Gold Jewelry Manufacturer in Bangkok Thailand

Play With Diamonds is a gold jewelry manufacturer in Thailand, producing pieces for retailers, independent brands and wholesale businesses. Our Bangkok jewelry factory connects design development with CAD modeling, sampling, casting, stone setting, finishing and quality control.

We combine digital development with the skilled handwork of experienced Thai jewelry artisans. Our R&D Manager, Vladimir “Vova” Pantushin, leads design development, CAD and sampling, helping turn your ideas into practical designs for production.

Explore the stages below to understand how your jewelry moves from a design brief to a finished piece. For an original design, an adapted catalog style or a private label collection, start with our custom gold jewelry service.

Design Development and CAD Modeling

We review the intended shape, dimensions, gold karat, stone arrangement and functional parts before developing the design. CAD models help define proportions and settings for approval. A rendering is a design reference; the sample provides the opportunity to assess the physical piece.

Gold options include 9K, 10K, 14K and 18K, depending on the design. For 14K gold jewelry manufacturing, as with other karats, we confirm the alloy color, dimensions, stone choices and finish before you approve the production specification.

We use recycled gold in production. Discuss any specific recycled-content, material testing or documentation requirements during development so we can explain the available information before you confirm the order.

Prototypes and Sample Review

A prototype or sample allows the design to be checked before a production run. Agree the review points in advance, including dimensions, fitting, finish and stone layout. Revisions may affect weight, cost and schedule, so approve the final specification in writing.

Depending on the project, development can include resin or wax printing and a physical sample. We explain the stages your design needs before moving ahead.

Casting and Assembly

Approved models move into the manufacturing route appropriate to the design. Casting, component preparation and assembly need to preserve the intended shape while allowing for finishing. Connections and moving parts are reviewed as part of the finished construction.

For gold pendants, the approved specification should also cover the bail opening and its connection to the pendant body. These details help determine which chains can pass through the finished fitting.

Diamond and Gemstone Setting

Stone settings are developed around the selected stone dimensions and the design requirements. We work with diamond and colored gemstone designs, including wholesale diamond jewelry.

Specify whether you require natural or lab-grown stones, together with any treatment or documentation requirements. We confirm the selected stones and setting details before production so the approved specification identifies what will be used.

Finishing and Engraving

Filing and polishing refine the surface and edges after casting and assembly. Our artisans combine hand finishing with the equipment appropriate to each design.

Laser welding and engraving are used where appropriate to the construction. Discuss your brand mark, engraving position and required purity marking before approving the final production details.

Quality Control and Repeat Orders

Our quality control team checks the finished jewelry against the agreed specification. Dimensions, closures, stone setting, appearance and quantity are included in the approval criteria.

Keeping a record of approved samples and revisions helps a repeat order refer to the correct version. Supply your previous product reference when reordering, and identify any changes to materials, dimensions, finish or branding.

Plan Your Manufacturing Order

Send us the details of your collection so we can review the project and prepare a quotation:

Your sketch, reference images, technical drawing or CAD file.
Gold karat and color, dimensions, stones and preferred finish.
Quantities, branding requirements and target delivery date.
Any material testing, documentation or packaging requirements.

Made-to-order production normally takes 6–8 weeks after the deposit and final specifications are confirmed. Design development, sampling and revisions can add time, and shipping is additional. We confirm the schedule for your order and review any urgent deadline before you commit.

We prepare quotations manually and send them by email. For catalog designs, create an account to add your selection to the quotation cart. For a custom manufacturing project, send your brief through our custom jewelry service.

Review our material documentation and production and shipping information before confirming your order.
