Belly Debuts Her Delicate Engagement Ring on <i>The Summer I Turned Pretty</i>

If you were surprised that Jeremiah Fisher proposed to Belly Conklin without a ring—and without kneeling!—in the season 3 premiere of The Summer I Turned Pretty, then let the newest episode make up for that. In this week’s chapter of the Prime Video series, Jeremiah finally gets down on one knee and asks for Belly’s hand in marriage with a proper diamond.

The ring in question is The Diamond Fizz Ring from Catbird. It’s a sweet and delicate piece that fits Belly’s youthful, summery style, consisting of a yellow gold band and a round white diamond. This just marks one of the many ways the Brooklyn-based jeweler teamed up with TSITP for its third and final season. The brand and the show also collaborated on a seven-piece collection inspired by Belly’s story and summery themes, from infinity-shaped rings (if you know, you know) to seashell charms.

Below, Catbird’s chief creative officer Leigh Batnick Plessner spills all the details on Belly’s new bling.

Catbird Diamond Fizz Ring

First, let’s lay out the stats: The Fizz Ring is made of 100-percent recycled, solid 14K yellow gold with a band measuring about .80mm. As for the stone, it’s a 3mm-round, .089-carat recycled white diamond with a brilliant cut.

The piece currently retails online and in stores for $289. A petite version is priced at $168.

The Catbird team primarily works with 14K gold, and this ring is only offered in that material because of its size. Silver would’ve been “too delicate,” Plessner tells ELLE, “and we really want it to stand the test of time.” Which is exactly what you want in an engagement ring.

Plessner loves seeing how different people style the piece, whether that means wearing it on different fingers or stacking it with other pieces. “The diamond is slightly lifted so it can fit in with other rings [when stacked],” she says. (That might even include Belly’s future wedding band.)

The ring was not custom-designed for the series, but instead pulled from Catbird’s Fizz collection, which is made entirely with recycled brilliant cut diamonds and solid 14K gold. It first debuted “as we were emerging from COVID,” Plessner recalls. The name “fizz” was meant to evoke “a little bit of effervescence, and it felt so good to be out and about,” she says.

The design is intended for both everyday use and for engagements. “It felt equally perfect to me when they pulled that ring,” Plessner says of the TSITP team.

“Something that we always think about with our jewelry is this idea of how different people wear it, how it can shape-shift to suit your style, both in the moment and over time,” Plessner explains. “Or this idea of maybe one day a child finding a ring in their parents’ jewelry box and fitting it into their lives. So I think it suits young love because it’s so wearable and it can grow with you over time, and it can always suit whatever evolution of your personal style you might be in.”

Belly is 20 years old and a junior in college when she gets engaged, which means a ring like this can still match her style as she grows and evolves through the years.

The linkup began when Plessner received a personal Instagram DM from Carol Lim, a co-founder of Opening Ceremony and a close friend of Jenny Han, the author and showrunner of The Summer I Turned Pretty. “She’s obviously iconic New York retail royalty,” she recalls.

When meeting with Lim, “we started to talk about the idea of a collection and a collaboration, and we have some really massive Summer I Turned Pretty fans on our team as well, so everyone was really excited,” she says. And while the series might seem to cater to a younger audience (we adult women who binge the show after work beg to differ), there’s something universal about its romantic and summery appeal.

“Everybody has a relationship with summer, but this idea of this pocket of time when the beach is so special—that feels really connected to an East Coast summer experience I’m so familiar with,” Plessner says.

Belly’s ring captures a rising ethos around engagement rings rather than a specific trending design. The Fizz Ring, like many of Catbird’s offerings, can be described as “jewelry that makes you feel more like yourself,” according to Plessner. “In that sense, it’s really reflective of a moment where people really feel free to pursue their path.”

Belly knows how to do exactly that. As Lola Tung, the actress behind the character, recently told ELLE, she knows what she wants, even if that means facing criticism for getting married at a young age. “She knows she’s young, but she’s also quite stubborn and is making decisions for herself,” Tung said. “She’s like, ‘I need to do what I need to do for myself to protect myself, and to feel safe, and to feel like I am in control of my story and my life.’”
