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.

The Workflow

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.”

James Carter
Responsable des achats

“Nous travaillons avec StarHarvest depuis plus de 3 ans et leur contrôle qualité est impeccable. Dans notre récente commande de 50 000 pièces, leur chaîne en acier inoxydable avait un taux de défaut de moins de 0,5%. Ce qui nous a le plus impressionnés, c'est qu'ils ont proactivement fourni un rapport sur l'épaisseur du plaquage avant expédition – exactement le genre de diligence dont nous avons besoin.”

David Kim
VP

“Leur système de certification des matériaux est complet. Chaque lot d'alliage de laiton est accompagné de rapports d'essai en usine montrant la composition exacte. Lorsque nous avons demandé des documents de conformité sans plomb pour le marché de l'UE, ils ont fourni des rapports d'essai complets en 12 heures. Ce niveau de professionnalisme est rare.”

Emma Rodriguez
Développeuse de Produit

“La réactivité de Star Harvest a sauvé notre production majeure pour les vacances. Lorsque nous avons eu besoin d'une modification de dernière minute pour un pendentif en acier inoxydable, leur équipe d'ingénierie avait des ajustements CAO prêts en 6 heures. Leur précision d'échantillonnage signifie que nous pouvons maintenant sauter la phase de prototypage—le premier lot est prêt pour la production 95%.”

FAQ
/01
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.

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.

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.

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.

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.
