About Us
A jewelry manufacturer for brand owners, independent designers and private labels — K gold, 925 silver, brass and copper, made under one roof.
Design and production are in-house: our designers, CAD team, casting, hand stone setting, polishing and plating all sit in the same workshop in Guangdong. Orders start at 30 pieces per design, samples take 7–12 days, and one dedicated contact follows your order from quote to delivery.
Factory Strength
Two dedicated production lines cover rings, necklaces, bracelets and earrings in a 900 m² workshop in Guangdong. Our 50-strong team includes in-house designers, 3 R&D engineers and 8 QC inspectors, with casting, polishing, welding and hand stone setting on site — so quality is checked at every stage, not only on the finished piece.
Every SKU carries an agreed spec sheet: metal and purity, plating thickness, stone setting, dimensions and tolerance. Salt-spray and tarnish testing runs before packing, and a reference sample stays on file so reorders match the original colour and size. That is how consistency is held — not by a claim in a brochure.
For larger programmes, volume runs through long-standing casting and polishing partners in Guangdong — capacity that scales without changing the rules: the same spec sheets, the same QC gates and the same contact from quote to delivery.

K Gold, 925 Silver, Brass & Copper Jewelry ManufacturingOEM & ODM custom manufacturer · MOQ 30 pieces · Worldwide shipping
Our core business is K gold, 925 silver, brass and copper jewelry processing and production. We are a manufacturer and OEM/ODM partner for brand owners, independent designers and private labels — a 900 m² workshop in Guangdong with casting, polishing, hand stone setting and plating under one roof.
Design and production sit in the same building: our own designers and CAD team, in-house casting, hand stone setting, polishing and plating — taste and craft in one workshop, which is what most factories cannot offer.
Ready-to-ship stock is 925 sterling silver; K gold, brass and copper pieces are made to order. Stone setting in cubic zirconia and lab-grown diamonds runs in-house, so brand owners and independent designers can build a whole collection with one supplier.

Buyer questions
The questions buyers ask first
What is your minimum order?
30 pieces per design, and you can split that across sizes and across our metal options: K gold, 925 sterling silver, brass and copper.
Can you work from my sketch or a photo?
Yes. Most projects start from a drawing, a reference photo or a sample you already sell. Our three in-house designers build the CAD, you approve it, then we cut the master.
Do you supply solid gold?
We work in K gold (8K, 9K and 14K), 925 sterling silver, and brass and copper. We do not sell gold-filled, and we do not pass plated base metal off as solid gold.
How long does an order take?
Quote in 48 hours, CAD in 24 to 72 hours, sampling 7 to 12 days, and bulk production 20 to 35 days after the sample is approved.
Do you provide test reports?
Orders can ship with SGS assay, EN 1811 nickel release, GB 11887-2012 and RoHS documentation. Tell us the destination market at quoting stage and we match the paperwork to it.
Can you do private label and custom packaging?
Yes. Your logo, tags and packaging can all carry your brand, and they are quoted together with the piece so the landed cost is clear before you commit.
