6. Diamond-studded Heavy Smartphone
Value: $15,000,000
Although it retains all the functions of a regular iPhone 5, this phone is crafted entirely from solid gold with 653 sparkling diamonds, especially a rare 27-carat black diamond embedded in the Home button. This is truly a work of digital art that makes everyone surprised. However, perhaps the use of the $15,000,000 to buy this phone can be replaced by investing in other useful items.
