Charli XCX may have opted for a surprisingly traditional Vivienne Westwood dress for her Hackney Town Hall wedding at the weekend, but her choice of ring was far less by the book. While posing for photographs following the ceremony, the newlywed showed off a chunky platinum band sitting alongside her diamond solitaire engagement ring.

Save for her trademark sunglasses, the unusual choice of ring was arguably the Brat-tiest thing about her wedding look. “It feels modern and cool,” jeweler Jessie Thomas tells Vogue. “It’s chunky, textured and sculptural, which is a nice contrast to her classic solitaire engagement ring.”

While chunky engagement rings have been on the rise over the past year (see Dua Lipa), a growing number of brides like Charli are now opting for non-traditional wedding bands. “We’re seeing a clear rise in requests for more unique, design-forward wedding bands that contrast with the engagement ring,” Laura Vann, founder of Laura Vann Jewelry, says. “Brides today are looking for pieces that feel personal, and are less interested in conventional matching sets.”

As well as opting for a chunkier silhouette, many modern brides are incorporating diamonds into their wedding bands, as well as experimenting with mixed metals and hammered finishes. Having fun with the wedding band makes particular sense for those who didn’t get a say in the design of their engagement ring. “They can personalize [the wedding band] and make them suited to their personal style,” Thomas explains.

For brides who still want a classic wedding ring that isn’t the traditional band, an Art Deco-style ring is the perfect choice. “[They’re] bold but still timeless, allowing brides to express their personality while choosing something they’ll treasure forever,” Vann says.
