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

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 collect a deposit and officially begin personalizing your design.

Week 2-4

Sourcing your stunner

After we sit down with you and take the initial deposit, our team will get to work sourcing your gemstone along with any other supporting materials to help fully build out your custom concept. Feel free to share any inspo pics from our web or Instagram with your stylist! If we've sourced it before, we can likely do it again.

Week 4-6

From dream to design

Once you've selected the perfect stone, it's time to start bringing your vision to life. Whether that means creating a custom design package or skipping right to generating some 3D renderings, we share all of the visual things for your approval.

Once you’re over the moon about the design direction and all of the little details, it's time to move the project into production.

Week 6-12

Make magic & celebrate

From start to finish, the magic-making timeframe is typically 8-12 weeks. When the design is finalized, we'll create a one-off mold and our master jeweler will cast and create your one-of-a-kind piece.

Production typically takes about 4-6 weeks, including a thorough quality check and appraisal upon completion. Then... she’s all yours, baby!

Custom FAQ's

How long does a custom project typically take?

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.

How will I receive my finished piece?

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.

Do you have a craftsmanship warranty?

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.

Do you have a stone warranty?

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.

Do you source stones?

Yes! Who doesn’t love a good treasure hunt? We have our own internal QA team and work with fully vetted/trusted partners.  

Will you work with a stone I sourced myself?

At this time, we only work with heirloom stones and stones that we source ourselves.

Do you work with lab-created gems?

Currently, we do not work with lab created gemstones or moissanite.

Do you appraise pieces?

Yes, we offer appraisals via a local, trusted third-party appraiser.

How will I know what my custom piece looks like before it is finished?

Our design team will provide you with some design options that you can select from. Once the design is approved, we will create a 3D rendering of your ring so you can see exactly what it will look like once it's finished.

Do you offer jewelry repair?

We guarantee the integrity of our own work, and will go above and beyond to ensure our customers are thrilled with their experience. We do not offer repair service on other jeweler’s or designer’s work.

Please see our FAQs for more details.
