Wuzhou · Guangxi · China
A jewelry factory, not a trading desk
HOLYCOME runs design, casting, setting, polishing, plating and QC on one floor. That is why a change requested on Monday can be cast on Wednesday — and why we can tell you the exact bath your order was plated in.
Figures describe the Wuzhou HengliLai Jewelry Co., Ltd. production floor and are stated as registered, not as marketing estimates.






What each station actually does
Six stations, described by the work that passes through them rather than by the machine model on the floor.
| Station | Equipment | What it means for your order |
|---|---|---|
| Casting | Induction gold line + vacuum silver line | Both metals cast in-house; flasks logged per batch |
| CAD | Rhino / Matrix workstations | Two render revisions included per new build |
| Stone setting | Prong, bezel, pavé, channel, invisible | Microscope setting for mezzanine melee work |
| Polishing | Four-stage abrasive + ultrasonic | Pre-polish before setting, final polish after |
| Plating | Rhodium, 18K gold, rose gold, black rhodium | Bath parameters logged for repeatability |
| QC | Loupe and microscope stations | Every piece checked against the signed spec sheet |
Visit the floor
Buyers are welcome in Wuzhou
The workshop is in the Jewelry E-Commerce Building in Wuzhou, about two hours by high-speed rail from Guangzhou. Buyers who visit usually spend the morning on the floor and the afternoon on spec sheets — it is faster than six rounds of email.
If a trip is not practical, we run a video walkthrough of the bench handling your order, including the stones that will be set.

What we do not claim
Buyer due diligence is easier when a factory states its boundaries. We do not grow moissanite or lab-grown diamond rough — that comes from specialist growers, and independent grading is issued by GRA or IGI rather than by us. We do not publish an ISO 9001 number because the entity holds material-test and social-audit reports instead, and those are the documents our buyers actually ask for.
What we do control is the metal, the setting, the plating and the inspection. Those are the four places a jewelry order usually goes wrong, and they are the four places this floor owns end to end.
Factory questions
How many pieces can you produce per month?
The floor runs several thousand pieces a month across silver and gold lines, with capacity reserved for repeat buyers. Large programmes are scheduled in writing before the first cast.
Do you accept buyer audits?
Yes. Social-compliance and material-test documentation is available, and buyers with their own audit programme are scheduled in advance.
Is the factory owned or subcontracted?
Owned and operated by Wuzhou HengliLai Jewelry Co., Ltd., the same legal entity that invoices your order.
