Amosu Ultimo Diamond

The Amosu Ultimo Diamond is touted to be the most expensive iPhone in the world, retailing for a whopping $177,300. This high price tag is a reality no thanks to the 1,179 diamonds encrusted all over, weighing 16.18 carats. Since you're already forking out such a huge amount of dough for it, each purchase will come with access to the international all-day VIP-service Concierge (VIP International Concierge Service) for a year. After that, you can slowly peel off those diamonds and think up of 1,179 ways to propose to your girlfriend.
