Who we are
The partner behind the piece.
ACCA Jewelry is a Hong Kong fine jewellery manufacturer. For thirty years we have turned client designs into finished pieces — rings, earrings, necklaces, pendants, bracelets and bangles — for premium brands, independent designers and chain stores around the world.
What sets a manufacturing partner apart is how the work fits together. A 2D design team and 3D CAD in Rhino and Matrix resolve proportions, construction and specifications on screen. 3D wax printing turns the approved model into something you can hold and review. Casting, filing, stone setting, polishing and plating then take place in our own facility, in karat gold, platinum and silver, so each step is reviewed against what came before it.
We are a collaborator first. Some clients arrive with a finished design and ask us to engineer, sample and produce it to specification. Others bring drawings, a sketch or a reference sample and want technical input. Some begin earlier still, with questions about customers, materials and technology. You choose where to involve us, from research support to production only, and we agree the scope, responsibilities and approvals together.
And the work stays yours. Confidentiality and respect for client intellectual property are central to our collaboration: your designs are used only for your project, and confidentiality requirements are agreed at the start.
Craftsmanship. Technology. Discretion.

Three decades
Thirty years of capability, in layers.
Rather than a list of dates, here is what thirty years has built: capabilities layered one on another, each carried forward into the next, none replacing the craft beneath it.

The bench
Handcraft foundations
Fine jewellery still begins and ends at the bench. Casting, filing, stone setting and hand polishing are skills built over three decades, and they set the standard every finished piece is judged against.

- Stone setting
- Hand polishing
- Plating

The model
CAD and wax printing
Digital development put the thinking in front of the metal. A 2D design team and 3D CAD in Rhino and Matrix resolve proportions, construction and stone layouts, and 3D wax printing makes the approved model physical before anything is cast.

The journey
The full development journey
Today the work reaches well beyond the workshop. A 24-stage journey runs from cultural change to the next product generation, with approval checkpoints along the way, and clients join at the stage that fits their project.

How we work with you
Four principles behind every project.
How a manufacturing partner behaves matters as much as what it makes. These four principles shape every project we take on.
-
Collaboration
Scope, responsibilities and approvals are agreed together.
Responsibilities vary by project, and we never assume we should lead every stage. Your brand can keep leadership of strategy, commercial direction and launch, while we contribute technical, manufacturing and research support where you want it. At the start we agree who does what, and where your approval is needed.
In practice
- Stage responsibilities are proposed, then confirmed with you
- Your team keeps direction of the brand, the range and the launch
- Our team contributes where you ask, from design development to production
-
Discretion
Your designs are used only for your project.
Your designs are your intellectual property, and we handle them that way. They are used only for your project, files are stored privately, and the terms of confidentiality are agreed at the start of each project, before sensitive files are shared if you prefer.
In practice
- Confidentiality requirements agreed at the start
- Design files stored privately and never publicly accessible
- Protected designs and private quotations visible to approved clients in Client Access
-
Precision
Resolved on screen. Reviewed against the specification.
Precision is built into the process rather than inspected in at the end. Proportions, construction, stone layouts and dimensions are resolved in CAD before any metal is cast, the approved sample becomes the reference, and each piece is checked against the specification agreed for the project.
In practice
- CAD review of geometry, dimensions, construction and stone settings
- A client-approved reference sample before production
- Final inspection against acceptance criteria agreed for the project
-
Flexible entry
Join at the stage that fits your project.
Some clients begin with research questions; others arrive with a finished design. We start where you are. Not every project uses all 24 stages, and the scope from your entry point onwards is agreed together.
Where are you today?
- I’m researching an opportunityExplore market, customer, material and technology questions before committing to a direction.
- I have a conceptDevelop and validate a concept into a resolved design with technical input from our team.
- I have a design to manufactureBring finished drawings or CAD. We engineer, sample and produce to your specification.

Our commitments
Agreed at the start of every project.
Every project is different, so each commitment is agreed per project rather than promised in general terms. These are the four we set out with you.
Project commitmentsAgreed per project
Confidentiality
Private by default. Formalised on request.
Confidentiality requirements are agreed at the start of each project. Design files sent through our enquiry form are stored privately and are not publicly accessible, and we do not share your designs with third parties without your consent. If you would like a mutual confidentiality agreement before files are exchanged, tell us and we will arrange it.
Agreed per project
- Confidentiality terms
- Handling of your design files
- Access to protected designs
Quality checkpoints
A review before each stage moves on.
Projects follow agreed approval checkpoints, from brief alignment to release and delivery. Inspection requirements and acceptance criteria are agreed for each project, and each piece is checked against that specification before it is released.
Agreed per project
- Approval checkpoints
- Inspection requirements
- Acceptance criteria
- Brief alignment
- Engineering review
- Sample approval
- Production readiness
- Quality review
- Release & delivery
Communication
You choose how we talk.
Tell us where your project stands and how you prefer to talk: by video call, email, WhatsApp, or in person at an exhibition. We reply to qualified enquiries with next steps for a meeting, and we agree with you how approvals are requested as the project moves forward.
Agreed per project
- Preferred channel
- Meeting format
- Approval milestones
Delivery planning
A planning range, confirmed by your project.
Delivery typically ranges from 14 to 45 days, depending on the project, once the sample and production requirements are approved. It is a planning guide rather than a blanket promise: timing, quantities and milestones are agreed for each project, with capacity of more than 10,000 pieces a month behind them.
Agreed per project
- Quantities and timing
- Release documents
- Packaging and shipment
Specific terms are confirmed in the development brief and technical specification for your project.
Looking forward
Looking forward, we continue to invest in research support and digital development so clients can involve us earlier in their product journey.
