One-of-a-kind
Custom
& Heirloom
Whether we’re starting from scratch or rebuilding the bones of an heirloom piece, we collaborate with you to bring life to your ideas.




Marrow custom
Honor the past
From dream to design, we can’t wait to work our magic and create a completely custom Marrow piece that’s one-of-a-kind—just like you.
Break the mold
It all started with an heirloom from Jillian’s grandmother. To rework a piece with history and create something even more special—all while honoring the past. This idea sparked a list of clients looking to liberate their heirlooms with a fresh eye for design.












Process & Timeline
Week 1-2
Let's chat
First things first. Start by booking an appointment with one of our stylists and sharing your inspiration, budget, stone preference, and general information.
Once we have the details, we can begin to create your personalized design.
Week 2-4
From dream to design
After we sit down with you and take the initial deposit, our design team will get to work bringing your vision to life, whether that means heading right to sketch or sourcing the stone of your dreams.
Once you’re over the moon about the design direction, it's time to move the project into production.
Week 4-10
Make magic & celebrate
From start to finish, the magic-making timeframe is typically 8-10 weeks. When the design is finalized, we create a 3D rendering of your ring.
Once that is approved, production begins and in about 4-6 weeks, she’s all yours, baby!
One-of-a-kind, ready to ship.

Custom FAQ's
Our turnaround for custom projects is based on a number of factors - including multiple rounds of CAD revisions, complex custom pieces, and client stone approvals - but is typically 8-10 weeks from initial deposit payment.
All domestic pieces are shipped via FedEx and fully-insured. All deliveries require a signature, so keep in mind when entering your shipping information. For local clients, we offer showroom pickups.
International pieces will be via DHL Overnight Delivery (where applicable) and fully insured. We do not cover the cost of international taxes and duties.
Marrow guarantees the structural integrity of all jewelry. Please be mindful that it is important to add fine jewelry to a homeowners, renters, or individual policy; this will protect against loss, damage or theft of jewelry.
Should repairs be needed, it is the client’s responsibility to ship and insure the piece(s); Marrow Fine Jewelry will return jewelry via insured shipment. Center stones are not under warranty, please insure your piece.
We will replace melee diamonds within the first 6 months (2mm and smaller) free of charge. Should there be damage to the piece (missing prong, etc), Marrow will replace the diamonds/stones at cost to the client.
Other stones (emeralds, opals, sunstones, other colored gemstones, etc) can be replaced at cost + shipping to the client. Please be mindful that sunstones and opals have a similar hardness to a wine glass and can easily crack or chip if they are not cared for properly. Emeralds are considered a brittle stone and can chip as well.
