When Arianna Salerno first moved to Washington, D.C., in 2022 to attend Catholic University she didn’t see many people wearing cross necklaces. But in the past year, she says she has noticed an uptick of the jewelry each time she takes the Metro, and they are now a regular presence on Capitol Hill, where she’s held multiple internships.

As a millenniums-old symbol of Christian faith, the cross would seem somewhat immune to trendiness. But cross necklaces and pendants have been in vogue before and may be again as some feel more comfortable embracing their faith and seek community with others.

On red carpets, on social media, at protests by high-ranking Democrats and in the White House, necklaces with cross pendants are appearing with renewed prevalence. Chappell Roan wore an oversize one to the MTV Video Music Awards in September, and one dangled from Sabrina Carpenter’s neck in the music video for her single “Please Please Please.” The trendy online store Ssense sells them in nearly 50 variations, and mainstream jewelers like Kendra Scott and Zales carry numerous designs.

Lately, the cross necklaces flash across cable news screens several times a week, suspended between the collarbones of Karoline Leavitt, the White House press secretary, and Attorney General Pam Bondi.

Ms. Bondi, 59, wrote in a statement that her necklaces are an expression of her “strong Christian” upbringing: “My faith is very important to me,” she said. “It is what gets me through each day.”

Across TikTok, young Christian women have been sharing the meaning behind their own cross necklaces, saying they help cultivate a sense of belonging and connection with others.
