This article dives into the details of Sydney Sweeney’s extravagant Emmy Awards 2025 jewelry, exploring the craftsmanship, carat weight, and the buzz it created on social media platforms like X.

Sydney Sweeney’s Red Carpet Glamour: A Show-Stopping Look

Sydney Sweeney, known for her roles in Euphoria and The White Lotus, made a grand entrance at the Emmys 2025 in a custom Oscar de la Renta gown. The strapless, cleavage-baring red dress accentuated her hourglass figure, with gathered detailing around the bust and a floor-length skirt that trailed elegantly behind her. However, it was her jewelry that truly elevated her look to iconic status. Adorned with 175 carats of Lorraine Schwartz diamonds, Sweeney’s ensemble included a tennis necklace, pear-shaped diamond earrings, and massive diamond rings that exuded luxury and sophistication.

The actress, aged 28, has been a red-carpet favorite, consistently delivering bold fashion choices. Her appearance at the Emmys 2025 followed a successful stint at the Toronto Film Festival, where she premiered her Christy Martin biopic to critical acclaim. Sweeney’s ability to pair high-fashion gowns with statement jewelry has solidified her as a style icon, and her Emmys look was no exception. The Lorraine Schwartz pieces, known for their exquisite craftsmanship, perfectly complemented her glamorous aesthetic, making her one of the best-dressed stars of the night.

The Massive Marquise Diamond: A Painfully Stunning Centerpiece

The centerpiece of Sydney Sweeney’s jewelry ensemble was a 120-carat diamond tennis necklace, featuring a 40-carat marquise diamond drop that sparkled under the Emmy Awards’ lights. Jewelry influencer Julia Chafe, in a viral Instagram post on September 15, 2025, humorously described the marquise diamond as so massive it could “bruise you when you wear it.” While exact carat weights for each diamond in the necklace were not confirmed, Chafe speculated that the individual diamonds could be around 3 carats each, contributing to the necklace’s overwhelming brilliance.

Lorraine Schwartz, a renowned jewelry designer favored by celebrities like Beyoncé and Kim Kardashian, is known for creating bold, statement-making pieces. The tennis necklace worn by Sweeney was a testament to Schwartz’s expertise, combining classic elegance with modern extravagance. The marquise diamond, with its elongated, pointed shape, added a dramatic flair to the necklace, making it a focal point of Sweeney’s look. Social media platforms, particularly X, buzzed with reactions, with hashtags like #SydneySweeneyEmmys2025 and #LorraineSchwartz trending as fans and fashion enthusiasts dissected her jewelry choices.

Why the Tennis Necklace Stole the Spotlight

Tennis necklaces, characterized by a continuous line of diamonds, have long been a staple in luxury jewelry. Sydney Sweeney’s version, however, took this classic design to new heights. The necklace’s 120-carat total weight, combined with the 40-carat marquise drop, created a striking visual effect that was impossible to ignore. According to jewelry experts, the term “tennis necklace” originated in 1987 when tennis star Chris Evert paused a match to retrieve a diamond bracelet that had fallen off, bringing attention to the style. Sweeney’s necklace, with its massive diamonds, redefined this timeless piece for a new generation.

The craftsmanship of Lorraine Schwartz’s designs is unparalleled, with each diamond meticulously selected for its clarity and brilliance. The tennis necklace’s design ensured that every movement Sweeney made on the red carpet caught the light, creating a dazzling display. Fans on X praised the necklace’s bold design, with many calling it a “game-changer” in red-carpet jewelry. The combination of the necklace’s weight and sparkle made it a perfect match for Sweeney’s glamorous persona, cementing her status as a fashion trailblazer.

Completing the Look: Earrings and Rings That Dazzled

In addition to the tennis necklace, Sydney Sweeney wore 30-carat pear-shaped diamond drop earrings and 25 carats of diamond rings, further enhancing her radiant appearance. Julia Chafe, in her Instagram commentary, described the earrings as “the largest pear-shaped diamond earrings I’ve ever seen,” humorously noting their potential to cause discomfort due to their size. The rings, worn on both hands, were equally impressive, with Chafe joking that Sweeney needed two rings to maintain balance due to their substantial weight.

The pear-shaped earrings, with their elegant teardrop design, complemented the marquise diamond in the necklace, creating a cohesive and harmonious look. The rings, featuring large, sparkling diamonds, added an extra layer of opulence, ensuring that every angle of Sweeney’s ensemble was picture-perfect. These pieces, all crafted by Lorraine Schwartz, showcased the designer’s ability to blend boldness with elegance, making them ideal for a high-profile event like the Emmys.

Social Media Buzz and Industry Reactions
