3D Jewelry Design Service
Jinnuo Jewelry helps brands, ODM buyers, private label teams, and boutique retailers convert sketches, reference images, samples, and CAD files into manufacturable jewelry designs for sampling and production.

Service Scope
Build accurate 3D jewelry models based on your idea, product direction, dimensions, materials, stones, and manufacturing requirements.
Turn hand sketches, simple drawings, or rough concepts into structured jewelry CAD designs with refined proportions and production details.
Convert reference images into customized jewelry designs while adjusting shape, scale, stone layout, brand details, and production feasibility.
Develop or improve a design from a physical sample by reviewing structure, size, weight, setting method, and manufacturable details.
Adjust existing CAD, STL, or 3DM files for new sizes, stone settings, logo placement, weight control, or production improvement.
Review weak points, thin areas, connection strength, mold requirements, and whether the design can be produced consistently.
Check stone size, setting position, tolerance, prong structure, bezel details, pavé layout, and inlay feasibility before sampling.
Prepare the approved design for mold making, sample development, surface finishing, logo engraving, and later bulk production.
During CAD development, we consider size adjustment, material choice, stone setting feasibility, weight control, logo placement, surface finish, and mold preparation from the beginning.
Buyer Preparation
Different buyers start from different levels of preparation. The table below shows how we turn each input type into a more production-ready 3D jewelry design.
| Input Type | Best For | Jinnuo Support |
|---|---|---|
| Sketch | Original ideas or rough concepts | Convert into CAD structure, refine proportions, and prepare design details |
| Reference Image | Style adaptation and private label development | Modify shape, scale, stone layout, logo placement, and manufacturability |
| Physical Sample | Reproduction, improvement, or collection updates | Review structure, adjust size, optimize weight, and prepare updated 3D design |
| Existing CAD File | Design modification or production feasibility check | Adjust size, thickness, stone setting, logo position, weight, and mold readiness |
Not sure whether your file or idea is enough? Send what you have, and our team will review the next design steps before sampling.
Send Your Design MaterialsDesign to Sample Process
Share sketches, reference images, samples, existing CAD files, logo artwork, or product concepts.
We review material, size, stone details, surface finish, logo placement, and target production plan.
Our team converts the approved direction into a structured jewelry CAD design for technical review.
Structure strength, stone setting, weight, thickness, size, and mold preparation are checked before approval.
Proportions, stone layout, logo position, size, and weight can be adjusted before sample making.
After design approval, we prepare mold or prototype steps and develop the physical jewelry sample.
Manufacturing Review

Send your sketch, CAD file, sample photo, or reference image for a manufacturability check.
Request a Design ReviewCheck thickness, weak points, connection strength, comfort, and sample stability.
Review stone size, prong strength, bezel depth, pavé spacing, and setting tolerance.
Adjust volume and thickness for cost control, wearing comfort, and target market positioning.
Confirm logo placement, engraving depth, brand tag position, and private label details.
| Review Point | Why It Matters | Common Adjustment |
|---|---|---|
| Structure | Reduces fragile or difficult-to-produce details | Increase thickness or reinforce connection points |
| Stone Setting | Improves stone security and production tolerance | Adjust prongs, bezel depth, or stone spacing |
| Weight | Controls cost, comfort, and product positioning | Refine volume, hollow areas, or wall thickness |
| Mold Readiness | Helps the design move smoothly into sampling | Clean details and prepare sample-ready structure |
