One partner.
Distinct possibilities.

For Korean, UK, and US brands,
creative teams, and corporate gifting projects.

02 / CONSULTANCY TO MANUFACTURING

Design intelligence.
Production expertise.

JCCO is a Seoul-based jewelry design consultancy and manufacturing partner. We develop jewelry, objects, and IP collectibles for brands in Korea and internationally.

Start with design consultancy, commission 3D CAD and sample development, or bring an established design for private-label jewelry manufacturing. We also review OEM production briefs, with scope defined around the support your team needs.

01

Design consultancy

Shape a jewelry or object concept through design direction, material selection, proportions, and production advice. Make informed decisions before committing to development.

IDEA → DIRECTION
02

3D CAD & product development

Develop the design through 3D CAD, construction review, and physical samples. Refine form, details, and finish before production approval.

DIRECTION → SAMPLE
03

Jewelry & object manufacturing

Coordinate limited runs and scaled production around an approved sample. Align quantities, finishes, quality reviews, branding, and presentation.

SAMPLE → OBJECT

Project scope, minimum quantities, material suitability, packaging, and lead times are confirmed after review. Testing and certification requirements should be raised at the briefing stage.

03 / IP INTO OBJECT

Your IP.
In a new dimension.

CHARMS · MINIATURE OBJECTS · LIMITED EDITIONS

Collectible objects with a brand’s identity in every detail.

From your own or licensed IP, we explore how a character, emblem, or story can take physical form. Jewelry-led collectibles, sculptural charms, miniature objects, and limited editions are developed around the intended audience and material.

BEFORE YOU BEGIN

A few things to know.

Where is JCCO based, and can UK and US brands work with you?

JCCO is based in Seoul, South Korea, and welcomes briefs from Korean companies and UK and US jewellery brands. Project discussions can take place in English or Korean. Destination-market requirements are reviewed during briefing.

Can we begin with consultancy or development only?

Yes. A project can focus on design direction, material and production advice, or CAD and sample development. We agree the deliverables and scope before work begins; manufacturing can be considered separately.

Do you work from our designs, or develop new ones?

Both. JCCO can develop a direction from your brief or review existing drawings, CAD files, and samples for OEM production. The scope is agreed around the support your team needs.

Can you support small batches and larger production runs?

Yes. We review limited runs and larger production projects. Minimum quantities, capacity, pricing, and lead times depend on the design, material, finish, and required quality controls. Share your target scale so we can assess a suitable production plan.

Do you develop custom corporate and VIP gifts?

We welcome corporate gifting briefs for jewelry, metal accessories, key rings, keepsakes, and presentation objects. Branding, personalization, and packaging can be developed around the occasion and recipients. Feasibility is reviewed for each project.

Can you develop a collectible from our character or IP?

We can review your own or licensed IP for jewelry-led collectibles and objects. Share reference artwork, intended use, approximate scale, and any approval requirements. CAD development, sample revisions, and production are scoped around the design and material.

Which jewelry materials and finishes can we discuss?

Gold, sterling silver, plated finishes, stones, and enamel can be discussed alongside the design. The suitable material, structure, finish, testing requirements, and production method are confirmed through project review and sample development.

Does creating a brief place an order?

No. A project brief is a starting point for discussion. Scope, costs, timing, and terms are agreed separately before work begins.
