DESIGN PROCESS

See It Clearly Before It Is Made

A reference, a gemstone or simply an idea can be the beginning. Sookjai brings each decision into view—from the first concept to the final piece—so you can move forward with clarity and confidence.

FROM IDEA TO APPROVED FORM

From Reference to Concept.
From Concept to an Approved Form.

The idea becomes visible before technical design begins—giving you a clear direction to consider, refine and approve.
TWO WAYS TO BEGIN

Your Stone or Ours

Begin with a gemstone chosen from our collection or one already meaningful to you. Each is considered individually before the design takes shape.
01

A Stone from Sookjai

Choose from a curated collection of gemstones selected for their beauty, character and potential to become something personal.

02

A Stone You Already Own

Bring a gemstone you already value. We examine, measure and document its condition before considering how it can be set beautifully and securely.

FROM REFERENCE TO CONCEPT

The Idea Becomes Visible

A reference gives us the direction. Concept visualisation places your gemstone within it, allowing the overall form, proportion and character to be considered before technical design begins.
01

Reference

A design, image or idea establishes the direction, details and character you are drawn to.
02

Concept Visualisation

Your gemstone is placed within the chosen direction so the overall look can be explored and refined.
03

Approved Direction

Once the form and character feel right, the confirmed concept becomes the reference for quotation and CAD.
THE DESIGN JOURNEY

Every Decision in Its Right Place

From the first conversation to final delivery, each stage resolves one decision before the next begins.
01

Begin with Your Stone

Choose a gemstone from Sookjai or bring one already meaningful to you.
02

Define the Direction

Share the reference, material, occasion and date by which the piece is needed.
03

See the Concept

Review a visualisation of your gemstone within the proposed design and refine the direction.
04

Confirm the Proposal

Feasibility, material, price and production time are confirmed before work begins.
05

Approve the CAD

Review accurate proportions, dimensions, setting details and simulated metal colour before production.
06

Follow the Making

The approved form enters production, with meaningful updates shared as the piece progresses.
07

Review the Finished Piece

Final photographs and video allow the completed piece to be reviewed before the remaining payment.
08

Receive with Confidence

Your piece is prepared with its documents and care materials for collection or secure delivery.

APPROVED IN CAD

Every Detail, Resolved Before Production

CAD turns the approved concept into the technical form from which your piece will be made. Sookjai reviews the render point by point against the direction you confirmed, while dimensions, setting and material requirements are resolved around the actual gemstone.

You receive renders from multiple angles and may refine the proportions, thickness, prongs, shoulders or surrounding stones until the design feels right.

KEPT INFORMED

You Remain Part of Every Decision That Changes the Piece

Once the CAD is approved, Sookjai follows production on your behalf. Updates are shared at the moments that matter—before plating, and again when the finished piece is ready for final review.

You remain informed without having to carry every uncertainty of the workshop.
If production requires a change to the approved direction, the decision returns to you before work continues.
BEFORE PLATING
The completed form is shared as the piece approaches its final finish.
AFTER COMPLETION
Final photographs and video allow the finished piece to be reviewed before delivery.

ENTRUSTED TO US

Your Gemstone, Treated with the Utmost Care

When you entrust us with a gemstone of your own, its condition is established before design or production begins. We inspect the stone, record its dimensions and weight, photograph existing marks and discuss any considerations that may affect setting.

You review and confirm this record before the gemstone enters our care, giving both you and Sookjai a clear point of reference throughout the work.
INSPECTED
Surface, clarity and existing condition.
MEASURED
Dimensions and weight recorded accurately.
DOCUMENTED
Detailed photographs retained as a condition record.
RISK REVIEWED
Setting requirements and known vulnerabilities considered.
If a gemstone is damaged as a direct result of our work, Sookjai takes responsibility for sourcing and cutting a replacement as close as reasonably possible to its original character and condition.
READY FOR YOU

Final Review and Delivery

Once every stage is complete and the piece has passed final inspection, we prepare photographs and video for your review. The remaining balance is settled only after you have seen the finished result.

Your piece is then prepared with its jewellery box, polishing cloth, material details and warranty. A gemstone certificate is included where applicable.
FINAL REVIEW
Photographs and video of the completed piece.
TYPICAL TIMING
Approximately two weeks to one month from payment, depending on the design and current production schedule.
FINAL PAYMENT
The remaining balance is settled after the finished piece has been reviewed.
DELIVERY
Collection near Silom, trusted Bangkok delivery, Grab or EMS.
