Top 10 All-Time Most Expensive Red Carpet Jewelry

7 Jessica Alba’s Diamond Necklace

Jessica Alba took a significant step back from the acting world in recent years, to be able to spend more time with her family and bring her lifestyle business to life. Alba enjoys the occasional red-carpet appearance, and she wowed photographers in 2013 when she walked the Oscars red carpet wearing a peach Oscar de la Renta dress.

Jessica wore a Harry Winston necklace, which was a stunning finishing touch. The stunning diamond necklace was an estimated $5.8 million and perfectly complemented her delicate neckline.
