While the plunging black gown became the main subject of online debate, Sánchez’s jewelry attracted almost as much attention.
The centerpiece was a dramatic diamond necklace that sat prominently around her neck. The extraordinary piece was reportedly estimated to be worth as much as $10 million.
Jewelry expert Ashleigh Bergman, founder of Milestones by Ashleigh Bergman, examined photographs of the necklace while speaking with the Daily Mail.
According to Bergman, the piece appeared to feature graduated emerald-cut diamonds, with individual stones estimated to range from approximately three to five carats.
The necklace also appeared to have a much larger emerald-cut center stone, which Bergman estimated could weigh somewhere between 15 and 20 carats.
She suggested that the Riviera-style necklace may have been created by either Lorraine Schwartz or Samar Halimeh, two jewelry designers whose work Sánchez has worn in the past.

As for the potential value of the extraordinary necklace, Bergman offered an eye-catching estimate.
“I would assume this necklace would be around $10 million,” she said.
That figure only added another layer of fascination to Sánchez’s already highly discussed appearance.
Comparisons With Melania Trump
The attention surrounding Sánchez’s outfit eventually extended beyond her own appearance, with some online commentators comparing her look with that of First Lady Melania Trump, who hosted the evening alongside President Donald Trump.
Melania chose a noticeably different style for the black-tie event.
She wore a sophisticated black Dolce & Gabbana ensemble consisting of tailored trousers, a silk cummerbund and a white Saint Laurent blouse featuring an oversized bow.
The contrasting fashion choices quickly became a subject of discussion in fashion coverage.
While Melania opted for a more structured and understated interpretation of formalwear, Sánchez’s appearance was considerably more revealing and dramatic.
One outlet went as far as to claim that Sánchez had “outshined and outdressed” the First Lady, further fueling the conversation surrounding the two looks.
It Wasn’t Sánchez’s First Controversial Fashion Moment
The reaction to Sánchez’s White House appearance was not an isolated incident.
Her fashion choices have attracted controversy and intense public attention on several previous occasions, particularly when she has attended major political or diplomatic events.
In January 2025, Sánchez faced similar criticism over the outfit she wore to President Trump’s inauguration.
She also attracted significant attention in April 2024 when she attended the state dinner hosted by President Joe Biden and First Lady Jill Biden in honor of Japanese Prime Minister Fumio Kishida and his wife, Yuko.
For that occasion, Sánchez wore a striking crimson corset-style gown.
The dress featured an off-the-shoulder neckline, intricate lace detailing, structured boning and a floor-length skirt. She completed the look with metallic open-toe heels.
The dramatic red gown stood out against the traditionally formal atmosphere of the black-tie event and was described by some observers as one of the evening’s most daring fashion choices.
Once again, her appearance became a major talking point.
A High-Profile Relationship in the Spotlight
Lauren Sánchez and Jeff Bezos have been together since 2019, and their relationship has remained a frequent subject of public interest.
The couple became engaged in May 2023 after several years together.
They later married on June 27, 2025, in a lavish ceremony on the Italian island of San Giorgio Maggiore in Venice.
Since then, their appearances at major international events have continued to attract considerable attention, particularly because of their high-profile status and Sánchez’s distinctive approach to fashion.
At the White House state dinner honoring Xi Jinping, however, it was Sánchez’s black Alexander McQueen gown — and the enormous diamond necklace accompanying it — that became the center of the conversation.
The evening was intended to bring together political leaders, prominent figures and influential guests for a formal diplomatic occasion.
But by the time photographs of the event began circulating online, a different conversation had taken over social media: whether Lauren Sánchez Bezos had made a glamorous fashion statement or simply chosen an outfit that some viewers considered too revealing for the setting.
As with many high-profile fashion moments, the reaction ultimately depended on personal taste. Some saw confidence and glamour, while others saw a lack of restraint.
Either way, Sánchez’s appearance ensured that she would be remembered as one of the most discussed guests of the evening.
