CAD Modeling
Parametric, production-accurate models built in Rhino and Matrix — correct wall thickness, prong geometry, stone seats and casting tolerances from the first version.
CAD Modeling · Design · Rendering
Jewelry designed in 3D,
built for production.
Cast Jewels turns sketches, reference photos and rough briefs into production-accurate CAD models, photorealistic renders and casting-ready files — for jewelry brands, manufacturers and wholesalers worldwide.

What we do
Everything between an idea
and a finished casting.
We work as the 3D department for brands that don't have one — and as extra capacity for the ones that do.
Design & Concepting
From a reference photo, a napkin sketch or a written brief to a resolved design, with proportion, stone layout and metal weight considered before modeling begins.
Photorealistic Rendering
Studio-grade renders for catalogs, e-commerce, lookbooks and pre-sales — so you can show and sell a piece before a single gram of metal is cast.
Production-Ready Files
STL, 3DM, OBJ and STEP exports checked for printability, delivered with a stone list, metal weight estimate and casting notes.
Organic & Sculpted Detail
ZBrush sculpting for filigree, florals, engraving, textures and figurative work that parametric CAD alone can't reach.
Redesign & Rebuilds
Rebuild legacy pieces from photographs, resize a model across a full range, or adapt an existing design to a new stone, metal or price point.
Interactive delivery
Turn it. Inspect it.
Approve it.
Every project can ship with a browser-viewable 3D model, so your team and your clients can examine the piece from any angle before approval — no software to install, nothing to download, just a link.
- Rotate, zoom and inspect from any angle
- Switch metals without a re-render
- Wireframe view to verify topology and build quality
- Shareable link for client sign-off
Sample model shown. Your piece can be delivered the same way — a link your client opens in any browser.

How it works
A predictable process,
start to casting.
-
01
Brief & references
Send a sketch, a photo, a spec sheet — or just describe it. We confirm stone sizes, metal, finger size and budget before anything is modeled.
-
02
Concept & feasibility
Proportions, stone layout and estimated metal weight are checked first. Anything that won't cast cleanly gets flagged here, not after you've paid for a print.
-
03
CAD modeling
The piece is built to production tolerances, with correct seats, prongs, wall thickness and clearances throughout.
-
04
Render & review
Photorealistic previews, turntable views and an optional 3D viewer link for sign-off, with revisions until the design is right.
-
05
Production files
Final .3DM, .STL and .STEP files delivered with a stone list, weight estimate and casting notes — ready for your printer or caster.

Questions
Frequently asked
What do you need from me to start?
A sketch, a reference photo or a written description is enough to begin. The more you can tell us about stone sizes, metal, finger size and intended price point, the fewer revisions we'll need later.
How long does a model take?
It depends on the complexity of the piece, so every project is quoted with a timeline before work starts — you'll know the delivery date up front. Rush turnaround is available when you need it.
Do you sign NDAs?
Yes. We're happy to sign your NDA before you share a brief, or provide ours. Client work is never published without written permission.
Can you model from a photo of an existing piece?
Yes — reverse-engineering from photographs is routine work, whether you're rebuilding a discontinued line, restoring an heirloom or adapting a design to new dimensions. Clear photos from several angles with a scale reference give the best results.
Are the files ready for 3D printing and casting?
Every file is checked for watertight geometry, wall thickness, stone seat depth and prong clearance before delivery, and exported at the tolerances your printer needs. We include a stone list, an estimated metal weight and any casting notes worth flagging.
Who owns the finished files?
You do. Full rights to the delivered files transfer to you on final payment, with no ongoing licence or usage restriction.
How does pricing and payment work?
Most work is quoted per piece after we see the brief, so you know the cost before anything starts. Collections and repeat catalog work are priced per batch. Payment terms are agreed up front and confirmed in writing.
