Jewelry CAD Design Services
From sketch to production-ready 3D model — built by a master jeweler with 40+ years at the bench. STL, OBJ, and native CAD files ready for casting, printing, or CNC.
About This Service
From Any Starting Point to a Perfect 3D Model
Whether you are starting from a rough pencil sketch, a photograph of an existing piece, or a verbal description, our jewelry CAD design service transforms your concept into a precise, production-ready 3D model. Every CAD file is built with manufacturing in mind — wall thickness, stone seats, sprue placement, and polishing access are all considered before the first revision is sent.
Todd Michael brings over 40 years of hands-on goldsmithing to every model. That depth of bench experience means structural integrity, accurate prong and bezel geometry, and real-world wearability are built in from the start — not flagged by your casting house after the fact.
We work with independent jewelers, emerging designers, and jewelry manufacturers across rings, engagement rings, pendants, earrings, bracelets, and bespoke custom pieces of all complexity.

What's Included
Everything You Need, Nothing You Don't
Sketch-to-CAD Conversion
We work from any reference: pencil sketches, phone photos, magazine clippings, or verbal descriptions. Any starting point is the right starting point.
Production-Ready Files
Every file is built for manufacturing. STL, OBJ, and native CAD formats optimised for lost-wax casting, resin 3D printing, and CNC milling — delivered ready to send to your caster.
Precise Stone Seat Modeling
Prong, bezel, channel, pavé, and flush settings built to exact stone dimensions. No guessing at the bench — every seat is modeled to the actual girdle diameter and depth of your stones.
Unlimited Revision Rounds
We iterate until the model is exactly right. Proportion adjustments, shank profile changes, stone repositioning — revisions are part of the process, not an add-on cost.
40+ Years of Manufacturing Insight
Every structural decision is informed by decades at the bench. Wall thickness, undercuts, sprue placement, polishing access — manufacturing realities are built in from the first line, not flagged after the fact.
Fast, Reliable Turnaround
Professional workflows and deep expertise mean most projects are completed in 3 to 7 business days. Rush service is available when deadlines are tight.

How It Works
Simple. Collaborative. Precise.
Share Your Reference
Send a sketch, photo, reference image, or written description. Include any stone sizes, metal preferences, and specific details that are important to you.
Brief & Scope
Todd reviews your project, asks any clarifying questions, and confirms the approach, expected complexity, and turnaround timeline before work begins.
3D Modeling & Revisions
You receive the 3D model with screenshots or renders for review. Revisions are made until every detail — proportion, stonework, surface — matches your vision.
Final Production Files
Production-ready files in your required format, sized and structured for your casting house, 3D printer, or CNC mill. Ready to manufacture.
FAQ
Common Questions About Jewelry CAD Design
What file formats do you deliver for jewelry CAD design?
We deliver STL, OBJ, and native CAD files (3DM for Rhino, ZPR for ZBrush, or the format required by your casting house or 3D printer). If you need a specific format for your manufacturer, wax printer, or CNC mill, just let us know and we will deliver accordingly.
Do I need to provide a sketch to start a jewelry CAD project?
Not at all. We work from any starting point — a rough pencil sketch, a photograph of an existing piece, a reference image from online, or even a verbal description. Todd's 40+ years of goldsmithing experience means he can translate almost any vision into an accurate 3D model.
How many revisions are included in a CAD design project?
We include multiple revision rounds in every CAD project. Our goal is to deliver a model that you are completely satisfied with before final files are sent. We iterate until the 3D model matches your vision precisely.
How long does a typical jewelry CAD design project take?
Most standard jewelry CAD projects — rings, pendants, simple earrings — are completed within 3 to 7 business days. More complex pieces with intricate stonework, engraving, or custom mechanisms may take longer. Rush turnaround is available on request.
Can you CAD model an existing piece of jewelry for reproduction or redesign?
Yes. Send us the physical piece, a set of photos, or precise measurements and we will build an accurate digital replica. This is ideal for reproduction, resizing, updating a vintage design, or creating a matching companion piece.
