6. Nicole Kidman ($7 million)

At the 2008 Oscars, Nicole Kidman appeared as a flawless embodiment of beauty, as she wore a simple but glamorous LBD by Balenciaga. But what really made her ensemble stand out was her elaborate necklace by L’Wren Scott. It was studded with over 7,600 diamonds, and took 6,200 long and arduous hours, which sums up to 258 straight days, to complete the piece, custom-made for Kidman. The extravagant piece cost her a whopping $7 million, and it looked the part, as well.
