About the Brand

We're Marrow Fine

From statements to staples, Marrow Fine is redefining fine jewelry. We find inspiration from our Marrow Babes and the custom pieces we get to create for them, from heirloom reworks with special, meaningful stories to brand-new designs meant to make new memories. We only use the highest quality, hand-picked materials and love infusing our distinct designs with rare, unusual diamonds and gemstones.

We have an eye for the unordinary and a love for all things old, unusual, and often overlooked. We believe beauty can be found in everything; every moment shared; every memory kept close; and every forgotten jewel that just needs to find its shine.

Our Jewelry Ethos


We believe fine jewelry isn’t just for special occasions. Using high quality, hand-picked materials, our long-lasting designs are meant to celebrate the everyday.


If it’s special to you, it’s special to us. We love working with clients to reimagine the “old bones” of any heirloom piece to hold a memory, pass down a story, or create a new tradition.


We’re more than the sparkly stuff. Our pieces are started from sketch in house by our female-led design team. Partnering with like-minded social organizations, we’re committed to making a difference in our community and in the world.

Meet Jillian Sassone

After being in the corporate grind for 15 years, I started Marrow as a passion project. Inspired by the many places I’ve lived, from the stormy Pacific Northwest to the art of New York and the mid-century appeal of Palm Springs, each design is infused with a little something from my past.

The passing of my grandma Mary was what really set things in motion. What began as reworking the heirlooms she left into new pieces that felt fresh, soon grew into a long list of clients who wanted to do the same. Almost everyone I know has a box or drawer full of old baubles with heaps of sentimental value that need to be liberated with a fresh design eye. Working closely with clients to carry on a story through a cherished treasure is my favorite aspect of my work.

Like many passion projects, Marrow snowballed very quickly into a living breathing company and in 2017, we hired our first employee and released our first full line. Soon after, my husband Tim left a successful career to join the team — which I was immensely grateful for. Since then, we have grown the team and outgrown our design studio in Solana Beach. In 2019, we opened our first flagship shop at One Paseo in Del Mar where I get to continue working closely with clients — the part of the job I’ll always love most. While the brand continues to grow, the meaning, sentiment, and reason why I started will always remain.

What we do

Modern yet timeless, alternative but classic, Marrow Fine specializes in the unexpected. We source stones from all over the world and are constantly working on elevating our designs to create pieces you literally can’t find anywhere else. Whether you’re looking to turn your grandmother’s band into an engagement ring or start completely from scratch, we’d love to be part of your story.

Get Started

“I love the process that goes into creating something. The unexpected details, the history of an heirloom piece, and ultimately turning the dreams of my clients into reality.”
