Our Manufacturing Capabilities
Our factory floor covers the full production chain for sterling silver and brass jewelry, set with moissanite, lab grown diamonds, semi-precious stones, cultured pearls and cubic zirconia. Because wax injection, casting, setting, polishing and plating all happen under one roof, we can hold tight tolerances and keep lead times predictable.
• Over 3,000 active designs already tooled and ready to order
• Cutting out the trading layer typically saves buyers up to 40%
• Every finished piece is checked individually before packing
• Thirty-day satisfaction guarantee on every production order

Why Partner With Us
HOLYCOME JEWELRY is a Wuzhou-based manufacturer of moissanite, lab grown diamond and sterling silver jewelry, working directly with brands, wholesalers and online retailers worldwide.
We handle both OEM production from your drawings and ODM development where our design team proposes the collection for you — whichever suits your stage of business.
Eighteen years inside the jewelry supply chain means we already know the pitfalls: stone matching, plating thickness, clasp durability, sizing consistency.
Our production lines cover sterling silver and brass with gold plating, serving more than one hundred active customers across North America, Europe, the Middle East and Australia.
Every batch passes a four-stage quality process before it ships. Because you buy straight from our factory there is no trading company margin, and each order is backed by a thirty-day satisfaction guarantee.

Brands We Work With
How We Control Quality
Four dedicated checkpoints sit between raw material and your parcel, so problems surface at the bench rather than in your warehouse. Every order you receive is measured against the specification you approved at sampling.
Moulds are cut from a 3D model built by our designers in JewelCAD. The team averages over ten years of CAD experience, so the finished casting matches the approved rendering. Each mould is verified against the drawing before it reaches the production line.

Full Final Inspection
Every piece of your jewelry is subjected to a 100% inspection to ensure its adherence to the exacting standards of high quality fine jewelry, and any defective products are promptly eliminated.
What Our Clients Say
Michael Donovan
Founder & CEO — Aurora Fine Jewels, USA
We have been sourcing moissanite and lab grown diamond jewelry from Holycome Jewelry since 2017, and they remain our most dependable partner in Asia.
Their in-house wax injection, casting and stone setting let them hold tight tolerances on every run, and the 100% inspection before packing means we almost never see a return.
Order volumes have grown more than three times over the past eight years, and their factory-direct pricing keeps our retail margins healthy. I recommend them without hesitation to any brand that needs a long-term, trustworthy manufacturing partner.
Daniel Fischer
Head of Product — Nordlicht Jewellery, Germany
Working with Holycome has been refreshingly straightforward from day one.
The development team turned our sketches into production-ready 3D files in under a week, and the first samples arrived within seven days — well ahead of the schedule we had planned for.
Because we deal directly with the factory there is no middle layer, so quotation, tooling changes and delivery dates are all handled quickly and transparently. Our collection has doubled in size and sell-through is up around 150% year on year.
