The 98th Academy Awards had a new category, some old comedy routines, and a nail-biting lineup of blockbuster films competing for the top prizes—creating a major moment on Sunday for celebrity jewelry with big fancy diamonds, unusual colored gemstones, and revered jewelry designers like James de Givenchy getting their flowers on- and offstage.
The top Oscars were split between One Battle After Another, which won six awards including best picture, best director, and best adapted screenplay (both for Paul Thomas Anderson), and Sinners, which—much to the crowd’s delight—took home best actor for the sinfully talented Michael B. Jordan, plus three other prizes, including best original screenplay for director Ryan Coogler and best cinematography for Autumn Durald Arkapaw (that category’s first-ever female winner).
Best-dressed accolades for the night—and the whole awards season—go to One Battle’s Teyana Taylor, who wore a black-and-white Chanel gown embroidered with her children’s names and a suite of Tiffany & Co. diamond jewelry. She also wins best attitude, for her support of her fellow actors and her excitement over her film’s multiple victories.

Key trends from the Dolby Theatre included face-flattering chokers like One Battle costar Chase Infiniti’s De Beers London Metamorphosis Summer diamond necklace; elaborate earrings such as Demon Hunter Rei Ami in David Webb’s Sky Lantern earrings with emerald drops and fluted amethyst beads; and men’s brooches, with a sterling example from JCK fave Kieran Culkin: a two-piece Sauvereign brooch that was truly one of a kind with its hand-engraving and guilloché finishing.
Here are some of JCK’s favorite jewelry looks from the red carpet and Oscar stage.
Rose Byrne

Social media was ablaze with conversation around Byrne’s Oscar look. Nominated for best actress for her role in If I Had Legs I’d Kick You, Byrne wore a sculptural torque necklace from Taffin featuring a 22.58 ct. fancy yellow-brown pear-shape Desert Diamond and an Arizona Blue ceramic and 18k rose gold ring centering a 16.54 ct. fancy deep brown-yellow Ashoka-cut diamond sourced from Botswana.
In a statement, Taffin designer James de Givenchy said, “It’s always gratifying to see a piece leave the studio and take on a life of its own. Jewelry is meant to be worn and experienced, not simply kept in a case. I can’t imagine a more wonderful way to showcase it to the world than on a beautiful actress like Rose Byrne on the Oscars red carpet.”

Teyana Taylor

Every fashion follower had their eyes on Taylor, and, whew, she did not disappoint. Her stunning black-and-white gown was accessorized to perfection with her Tiffany & Co. jewelry, including a necklace in platinum with an 18+ ct. diamond drop, as well as earrings and rings in platinum with diamonds.

Demi Moore

From Brat Pack to awards-show fashion queen, Moore continues to impress. A nominee last year and a presenter this year, Moore wore a suite of Boucheron jewelry. Her pieces included the Vendôme Liseré sleepers, with blue emerald-cut tourmalines, diamonds, and black lacquer in white gold; the Vendôme Liseré ring, with a 4.13 ct. emerald-cut diamond, round diamonds, and black lacquer in white gold; the Vendôme Liseré bracelet with emerald–cut diamonds, round diamonds, and black lacquer in white gold; and the Ruban Diamants diamond and white gold transformable piece in a bracelet version, from the Histoire de Style, Art Déco high jewelry collection.

Arden Cho

In two historic wins, KPop Demon Hunters took the best animated feature and best original song Oscars. Cho—who voiced the hit film’s main character, Rumi—dazzled in exceptional Messika creations, including the Firebird necklace featuring 89 carats of diamonds with a stunning 5 ct. cushion-cut diamond. She also wore the brand’s Firebird earrings and a cushion-shape diamond ring.

Ava DuVernay

Director and producer DuVernay was a study in elegance wearing Pomellato’s Indicolite Blue high jewelry necklace, Indicolite Blue high jewelry earrings, and Catene ring.

Kristen Wiig

Wiig was a highlight of the Bridesmaids reunion onstage wearing Boucheron’s Quatre Classique necklace, set with brown PVD and diamonds on yellow, pink, and white gold; the Snake ring, with 19.16 cts. oval citrine in yellow gold; and the Quatre Classique XXL cuff with brown PVD and diamonds in yellow, pink, and white gold.

Ryan Destiny

Actress Destiny worked with stylist Law Roach to bring Marli New York high jewelry into the conversation. Destiny wore the Chance set, including a necklace with 16.05 cts. t.w. diamonds in 18k white gold, along with the matching ring and bracelet.

Molly Sims

Sims brought springtime sunshine to the Oscars with Rahaminov Diamonds, including a 18k yellow gold choker with a 30.29 ct. bezel-set fancy light yellow diamond, as well as 12.06 cts. t.w. bezel-set fancy yellow diamond earrings.

Nia Vardalos

Who saw all of Vardalos’ ice at the Oscars? Martin Katz, that’s who. The My Big Fat Greek Wedding star wore a suite of Katz creations, including Rain Diamond chandelier earrings in 18k white gold, an alexandrite and diamond Oval Paddle ring, white diamond and black diamond flexible rings, and a black-and-white diamond Champagne collection flexible ring.

Cara Delevingne at the After-Parties

Many celebrities change outfits and jewelry for the post-ceremony parties. Among them, we have to give a shout-out to Cara Delevingne, who wore a pair of exquisite pear-shape diamond earrings totaling 9.12 carats from Hassanzadeh high jewelry at the Vanity Fair event. Delevingne’s luminous diamond ensemble embodied Hassanzadeh’s legacy, uniting star power with a century-old tradition of extraordinary jewelry.
