Digital Studios Whether you are hitting a viewing party or have a DVR date, get ready for major style-stalking: the stars strut down the Oscars red carpet on February 28 starting at 7:30 p.m. on ABC. Gear up with an exclusive look at the sparklers we’re still obsessing over from last year—every one is a winner. 01 of 07 Cate Blanchett in Tiffany & Co. Frazer Harrison/Getty Images; Time Inc. Digital Studios When you have a whopping 900 carats suspended from your neck, you don’t need much else to make an impact. With 500 carats of blue-green stones and aquamarine gems capped by diamond pins, this showstopping piece is designed to resemble the sun reflecting off the water. “The necklace is so stunning that it worked amazingly well with several dresses,” says Blanchett’s stylist, Elizabeth Stewart, who eventually chose to pair the masterpiece with an understated black column by Maison Margiela. “Cate fell in love with the Tiffany creation immediately. We considered it with a pink gown and then a purple one, but in the end, we opted for classic black,” says Stewart. “The simplicity of the dress allowed the necklace to be the focal point.” 02 of 07 Keira Knightley in Chanel Chris Pizzello/Invision/AP; Time Inc. Digital Studios Dressed in a bohemian floral Valentino Haute Couture number, with her hair twisted into loose waves, Knightley went for an outfit that was decidedly anti-Oscars. The actress, who was six months pregnant with daughter Edie, wanted to feel “free and fun,” says stylist Leith Clark. In fact, because the dress itself was unique, Knightley wasn’t really planning on wearing any jewelry at all—until Clark caught a glimpse of this 18kt rose gold and white gold ring encrusted with 205 brilliant-cut diamonds, pink sapphires, and carved pink opals. “The gown appears unstructured and delicate, but this ring is bold and strong, so it’s quite the opposite,” says Clark. “It almost looks as if it has superpowers." 03 of 07 Margot Robbie in Van Cleef & Arpels Frazer Harrison/Getty Images; Time Inc. Digital Studios The presenter banked the ultimate #TBT with a necklace originally designed for the Duchess of Windsor more than 70 years ago. “Everyone thought Margot had cut her blond locks, but she was wearing a fake bob,” says makeup artist Tyron Machhausen, who helped her primp to accentuate the vintage Zip Antique Colombine marvel made of an 18kt yellow gold zipper adorned with diamonds and sapphires. Machhausen coupled the faux chop with a fiery red-orange kisser. 04 of 07 Kerry Washington in Fred Leighton REUTERS /DANNY MOLOSHOK /LANDOV; Time Inc. Digital Studios When it’s time to weigh her accessories options, Washington turns to her most trusted— and arguably most adorable— adviser: her 22-month-old daughter. “Isabelle runs the show,” makeup artist Carola Gonzalez says jokingly. While the tot watched, Gonzalez used pastels to bring out the hues in the actress’s pink-toned sapphire and diamond earrings. “We knew that Kerry wanted to wear her hair back, so the earrings became the centerpiece of the look,” she says. “The stones were soft, elegant, and regal, just like her.” To play up the pastel tones of the platinum-set danglers, Gonzalez selected a pale pink pout for Washington, the global Neutrogena brand ambassador, though Gonzalez had an ulterior motive during the glamming process: “To try to get Kerry to spill some Scandal scoop!” 05 of 07 Julianne Moore in Chopard Christopher Polk/Getty Images; Time Inc. Digital Studios Cue the style envy: Not only did Moore snag a best actress statuette for her leading role in Still Alice, but she also wore a dress custom-made by Karl Lagerfeld for the occasion. “We wanted to strike a balance between her gown and the jewelry,” says stylist Leslie Fremar. “If she were to win, we wanted her to be rocking pieces that, years from now, wouldn’t seem dated in pictures.” Moore found her perfect match for the one-of-a-kind white Chanel Haute Couture column dress in these pear-shaped diamond dazzlers set in 18kt white gold. “You can’t appreciate their size from the photos,” says Fremar. “When you hold them, they take up the entire palm of your hand.” 06 of 07 Lupita Nyong’o in Chopard Ethan Miller/WireImage; Time Inc. Digital Studios How do you pick the perfect accessories when your stunning white Calvin Klein gown is embellished with pearls from top to bottom? If you’re Nyong’o, you choose classic jewels that complement the dress without competing. The actress and Oscar winner walked the red carpet clad in Chopard diamonds, including drop earrings featuring 18 carats of pear-shaped diamonds and 2.32 carats of rose-cut diamonds set in 18-kt white gold. She completed the look with a trio of sleek rings from Chopard’s Copacabana and High Jewelry collections: a cluster of briolette diamonds totaling 14.7 carats, a 3.57 carat cushion-cut diamond surrounded by pave diamonds, and a whopping 5.8 carat round cut diamond. 07 of 07 Gwyneth Paltrow in Anna Hu Jason Merritt/Getty Images; Time Inc. Digital Studios A dress as bold as Paltrow’s petal pink, floral-shouldered Ralph & Russo gown deserves jewels that make a statement just as big. The actress chose one-of-a-kind earrings from jeweler Anna Hu to complement her look. The dazzlers each featured two pear-shaped cabochon Rubellites weighing 101 carats and two pear-shaped Rubellites weighing 23 carats. Surrounding the precious gems? A blaze of white and yellow gold diamond that inspired the style’s name: the Fire Phoenix Earrings. To match, Paltrow donned the jewelers Petales D’Amour ring featuring a rare pigeon blood Burmese ruby.
