that's a full gold outfit you see and a piece of solid gold is used for the logo's foundation. As for the screen, it boasts a layer of sapphire glass that's more resistant to damage than the scratch resistant glasses commonly used in modern smartphones.
All this gold and the precious stones have taken a toll on the phone's weight, however. Just the gold that has been put into the device tips the scales at 135 grams, which is 23 grams more than what the iPhone 5 originally weighs. Nevertheless, something tells us that the phone's owner wouldn't be bothered by its weight. Speaking of which, the iPhone 5 Black Diamond is owned by a Chinese businessman.
