Kate Bosworth confirmed her engagement to actor Justin Long on Instagram with a series of blurry photos of the two of them cuddling over the years.

“Mad Men” star Christina Hendricks announced her engagement to cinematographer George Bianchini with a low-key snap captioned: “We proposed and we said yes!!!” Allison Williams quietly let her partner Alexander Dreymon know about their upcoming nuptials — the “M3gan” star hasn’t posted on social media in about two years.

None of these women posted ring photos.

They didn’t show off the diamonds on their fingers or go on talk shows to share how their boyfriends got down on one knee. (Instead, Bosworth discussed the proposal on her fiancé’s “Life Is Short” podcast and let Long do the ring photo posting.)

It’s not just the announcements that have gotten smaller; the rings have too.

No more diamonds the size of the Ritz with flashy eternity bands. Brides are embracing simpler styles in traditional cuts.

“This year feels very different from 2022, where the focus was on really unique rings: heart shapes, portrait cut, vibrant colors – things that were unusual and stood out,” said Sam Broekema, editor-in-chief of Only Natural Diamonds, the Natural Diamond Council s online publication. “There’s been a real trend towards traditional and vintage styles – smaller natural diamond engagement rings, things that feel more understated.”

When newly engaged celebs did walk a red carpet, fans had to zoom in on the event photos just to catch a glimpse of their subtle sparkles.

“It feels calmer and more personal,” notes Broekema.

The yellow gold band’s interior features a tiny diamond that belonged to Roberts’ mother, while the exterior features an antique cushion-cut diamond surrounded by small pear-shaped stones, inspired by “a rare flower in bloom,” according to jeweler Michelle Oh.

It’s a lovely style that has an antique feel while remaining distinctly personal. “It’s definitely a retro throwback type of look,” says Scott Udell, vice president of London Jewelers. “But it has an elegant, New Age twist.”

Hendricks, meanwhile, opted for an antique style ring that complements her own preferences for 1940s-inspired fashions. “It consists of a group of stones, like Beanie’s,” says Broekema. “It’s more about the design than the impact of a central stone.”

“I think it speaks to the way they announced [the engagement] than to make the decision together,” Broekema points out. “It was: ‘We made a commitment to each other’ versus ‘He asked me and had to wow me to say yes to the ring.’ “

Udell says that brides who do opt for a single center stone also get them back: emerald-cut diamonds, as well as round stones and ovals with simple yellow gold or rose gold bands, as is the case with Bosworth and Williams.

“I think a lot of brides recognize that today [an engagement ring] is something they wear every day, day in and day out, and they want something that won’t be out of style in three to five years,” he says.

Even a pop star like Vanessa Hudgens (who showed off her ring in a selfie in front of the Eiffel Tower) held back the glitz, opting for an oval sparkler in yellow gold. Broekema says: “It’s a big ring, but it’s still very classic.”
