Read our dedicated Jewelry Materials Guide and Plating & Finish Guide.
Choose the Right Material and Plating for Your Market
Compare stainless steel, brass and 925 sterling silver together with PVD, electroplating, gold thickness and underlayer options.
The Base Metal and Surface System Work Together
Material affects strength, weight, forming, casting, stone setting, price and customer positioning. The finishing route then affects color, surface appearance, wear expectations and care instructions.
For accurate quotations, confirm the base metal and the complete layer structure rather than requesting only “gold plated jewelry.”
Four Starting Points for Product Development
Select the material around construction, finish, price point and end-customer expectations.
304 stainless steel
A practical option for many fashion-jewelry components and price-sensitive stainless steel collections.
316L stainless steel
Preferred for many durable, corrosion-resistant and skin-contact jewelry programs, including waterproof-positioned PVD collections.
Brass
Well suited to detailed casting, forming, stone setting and flexible electroplating specifications.
925 sterling silver
A precious-metal option for higher-value positioning, detailed designs and rhodium or gold plated finishes.
Compare Base Materials Before Sampling
The most suitable material depends on construction and commercial positioning, not one universal “best” choice.
| Material | Best suited to | Key advantages | Points to confirm |
|---|---|---|---|
| 304 stainless steel | Fashion jewelry, chains and components | Strong, stable and economical | Grade, welding, polishing and finish route |
| 316L stainless steel | Water-resistant positioning and frequent-wear styles | High corrosion resistance and strong PVD compatibility | Exact grade, construction and coating specification |
| Brass | Detailed shapes, statement pieces and stone-set designs | Flexible forming, casting and electroplating | Underlayer, gold thickness, skin-contact requirements and care |
| 925 sterling silver | Precious-metal collections and fine-detail designs | Recognized material value and versatile finishing | 925 marking, weight, anti-tarnish or rhodium/gold finish |
A Layer Structure Designed for Durable Gold Plated Steel Jewelry
HonHo stainless steel PVD programs can use a 0.5 μm TiN interlayer with a 0.03–0.10 μm gold-color layer. The final route is selected around color, construction, wear expectation, target cost and required testing.

Specify Gold Thickness Around Price and Wear Expectations
Standard in-stock brass products can use approximately 0.03 μm gold plating. Custom projects can be specified from 0.03 to 2.5 μm, with thicker routes reviewed separately. An optional palladium underlayer can be added to improve barrier performance and support longer wear.

PVD, Electroplating and Underlayer Options
Finish names alone are not enough. Confirm the base metal, preparation, underlayer and final layer thickness.
| Finish route | Typical base | Specification focus | Buyer consideration |
|---|---|---|---|
| PVD | 304/316L stainless steel | TiN support layer, final color layer and process control | Durable option for frequent-wear and waterproof-positioned collections |
| Standard gold electroplating | Brass or 925 silver | Surface preparation and approximately 0.03 μm gold layer | Commercial price point; requires appropriate care instructions |
| Thicker gold electroplating | Brass or 925 silver | Custom gold thickness up to 2.5 μm as quoted | Higher cost with improved wear potential |
| Palladium underlayer | Brass or 925 silver | Barrier layer below the final finish | Can improve isolation and support longer finish life |
| Rhodium or white finish | 925 silver or brass | Brightness, color target and layer structure | Confirm whether a barrier or anti-tarnish route is required |
Common Technical Questions From Jewelry Buyers
Use the answers below to prepare a clearer RFQ and product-care statement.
Is 316L always better than 304 stainless steel?
316L generally offers higher corrosion resistance, but the right choice also depends on construction, target price, forming, welding and the finish route.
What does the TiN interlayer do?
A TiN interlayer supports the PVD layer system on stainless steel and helps create a more durable barrier and consistent finish when the process is correctly controlled.
How thick is HonHo’s stainless steel PVD gold layer?
Custom stainless steel programs can use a 0.03–0.10 μm PVD gold-color layer with a 0.5 μm TiN interlayer option. Final specifications are confirmed by project.
How thick is standard brass gold plating?
Standard in-stock brass products can use approximately 0.03 μm gold plating. Custom thicknesses can be quoted up to 2.5 μm, with thicker requests reviewed separately.
Why add a palladium underlayer?
Palladium can act as a barrier layer between the base metal and final finish, supporting isolation, surface stability and longer wear potential.
Can PVD be applied to brass or 925 silver?
Yes, selected PVD routes can be developed for brass or 925 silver, but the preparation and process must be matched to the base material and design.
Does waterproof mean the jewelry never needs care?
No. Water resistance describes the product system under expected use; chemicals, abrasion, storage and repeated exposure still affect appearance and wear.
Can HonHo support REACH nickel and California Proposition 65 requirements?
Material, plating and testing routes can be planned around buyer requirements. The exact standard and test scope must be confirmed before sampling.
