I hope none of you have forgotten the luxurious Aurora Diamante fountain pen. The diamond-studded pen was touted to be the most expensive in the world. Now, this exquisite pen studded with over 2000 diamonds, and a gold nib is finally available for sale for an astonishing sum of £900,000 ($1,470,600). The company makes only one such pen per year, and this exclusivity factor will surely play a big role in attracting buyers from across the world. Wonder who will finally be the proud owner of this luxurious pen. Any guesses?
