1. Bradley Cooper
Rarely does one get the chance to own an Oscars-worthy watch or jewel, let alone one worn by a Best Lead Actor nominee. Making its red carpet debut via Bradley Cooper's wrist was an IWC Big Pilot's Watch, currently being sold by Sotheby's in a special charity auction. Proceeds from the timepiece, which features a one-of-a kind engraving for the ceremony, will benefit the Antoine de Saint-Exupéry Youth Foundation. The only thing that could make this purchase better? A personal letter from Cooper will accompany the watch.
2. Charlize Theron
The Dior Parfums ambassador paired her pastel gown by the French fashion house with a generous helping of Bulgari jewels, including the company’s iconic Serpenti design.
3. Regina King
Best Supporting Actress winner Regina King was radiant in custom Oscar de la Renta and diamonds by Chopard.
4. Lady Gaga
The A Star is Born actress can now add Oscar winner to her resume. Even as she delivered a jaw-dropping performance of “Shallow” alongside Bradley Cooper, we could not take our eyes off her Tiffany & Co. necklace, which featured the Tiffany Diamond, a 128.54-carat cushion-cut canary yellow diamond. First discovered in South Africa in 1877, this diamond was last worn publicly by Audrey Hepburn for a Breakfast at Tiffany's publicity shoot. Redesigned in 2012 to commemorate Tiffany & Co.’s 175 years of excellence in design, the necklace now features over 480 stones.
5. Rachel Weisz
The Favourite actress accessorized her Givenchy Couture ensemble with a striking Cartier headpiece from 1903.
6. Laura Dern
Laura Dern's Bordeaux ruched leather gown by Rodarte was the perfect canvas for the more than 115 carats worth of Harry Winston diamonds that she wore.
7. Laura Harrier
The BlacKkKlansman actress wore a Louis Vuitton gown by Nicolas Ghesquière with a Bulgari high jewelry gem-set necklace and bracelet.
8. Allison Janney
In a dramatic Pamella Roland gown, Allison Janney dazzled in jewels by Chopard, namely her necklace featuring 60 carats of heart-shaped rubies.
9. Maya Rudolph
“Not-host” Maya Rudolph was one of several stars to don colorful, one-of-a-kind earrings by Irene Neuwirth.
10. Sarah Paulson
Pink was the color of choice at the 2019 Oscars, and Sarah Paulson was one of the standouts in her Brandon Maxwell gown. Adding a touch of glamour to her look was Harry Winston's Guipure diamond necklace, paired with diamond studs, also by Winston.
11. Elaine Welteroth
Author, journalist and pre-Oscars co-host Elaine Welteroth wowed in a sky blue sequined gown by Greek designer Celia Kritharioti and deco diamond earrings by Hueb to match.

17. Angela Bassett
In her Reem Acra gown and Sutra jewels, Angela Bassett was a pretty-in-pink vision.
18. Marina de Tavira
Roma actress and nominee Marina de Tavira wore J. Mendel with Lorraine Schwartz statement earrings to the Oscars, which saw three wins for the history-making film.
19. Tonya Lewis Lee and Spike Lee
Although it's hard to top the originality of Spike Lee's accessories – custom Air Jordan 3s and Radio Raheem's "love" and "hate" rings, as seen in Do the Right Thing, – his wife, producer Tonya Lewis Lee, certainly rose to the occasion in diamond earrings and a drop necklace by Forevermark.
