SPARKLE WITH SUBSTANCE
Fine jewelry, designed for real life.
Marrow Fine is an independent fine jewelry house, established in San Diego, California in 2016 by designer Jillian Sassone. From the beginning, our conviction has been simple: fine jewelry deserves a place in everyday life, not a velvet box reserved for special occasions.
Our designs balance modern style with timeless craftsmanship, crafted from exceptional materials sourced with the same care we bring to the design itself.
The result is jewelry made to be lived in — a signature you reach for without thinking, an heirloom in the making, made with the kind of intention that lasts.
Meet Jillian
“My journey as a designer began with an heirloom rework for my grandmother, Mary — reimagining her jewelry into something new to make my own. That one project opened my eyes to the power jewelry has to carry history while taking on an entirely new life, and it continues to shape the way I approach design today.
Inspiration finds me everywhere, from architecture and travel to the textures, colors, and quiet details of nature. My hope is that every Marrow piece feels beautifully made, deeply personal, and becomes something you'll reach for instinctively for years to come."

Jewelry with good bones.
The name Marrow was inspired by the idea of good bones — recognizing the beauty in what already exists and preserving what makes it special.
From heirlooms passed down through generations to antique diamonds with a history of their own, we've always been drawn to jewelry that carries a sense of permanence.
Thoughtful materials,
chosen with intention.
chosen with intention.
We partner with trusted suppliers and skilled artisans to source reclaimed gold whenever possible, along with responsibly sourced diamonds and gemstones chosen for their beauty, character, and individuality. We're especially drawn to antique diamonds and one-of-a-kind stones—materials that bring a sense of history and make each piece feel truly unique.
Every decision, from sourcing to craftsmanship, is guided by the same principle: creating jewelry of lasting quality that you'll wear and love for years to come.
