From idea to manufacture

Jewelry CAD and Product Development

A sketch can establish an idea, but a manufacturable piece needs its form, materials and stone placement considered together. BCJExport develops custom jewelry designs with CAD as part of its Bangkok B2B manufacturing work.

SKETCH TO CAD

Start with the reference you have.

A project can begin with a hand-drawn sketch, photograph, idea or an existing CAD file. From there, our CAD team develops the design around the intended piece — its proportions, gemstones, setting, construction and finish.

If you already have a CAD file, we can review it and make any adjustments needed before production.

Typical CAD development takes approximately 2–3 days, depending on the complexity of the design.

What development needs to resolve

Before a piece moves into production, the important details need to work together. Proportion, gemstones, setting and construction are considered as part of the same design.

01 / PROPORTION

Proportion and wear

How should the piece sit and be worn? The relationship between the central feature and the surrounding metal matters in a ring, pendant or earring. Communicate the silhouette you want and any reference views that show its scale.

02 / STONES

Metal and stones

The proposed metal, stone shape and intended setting all inform the design. Gold and platinum choices can be explored in the context of the piece; read our materials guide. If stones have not been chosen, gemstone sourcing can be part of the wider brief.

03 / CONSTRUCTION

Finish and structure

Setting, surface finish and construction need to work together so the piece can move clearly from design into the workshop.

Review before production

Review the design before production

The CAD gives you an opportunity to review the piece before it enters the workshop.

This is where proportions, stone placement, setting details and the overall appearance can be checked and adjusted if needed.

Once the design is approved, the project can move forward into production with a clear reference for the workshop.

From approved design to production

Once the design is approved, the workshop follows a clear sequence through the remaining stages.

  1. 01

    Approved Design

    The approved design provides the reference for the workshop.

  2. 02

    Manufacturing

    The piece is made according to the agreed design and materials.

  3. 03

    Setting

    Stones are set in line with the intended arrangement.

  4. 04

    Finishing

    Polishing and any agreed surface details are completed.

  5. 05

    QC

    The finished piece is checked before handover.

Preparing your enquiry

What would help us understand the concept?

When you send a design enquiry, consider these prompts as questions to answer rather than a required checklist:

  • What is the intended piece, and who is it for?
  • Which views, sketches or photographs communicate the desired shape?
  • What metal direction and stone details are known, and what remains undecided?
  • Will customer-supplied stones be involved where appropriate? If so, what information about them is available?
  • Which details are essential to the design, and which are open to discussion?
  • Is the intended outcome a finished jewel, semi-mount or unset piece?

These answers help start a useful conversation; they do not prescribe a particular CAD file format, number of review rounds or approval policy. Manufacturing is approximately 1–2 weeks depending on the job after design development; discuss your project timing in the enquiry.
