<p>We loved Nicole Kidman's flashy earrings, which she paired with her show-stopping royal-blue gown. With more than 84 carats worth of diamonds between her pieces, we're not surprised she wore her hair sleek and tucked behind her ears to show off that frosting! Keeping her décolletage bare, the actress lined her arms and fingers with the designer's Secret Cluster diamond and platinum bracelet, Tulip Diamond Bracelet, Round Brilliant Diamond Cluster ring and an Oval-Shaped Diamond Rock band.</p> <p>Photo: &copy; Getty Images
<p>If Salma Hayek's stunning Gucci gown wasn't bright enough, she decked herself out in some amazing jewels, too! The actress wore more than $4.2 million in Harry Winston diamonds, from her oval ring to her platinum earrings.</p> <p>Photo: &copy; Getty Images
Jennifer Garner nailed the fashion game at the Oscars! With her relaxed waves and gorgeous bright-blue gown, we're certainly giving her stylist an A+. The actress went with Piaget to amp up her look, her jaw-dropping diamond-and-blue sapphire earrings ringing it at more than $600,000! <p>Photo: &copy; Getty Images
Oscar nominee Greta Gerwig stunned in a vintage Tiffany & Co. moonstone necklace, which was designed by Louis Comfort in 1910. Of the jewelry choice, Greta's stylist Cristina Ehrlich commented, "The necklace we chose was a perfect mix of delicate and statement. The moonstones, which are known to be good luck, are matched beautifully against the beading in her dress." <p>Photo: &copy; Getty Images
