PVD vs gold plating: which finish fits your jewelry line
The short answer: PVD coatings are typically harder and more wear-resistant than electroplated (galvanic) coatings, which makes them a strong choice for jewelry that sees daily friction [S2]. Electroplating deposits actual gold or gold alloy, and that matters if your product claims gold content [S1]. Neither process is better in every case [S2]. The right choice depends on your product, your base metal, and what you plan to say on the label.
The short answer, in a table
| Comparison criterion | PVD / IP coating | Gold electroplating |
|---|---|---|
| How it is applied | Vapor deposition in a vacuum [S2] | Electrolytic process in a bath [S1] |
| What is deposited | Often a ceramic such as titanium nitride; gold-tone TiN is a common decorative finish [S2] | Gold or gold alloy [S1] |
| Wear resistance | Typically harder and more wear-resistant [S2] | Typically softer than PVD [S2] |
| How it can be described in the US | Not "gold electroplate", which is reserved for electrolytic gold plating [S1] | "Gold electroplate" when the karat fineness is stated and the plating has reasonable durability [S1] |
Both processes have advantages and limitations, and the industry increasingly combines them to widen the colour range and textures available [S2].
How each process works
Electroplating
Electroplating, also called galvanic plating, uses an electrolytic process to deposit a metal layer onto the part, using plating baths [S1][S2]. For gold jewelry, that layer is gold or a gold alloy [S1]. Electroplating long dominated decorative finishing in fashion, before PVD gained ground [S2]. Some traditional galvanic baths, including those based on hexavalent chromium and cyanide, face restrictions in the European Union, which is one reason the decorative industry has been moving toward PVD [S2].
PVD and IP plating
PVD (physical vapor deposition) builds a thin film from vaporized material inside a vacuum chamber [S2]. At Northmelon, we call our vacuum PVD process IP, or ion plating. Particles travel in a "line-of-sight" path from the source to the part, which gives PVD films their typical columnar structure, often with some porosity [S2]. That is one reason surface preparation and coating design matter so much.
For gold colours, a common route is titanium nitride (TiN), a hard ceramic that can be tuned to golden shades [S2]. Replicating golden coatings with TiN PVD proved a cost-effective decorative solution [S2]. Watchmakers developed an earlier version of this process: a thin layer of titanium nitride covered with a flash of gold, to create a highly wear-resistant gold finish [S2].
Durability in real wear
PVD's main advantage is hardness and wear resistance [S2], so it is a natural fit for pieces that rub against skin, clothing and other surfaces all day, such as rings, bracelets and chains. Electroplated finishes can be a good fit where the gold content itself is the selling point, or where the piece sees less friction.
Real-world performance always depends on more than the process name. It depends on the base metal, the surface preparation, the coating build and the way the piece is worn. Wearable products are commonly checked with standard tests such as the neutral salt spray test (ISO 9227) and the synthetic sweat test (ISO 3160-2) [S2]. When a supplier talks about durability, ask which tests were run and for which market.
Avoid selling any finish as permanent. Instead, ask your manufacturer for lab reports for your market before you print durability claims.
Which finish to choose, by product and goal
These are our recommendations for buyers, not industry rules.
| Your goal | Usually start with |
|---|---|
| Daily-wear stainless steel rings, bracelets and chains | PVD / IP on stainless steel |
| Gold-tone look at a fashion price, with good wear | PVD / IP on stainless steel |
| A product that claims karat gold content | Gold electroplating, labelled with its karat fineness |
| Copper alloy pieces that need real gold on the surface | Gold electroplating on copper alloy |
| A very wide colour range or special textures | Ask your supplier whether a combined approach is possible [S2] |
| Black, rose or two-tone stainless steel styles | PVD / IP on stainless steel |
If you are unsure, sample both on the same design and wear-test them yourself, alongside lab reports for your market.
How to describe the finish honestly
How you name a finish can matter as much as the finish itself. For products sold in the United States, the FTC's Guides for the Jewelry, Precious Metals, and Pewter Industries (16 CFR Part 23) give clear direction [S1]:
- Do not misrepresent gold. It is unfair or deceptive to misrepresent the presence of gold, its karat fineness, or the thickness or manner of application of any gold plating or coating [S1].
- Qualify the word "gold". Using "Gold" without qualification for a product that is not fine (24 karat) gold throughout may mislead [S1]. For a surface-plated product, the word "Gold" should be qualified to show the product is only surface-plated [S1].
- "Gold plate" and "gold plated" need real gold alloy. These terms should be used only when the product has a surface plating of gold alloy, applied by any process, that gives reasonable durability. The karat fineness must come immediately before the term [S1].
- "Gold electroplate" means electrolytic plating. The term should be used only when the product is electroplated with gold or gold alloy, with the karat fineness stated immediately before it [S1].
- Do not borrow a better product's name. Using terms that misrepresent a product as equal or superior to an established type of product, with reference to gold content or method of manufacture, may mislead [S1].
What this means in practice: if a PVD finish contains no gold alloy, describe it as a colour, for example "gold-tone", rather than as "gold plated". If you use a karat number to name a shade, such as "18K gold-tone", make it clear that it describes the colour, not gold content. If a piece really is electroplated with gold or gold alloy, "gold electroplate" can apply, with the karat fineness stated immediately before the term [S1]. Confirm the plating details with your manufacturer before you print it. Check final label wording with your own legal adviser for each market. Rules outside the US differ.
The same care applies to "waterproof" and "hypoallergenic". Use them only when lab reports for your market support them.
What to put in your quote request
A clear request gets you comparable quotes and fewer surprises at sample stage:
- Base material and grade: for stainless steel, say 304, 316 or 316L, or ask the supplier to recommend one
- Process: PVD / IP, karat gold plating, or "please recommend"
- Finish colour and reference: a physical sample is the most reliable reference
- High-friction areas: which parts of the piece rub the most
- Target market: so the right lab reports can be planned
- Planned claims and label wording: for example "18K gold-tone", or "gold electroplate" with its karat fineness
- Testing: ask which tests are available, such as salt spray or synthetic sweat, and request reports for your market
How Northmelon handles plating
Stainless steel is our main material. Northmelon plates stainless steel jewelry on its own licensed vacuum IP / PVD line, inside our 40,000+ m² park in Dabu County, Meizhou. Steel parts are plasma polished before plating. Our stainless steel finishes are steel, 18K gold-tone, 14K gold-tone, rose gold-tone, black and two-tone. These names describe the colour, not gold content.
For copper alloy pieces, which supplement our stainless steel range, we also offer real gold electroplate. Tell us the design and target market, and we will confirm the options before sampling.
We have an in-house salt-spray testing machine, and salt-spray testing is available on request. THIRD-PARTY TESTING / Lab reports for your market, on request.
MOQ is 200 pieces per style. Samples take 12 working days after specs are confirmed. Standard bulk production takes 45 days, counted from the day after order confirmation.

Frequently asked questions
These answers summarise the sourced sections above [S1][S2].
Which lasts longer on stainless steel jewelry, PVD or gold plating?
PVD coatings are typically harder and more wear-resistant than electroplated coatings, but real-world life also depends on surface preparation, coating build and how the piece is worn. Neither finish should be sold as permanent. Ask your manufacturer for lab reports for your market before making durability claims.
Is PVD gold real gold?
Not necessarily. A gold-tone PVD finish can be made from titanium nitride, a ceramic tuned to a golden shade, sometimes with a thin flash of gold on top. Electroplated gold deposits gold or gold alloy. Describe the finish accurately, for example as gold-tone, and confirm the layer system with your manufacturer.
Can I call PVD jewelry "gold plated"?
In the US, the FTC Jewelry Guides say "gold plated" should describe a surface plating of gold alloy, applied by any process, with reasonable durability and the karat fineness stated. If a PVD finish contains no gold alloy, describe it as a colour instead. Check final wording with your legal adviser.
What should I specify when asking a factory to quote PVD plated jewelry?
State the base material and grade (304, 316 or 316L), the finish colour, a colour reference, your target market, quantity per style and any claims you plan to print. At Northmelon, MOQ is 200 pieces per style, samples take 12 working days, and lab reports for your market are available on request.
Does Northmelon offer real gold plating?
Yes, on copper alloy. Stainless steel is Northmelon's main material, and it is finished on an in-house vacuum IP / PVD line in colours such as 18K gold-tone. Copper alloy pieces can be given real gold electroplate. Options are confirmed for each design, and lab reports for your market are available on request.
