British jeweler Stuart Hughes, famous for his diamond-encrusted technology, announced an addition to his collection: An $8 million iPhone 4. Calling it the "most expensive phone," his website says the phone's bezel includes 500 flawless diamonds, which total more than 100 carats. The back of the phone is made from rose gold and includes an Apple logo fashioned from 53 additional diamonds. The limited edition had a run of only two phones. (Handout)
