The Duchess Dazzles in Dolce and Diamonds

Diamonds—and rubies and gold—really are Fergie’s best friend.

The Black Eyed Peas frontwoman showed off a dazzling array of Cartier jewels during her joint birthday celebration with Quentin Tarantino last night in Las Vegas, with six different pieces that added up to being worth nearly $150,000!

Among the glamorous goodies were $52,100 white diamond and ruby earrings worn to the Mirage’s Jet nightclub, along with a matching $23,000 bracelet.

For the reception at the Bare Pool Lounge, Ms. Fergie slipped on a Dolce & Gabbana dress plus a Cartier Love diamond and ceramic bracelet worth $35,100 and a $23,100 necklace (above).

No word if the famed jewelry house let her keep any of the baubles.
