Precision Gold Plating Solutions for Global Jewelry Brands
High-performance PVD and electroplating services for stainless steel and brass. Scalable OEM/ODM manufacturing with 20+ years of export excellence.
Addressing Typical Challenges in Gold Plating Jewelry
Inconsistent Plating Thickness
Each product undergoes pre‑ and post‑plating inspections using X‑ray fluorescence thickness gauging (≥0.08μm), minimizing variation across batches.
Tarnishing & Quality Failures
We conduct 72-hour salt spray, 500-cycle wear resistance, over 1.5-kilogram tensile strength, and 300-cycle rolling test to verify products’ color retention and durability before packaging.
Unpredictable Lead Times
With a transparent production system and advanced management standards, we ensure a 97% on-time delivery rate. You can track the production progress and order status in real-time.
Insufficient Quality Documentation
We provide 100% traceable compliance reports for REACH, RoHS, SGS, ISO, and RIC, backed by a 15-year archived database of material and testing records for every batch.
Our Gold Plating Process
As an expert custom gold-plated jewelry manufacturer, we treat every step as a critical point of failure that must be managed.
How our gold plating process delivers consistency:
1. Raw Material Inspection
Before gold plating begins, we inspect the base metal (stainless steel or brass) for surface stains and impurities that could interfere with the adhesion of the gold layer.
2. Surface Preparation
The jewelry undergoes ultrasonic cleaning and polishing to remove oils and dust, as well as a mild acid bath to remove surface oxides. These guarantee the gold will bond firmly to the metal.
3. Base Layer Application
We apply a high-quality base layer to improve the brightness of the final finish and act as a barrier to prevent the base metal from migrating into the gold layer, preventing premature tarnishing.
4. Plating Application
Using electroplating and PVD systems, gold layers are deposited with precise thickness control. Whether it is 14K or 18K, our technicians monitor the process to ensure color consistency.
5. Post-Treatment
After plating, pieces are rinsed and treated with an anti-tarnish coating if required. Every batch undergoes a final visual and technical inspection to verify thickness and color.
“We strictly control the entire production process to ensure consistent jewelry quality.”

I kärnan av vår verksamhet finns en kundcentrerad strategi. Vi tar oss tid att förstå dina unika behov och samarbeta nära med dig för att leverera skräddarsydda smyckeslösningar som perfekt överensstämmer med ditt varumärke. Som mer än bara en leverantör är vi en pålitlig partner, engagerad i att driva värde och framgång för ditt smyckesföretag.
“Vi har arbetat med StarHarvest i över 3 år och deras kvalitetskontroll är felfri. I vår senaste beställning av 50 000 bitar hade deras rostfria stålkedja en defektnivå på mindre än 0.5%. Det som imponerade mest på oss var att de proaktivt tillhandahöll en rapport om beläggningens tjocklek före leverans – precis den typ av noggrannhet vi behöver.”
“Deras materialcertifieringssystem är grundligt. Varje mässingslegeringsbatch kommer med milltestrapporter som visar exakt sammansättning. När vi begärde dokumentation för blyfri överensstämmelse för EU-marknaden, tillhandahöll de fullständiga testrapporter inom 12 timmar. Denna nivå av professionalism är sällsynt.”
“Star Harvests responsivitet räddade oss en stor semesterproduktion. När vi behövde en sista minuten-modifikation av en rostfri stålpendel, hade deras ingenjörsteam CAD-justeringar redo inom 6 timmar. Deras provnoggrannhet innebär att vi nu kan hoppa över prototyper—den första batchen är 95% produktionsklar.”
Gold Plating Cases
A glimpse into our manufacturing versatility.
/01
What plating thicknesses are available?
What plating thicknesses are available?
We offer a full range from 0.1μm to 5.0μm+, customized by product use.
- 1-0.3μm (color retention for 3-6 months) is commonly used for fast-fashion items, suitable for e-commerce startups.
- 5-1.0μm (color retention for 1-2 years) balances performance and cost, making it ideal for rapidly growing brands that are optimizing their supply chains.
- 5-2.0μm (color retention for 3-5 years) involves a slight increase in cost but offers enhanced durability. It helps reduce returns and build brand trust.
- 0μm+ (color retention for over 5 years) is recommended for North American/European brands that prioritize long-term quality.

Typical lead time for mid-size orders?
Typical lead time for mid-size orders?
Our standard production cycle is 25-35 days. We offer expedited service during the proofing stage (completed within 7 working days). During peak periods of mass production, we utilize an intelligent order scheduling system to ensure delivery timelines.
/03
Can you gold plate complex or intricate jewelry designs?
Can you gold plate complex or intricate jewelry designs?
Yes. Our PVD and advanced electroplating techniques are designed for maximum “throwing power,” meaning the gold ions can reach into deep recesses, intricate filigree work, and complex 3D shapes.

Kan ni tillhandahålla efterlevnadscertifiering för den europeiska och amerikanska marknaden?
Kan ni tillhandahålla efterlevnadscertifiering för den europeiska och amerikanska marknaden?
We provide international test reports compliant with SGS, LFGB, and other standards to meet the requirements of REACH and CPSC regulations. We can also offer customized testing based on specific requirements, such as California Proposition 65.

Stöder ni designkonfidentialitetsavtal?
Stöder ni designkonfidentialitetsavtal?
We work with many high-profile brands and take intellectual property seriously. The entire production process is signed with an NDA confidentiality agreement, and an independent production line is used for closed operation. Design documents are only delivered to the customer upon completion of the order.
