The most expensive jewelry at the Oscars 2018

Our favorite stars shine like diamonds on the Oscars red carpet last night! From Chopard and Tiffany & Co to Harry Winston, the likes of Gal Gadot and Helen Mirren have made big statements with their precious jewelry.

We loved Nicole Kidman's sparkly earrings, which she pairs with her royal blue gown. With over 84 carats of diamonds between her cuts, we weren't surprised that she wore her hair sleek and swept behind her ears to show off that frost! The actress maintained her thrones and toes with the designer's designer diamond and platinum bracelet, Tulip Diamond Bracelet, Dream Brilliant Diamond Cluster Ring and Oval Shaped Diamond Band.

If Salma Hayek's stunning Gucci gown wasn't bright enough, she decked herself in some pretty cool jewels too! The actress has worn more than $4.2 million in Harry Winston diamonds, from her oval ring to her platinum earrings.

Jennifer Garner learned the fashion game at the Oscars! With her relaxed waves and bright blue dress. The actress went with Piaget to enhance her look, and her sapphire and sapphire diamond earrings total more than $600!

Oscar nominee Greta Gerwig stunned in a Tiffany & Co. moonstone necklace, designed by Louis Comfort in 1910. Among the jewelry collection, Greta's costume designer Christina Ehrlich commented, "The necklace we chose was the perfect blend of subtlety and statement." The crystal stones, which have been known to be good luck, are beautifully matched against the decor in her outfit. “

Superstar Allison Williams won perfectly manicured Hollywood waves to accentuate some of her dazzling jewelry. She wore over 26 carats of Harry Winston diamonds, through her diamond hoop earrings and cluster bracelet.

Another great talent representing Harry Winston was the amazing Helen Mirren. The actress grossed over $3.8 million in sapphires and diamonds, and she also shimmers in a platinum-set sapphires and diamonds. The icing on the cake was just the right look for a queen filling pair of gorgeous diamond rings.

Zoey Deutch was another talent showing great love for Tiffany & Co. last night! The actress wore a pair of Tiffany Collection color earrings from 2018, paired with a morganite ring and two diamond bands. Its total look at over $40000.
