Buyers who have walked a factory floor buy with more confidence and argue less about specification, because they have seen what the process can and cannot hold. We welcome visits from trade buyers and accept customer-commissioned third-party audits.
Arranging a visit
| Item | Detail |
|---|---|
| Location | Wuzhou, Guangxi, China, the gemstone and synthetic stone manufacturing centre |
| Nearest airports | Wuzhou Xijiang Airport, or Guangzhou Baiyun plus about 2.5 hours by high-speed rail |
| Notice required | At least 5 working days, so we can schedule a production line for your category |
| Best days | Monday to Friday, 09:00 to 16:00; Saturday mornings by arrangement |
| Duration | Half a day for a production walkthrough; a full day to include sampling and technical discussion |
| Languages | An English-speaking merchandiser is assigned for the visit |
| What to bring | Your specification list, any reference samples, and the SKUs you want to discuss |
What you will see, station by station
- Stone intake and grading. Where parcels are checked for colour, clarity and measurement against the order sheet, and where out-of-tolerance stones are rejected before they reach the setting line.
- Stone and melee storage. Calibrated melee sorted by size and grade in labelled sealed parcels. This is the station buyers find most reassuring, because unlabelled loose stones are the clearest sign of a disorganised operation.
- Wax printing and CAD. Where your custom design becomes a printable model, and where revisions are made before a mould is cut.
- Casting. The investment casting line, including the gold casting area and its separate metal handling controls.
- Setting benches. The production bottleneck and the best indicator of real capacity. Count the benches and ask how many setters work each day.
- Filing and polishing. Where the finish is produced, including the inner-shank polish that separates careful factories from fast ones.
- Plating line. Rhodium and gold plating tanks or barrels, with thickness control and the test method used to verify it.
- QC station. 10x loupe inspection, calibrated scale, calipers, and the written inspection sheet used per piece.
- Packing and dispatch. Individual bagging, carton photography before sealing, and the document pack prepared per shipment.
What we prepare for a visiting buyer
| Document | Purpose |
|---|---|
| Business licence and export registration | Confirms the legal entity you are contracting with |
| Approval sheet template | Shows the specification format used for every order |
| Master sample set for your category | Physical reference for the grades you are considering |
| Recent grading reports | IGI, GRA or NGTC reports with our name as submitter |
| Material declaration template | The document that accompanies every export shipment |
| Production capacity statement | Monthly capacity by product type, and current line loading |
Sampling during a visit
If you bring a specification or a reference piece, we can often produce a wax or a first-off casting during a full-day visit, so you leave with something physical to evaluate. Bring stone specifications in advance if you want the exact stone set rather than a substitute, because matched stones for a specific size and grade may need to be pulled from stock.
Remote audits
Most buyers cannot travel. For those, we offer a structured remote audit rather than a highlight video.
- A live video call, not a pre-recorded clip, walking the floor in the sequence above in one continuous session.
- A second call focused on the QC station, with a piece inspected on camera against its specification sheet.
- A documentation pack sent by email before the call, so you can question specific documents live.
- A named merchandiser as your ongoing contact, who is the person on camera rather than a sales representative reading from a script.
Third-party inspection agencies are welcome. We coordinate access, provide the documentation they request, and do not restrict which areas they photograph. If an inspector is appointed for a pre-shipment inspection, we schedule the goods for inspection before packing and hold the dispatch date until the report is issued.
What a visit will not change
A factory tour is evidence of capability, not a substitute for written terms. Visitors sometimes leave reassured and then place an order without an approval sheet, which is the single most common cause of the disputes we mediate. The visit and the paperwork do different jobs: the visit tells you whether the capability is real, and the approval sheet tells you what you will receive.
To arrange a visit or a remote audit, contact our trade desk with your intended dates and product categories, and we will confirm a schedule and assign a merchandiser.
