How It Works

Your vision,
realized.

Custom jewelry can feel overwhelming if you've never done it. Our process is designed to be the opposite — collaborative, transparent, and surprisingly enjoyable. You don't need to know exactly what you want. That's what we're here for.

01

Consultation

Bring a photo, a sketch, a family heirloom, or just an idea. We'll shape it into something buildable — and beautiful. No obligation, no pressure.

Design & Render

We design your piece in professional CAD software and produce a photorealistic rendering. You see exactly what you're getting before anything is made.

Physical Model

We 3D print a wearable model of your design. Try it on, hold it, approve it in person. Nothing moves forward until you're certain.

What We Create

If you can imagine it,
we can build it.

From classic solitaires to sculptural statement pieces — our design capability has no limits. Every style, every metal, every stone. If it can be designed and cast, we can make it happen in our studio.

Engagement Rings

The most personal piece of jewelry you'll ever give. We design custom engagement rings from scratch — your stone, your style, your story. No two are alike.

Start the conversation

Heirloom Remounts

Inherited a piece that doesn't fit your life? We redesign it into something you'll actually wear — honoring the stone and story while making it completely yours.

Bring it in

Custom Pendants

One-of-a-kind pendants designed around your stone, your concept, or your vision. From delicate to dramatic — we've built them all.

Get started

Wedding Bands

Custom bands designed to complement your engagement ring perfectly — or stand alone as a statement. Matching sets, stacking bands, engraved designs.

Design yours

Anniversary & Gift Pieces

Milestone gifts deserve something truly personal. A custom piece says what words can't — and lasts a lifetime.

Tell us your vision

Anything You Can Imagine

Earrings, bracelets, brooches, cufflinks — if you can describe it, we can design it. Our studio has no limits on creativity or capability.

Let's talk
Our Technology

State of the art.
All under one roof.

CAD

Professional CAD Design

We design every piece in professional jewelry CAD software, producing photorealistic renders so you see exactly what you're getting before anything is cast.

3D

3D Printing & Physical Models

Large and small format 3D printers in-house. We print a wearable resin model of your design so you can try it on and approve it before we cast.

Laser Welding & Engraving

State of the art laser welder and laser engraver on-premises. Precision repairs, custom engraving, and finishing work that most shops send out — we do it here.

🔥

In-House Casting

Professional casting machines on-site. Gold, platinum, silver — we cast everything ourselves. No sending your piece to a casting house in New York.
