To-CAD

From Concept to Precision

Once your concept direction is approved, we begin the CAD stage, the part of the process where your design becomes a precise, manufacturable 3D model.

If the Concepts stage is about creativity, CAD is about engineering. Every angle, proportion, and structural detail is built with production in mind.

Our goal is simple: turn your approved concept into a CAD model that’s accurate, beautiful, and ready for the next step of jewellery manufacturing.

What Happens During the
CAD Stage

1. Translating Your Concept into a 3D Model

Your 2D sketch is transformed into a detailed digital model using professional jewellery CAD software.

This ensures the piece is built with:

  • Correct proportions
  • Proper stone tolerances
  • Realistic metal thickness
  • Structural strength
  • Sizing for wearability

This is the stage where we engineer the piece exactly as it will be produced.

2. Professional Renders You Can Review Clearly

When the CAD model is complete, you receive clean, high-resolution renders showing:

  • Top, front, side, and perspective views
  • Stone arrangement and sizes
  • Metal appearance and detailing
  • Structural elements not visible in 2D sketches

These renders help you visualize your jewellery as it will look in real life.

Example Timeline & Workflow

Day 1-2

CAD model creation

Day 3

Internal review and refinements

Day 4

Renders prepared and sent to you

Share your vision

Day 1-2

Send us your hand sketch, digital drawing, or mood board.

Day 3

We translate your concept into CAD models.

Day 4

We create a physical prototype.

Revisions & Feedback

Small adjustments at this stage are normal and encouraged.
You can refine:

Stone sizes

Detailing

Structural elements

Engravings or accents

Making changes in CAD is faster, cleaner, and more cost-effective than changing anything later during prototyping or sampling.
This is why CAD is such an important part of the jewellery design process.

Approval: Moving Into Prototyping

Once you approve the CAD model:

  • We finalise the files
  • We prepare your model for 3D printing, wax carving, or direct casting
  • The project moves into the Prototyping stage

Every step that follows — wax, cast, sample — depends on the accuracy of your CAD model.
 This is the foundation of your finished piece.

What Your Design Journey Looks Like

From sketch to finished jewelry, your design moves through a clear set of stages. Click through to see what happens at each step and how your idea comes to life.

Brief

What you submit, what a “good” sketch includes, and what information is required to start.

Concepts

Creative direction, mood boards, alternate concepts, ownership, and 2D sketches.

CAD

Design translated into CAD, checked for feasibility, structure, stones, and production readiness.

Prototyping

Choosing the right prototype approach (3D print, wax, direct cast) based on the design.

Sample Approval

What is shared for approval and how revisions are handled.

Next Step: Concepts

After your brief is approved and payment is made, we start developing visual directions, exploring styles, materials, and interpretations of your idea before moving into CAD.
