Synonymous to Most Expensive tag, Amosu has once again lived up to its reputation and rolled out the world's most expensive Blackberry. Though their previous bespoken Blackberry Pearl Limited Diamond Edition sported a heavy price tag of $90,000, this latest diamond encrusted Blackberry grabs the honor of being the most expensive till date. Shaped out of solid 18 carat yellow gold and caked with 4,459 brilliant cut diamonds with a net weight of 28.43 carats, only three such Blackberry will be made. Obviously for all that glamour and glitz, this exclusive Amosu Blackberry flaunts a stunning £125,000 ($200,000) price tag too. The handset is personalized with buyer's name or company's logo. It also comes with a 24 hour global concierge service focused on 'accessing the inaccessible'. Since one of the three handsets is also bought by some rich dude from Middle East, only two such handsets are now available. Care to indulge yourself or the love of your life with this bejeweled Blackberry this Christmas? Then rush to grab the world most expensive Blackberry before you come across the Sold Out notification.
