Marrow offers one complimentary resize per piece, ensuring your fit feels just right.

A 2.25ct Old Mine Brilliant white diamond (I/SI2) set in a chunky 14k yellow gold bezel. Its classic cut and substantial size balance vintage character with a modern, clean silhouette—a timeless engagement ring.

Please note resizing this ring adds an extra 7-10 days for delivery.

Jillian's Design Notes:
"Our newest engagement ring style! I love the extra chunky bezel, exposed culet and that you can stack her with a straight band! We found this antique old mine cut that was likely cut in the late 1800s and I loved the idea of setting it in a clean, modern setting. This is a ring for girl who wants something completely unique and a true one of one piece."

Made for You

Rather than mass-producing, most Marrow Fine pieces are made to order — created in your exact size and selected gold. This slower, more intentional process allows us to craft thoughtfully, beginning your piece the moment you decide it’s yours.

Worn & Lived In

Made to be worn, loved, and truly lived in. We craft each piece in reclaimed 14k gold with ethically sourced gemstones, selecting every material with intention and longevity in mind. Designed for stacking, layering, and evolving with you.

Considered Crafstmanship

Each piece is cast, set, and polished by skilled jewelers who understand the nuance of fine jewelry. From the curve of a band to the final polish, every detail is considered — because pieces meant to last deserve nothing less.

As loved by

The attention to detail was over the top, but like in the best way, from the moment we walked in to the moment we opened the beautiful box. They know what they're doing here! Thanks again for everything!

Honestly, I have absolutely no words for how incredible Marrow Fine is. The detail, aesthetic and knowledge this showroom holds is truly one of a kind.

I worked with Marrow to pick out a new wedding stack after losing my wedding ring. I love Marrow's selection and style; there's nothing quite like it in the industry.

Marrow has been great to work with! We have been shopping from Marrow over the last two years and love their unique pieces.

Loved the experience I had! Have been searching for the perfect bands for a while and Marrow finally helped me find them!
