If you’ve been paying close attention, you may have noticed the clues — a few quiet teasers and the slow unfolding of our Founder Cat Cason’s namesake line, Cat Cason.
For those who never miss a Gem Breakfast beat, the questions have been coming in. Is this a new line? What does it mean for Gem Breakfast? How do you actually shop it?
So, to our jewelry friends — the collectors, the admirers, the custom curators, our engagement ring couples, and all the treat-yourselfers — we’re here with answers. We sat down with Cat to get into it: why she started Cat Cason, the mood and design language behind it, and how to know which line matches your current craving.
Meet Cat Cason
Cat Cason is Cat’s newest jewelry line, created alongside Gem Breakfast but unfolding in its own world.
It draws you into something softer and more romantic — a place where tulle spins, chiffon catches the light just right, and small details start to feel like the whole point.
There’s a lightness to it, a sense of play, and that pull toward something a little dreamy, all grounded in what Cat calls girlhood wonder with grown-up elegance.
With a slightly more traditional bridal lens and a more personalized, one-on-one experience, Cat Cason balances delicacy with precision and romance with restraint.
It’s a different kind of energy. Composed, intentional, and quietly captivating.
Why Catherine Started Cat Cason
At a certain point, Cat kept coming back to the same ideas — lace, tulle, pleating, chiffon, and the way fabric holds both soft structure and fluidity.
At the same time, she was noticing how most fine jewelry tends to follow a few familiar design languages – ultra-modern and architectural or free-form and organic – without a lot of space for something that leans feminine and whimsical while still feeling fully resolved.
The more she explored it, the more it started to feel like its own direction. So instead of trying to fold those ideas into Gem Breakfast, she gave them a place of their own.
Cat Cason grew out of that — a counterpoint to Gem Breakfast, and a place for those ideas to take shape.
Cat Cason vs. Gem Breakfast
They come from the same eye, the same attention to detail, the same level of care. They just express it differently.
The vibe
Gem Breakfast is colorful, a little wild, and full of personality. It has a sense of humor and a kind of gregarious energy — pieces that feel like an extension of you the second you put them on.
Cat Cason is softer, more contained, and more intentionally feminine.
If Gem Breakfast is the bold alter ego, Cat Cason is the ballerina — composed, elegant, and somewhere mid-spin.

The design approach
At Gem Breakfast, the starting point is the stone. Color, cut, presence. Everything takes shape from there.
At Cat Cason, the attention expands towards form. There’s a stronger focus on detail, texture, and silhouette. Gold isn’t just a setting — it’s shaped, folded, and worked to create softness and dimension.
You see it most in the Plissé pieces. Inspired by a ballerina’s tutu, the goal was to translate something delicate and graceful — like lace or tulle — into gold. To capture that feeling of movement and airiness in something solid and enduring.
Who it’s for
With Gem Breakfast, you have an appetite for something with attitude. You’re pulled toward designs with a unique point of view — bold, a little unexpected, and full of character.
With Cat Cason, your taste runs more intimate and considered. You notice the details first, and you’re drawn to designs that feel refined, intentional, and quietly self-assured.
The Plissé: Where Fabric Becomes Gold
The design that inspired the line was the Plissé.
It started with the soft, gathered folds of a ballerina’s tutu, and how that sense of motion could be translated into gold — something Cat hadn’t seen before in fine jewelry.
Each ridge is shaped with intention, catching the light a little differently from every angle. The surface has a sense of movement to it, with depth and dimension crafted into every fold.
The inspiration is delicate, and the execution is highly considered — that level of precision is what makes it feel so easy once it’s on.
When Should You Shop Cat Cason vs. Gem Breakfast?
If you’re deciding between the two, it usually comes down to what you’re drawn to.
Go with Gem Breakfast when you want something expressive.
You’re pulled toward color, character, and gemstones with personality to spare. There’s a kind of chef-created, color-drenched magic to it — unexpected combinations and one-of-a-kind designs that feel alive the moment you see them.
Go with Cat Cason when you want something that feels singular.
Your eye goes to softness, detail, and proportion — the way everything is balanced and resolved. There’s a delicacy that still feels grounded and complete, with designs that lean more romantic, ethereal, and feel like they were made with you in mind.
