The short answer
Both are thin electroplated layers on top of sterling silver, and neither changes what the piece is made of.
- Rhodium is a hard, bright, white platinum-group metal. It gives silver a brilliant white, tarnish-resistant surface.
- Gold plating changes the colour to yellow or rose.
How long either lasts depends far more on thickness, where the piece rubs, and how it is worn than on the metal chosen. Plating on a ring can wear through within months to a couple of years. On earrings and pendants it can last much longer. When it wears, the silver underneath shows and can tarnish again. Plating can be redone. Ask for the thickness in microns, and never use abrasive polish on plated silver.

What electroplating does
Electroplating deposits a thin metal layer from a solution onto a conductive object using an electric current. For jewellery, the sequence is broadly:
- Finish the piece completely, including soldering, setting stones where they can tolerate it, and sizing. Work done after plating damages it.
- Polish. Plating copies the surface beneath it. Scratches and pits show through, so the piece is polished first.
- Clean and degrease thoroughly, so the plating bonds.
- Optional barrier layer. Some platers deposit an intermediate metal, often nickel or palladium, before gold.
- Plate in the rhodium or gold bath.
- Rinse and finish.
The result looks like solid metal, but it is a coating, usually measured in microns (thousandths of a millimetre).
Rhodium and gold compared
| Rhodium plating | Gold plating | |
|---|---|---|
| What it is | A platinum-group metal: hard, corrosion-resistant and highly reflective (Wikipedia: Rhodium) | Gold or a gold alloy, applied as yellow, rose or other shades |
| Colour on silver | Bright, cool white, whiter than bare sterling | Yellow or rose; shade depends on the alloy |
| Main reason to use it | A brilliant, low-tarnish white surface | The look of gold on a silver budget |
| Hardness of the layer | Hard | Softer, especially high-karat gold |
| What you see when it wears | Slightly greyer sterling at rub points, which can then tarnish | Silver-white patches through the gold, which are obvious |
| Typical uses | Silver rings, chains, earrings, stone-set pieces | Fashion silver, vermeil, devotional pendants |
Gold wear is more visible than rhodium wear. A white rhodium layer wearing through to white silver is subtle. A yellow gold layer wearing through to white silver is obvious. This is the main practical difference for daily-wear rings.
The substrate matters
The plating is only as good as the surface beneath it:
- Sterling silver is the usual substrate for both. Because it is 92.5% silver, the piece keeps its metal value when the plating wears.
- Porosity and solder. Castings with tiny pores, or poorly finished solder joints, can let moisture under the plating or show through as dull spots.
- Barrier layers. A nickel interlayer is common in some plating lines. If you have a nickel allergy, ask whether one has been used. In the United States, a sterling piece with a base-metal layer such as nickel under the gold must disclose that before it can be called “vermeil” (16 CFR §23.4). In the UK, the Assay Office says plating precious-metal articles with metals outside the permitted list is not allowed, “whether as an interlayer or a surface layer” (Assay Office).
Thickness: the number that matters most
Plating thickness is rarely printed on Indian listings, and manufacturers’ figures vary widely. A few reference points show what “thick” and “thin” mean:
| Reference | Thickness | Source |
|---|---|---|
| US “gold electroplate” minimum | 0.175 micron of fine gold equivalent | 16 CFR §23.3 |
| US “heavy gold electroplate” minimum | 2.5 microns | 16 CFR §23.3 |
| US “vermeil” (gold on sterling) minimum | 2.5 microns of at least 10K gold | 16 CFR §23.4 |
| UK: plating applied after hallmarking | must not exceed 2 micrometres | Assay Office |
These are US and UK rules, quoted only to show the scale. Indian listings are not bound by the US definitions, and “gold plated” in India does not imply any minimum thickness. Rhodium layers on jewellery are generally thin, and jewellers’ quoted figures range from well under one micron to a little over. Ask the seller or plater for the thickness they apply.
A 2.5 micron gold layer is roughly 14 times thicker than a 0.175 micron one. That difference shows on a ring within weeks or months.
Where plating wears: high-contact surfaces
| Piece | Wears fastest at | Expected life (broad guide) |
|---|---|---|
| Ring | The underside of the band (palm side), the edges, prong tips | Shortest: months to a couple of years for daily wear, depending on thickness and hand use |
| Bracelet | The inside surface, clasp, links | Short to medium |
| Chain | Links rubbing each other, the clasp | Medium |
| Pendant | The back, the bail | Long |
| Earrings | Rarely touched | Longest |
Jewellers who replate rings commonly describe rhodium on a daily-worn ring as lasting one to three years, and less on a dominant hand or with frequent hand-washing (for example, this repair service’s estimate). Treat that as a broad trade estimate, not a guarantee. Gold plating of similar thickness tends to show wear sooner, because the colour difference is visible.
Can silver tarnish under the plating?
Not where the plating is intact and sound. Once the layer is worn, scratched or porous, the exposed silver tarnishes normally, and dark patches can creep from the edges. With rhodium, the first sign is often a slight greyness or yellowing at the rub points. With gold, it is silver-coloured patches that later darken.
Replating: cost and practicalities
Replating is routine, but it involves more than “dipping”:
- The piece is cleaned and polished again, which removes a little silver each time.
- Stones that cannot tolerate the plating bath or heat, such as pearls, coral, opal, turquoise, emerald and other porous or treated stones, may need to be removed or protected first. Our silver care guide covers stone-set silver.
- The cost is mostly labour and the plating metal. Rhodium is an expensive metal, so rhodium replating is not necessarily cheaper than gold.
- Frequency: replate when the colour change bothers you. For a daily ring, that may be every year or two. For earrings, perhaps never.
Cleaning rules for plated silver
- Do wipe with a soft, lint-free cloth after wearing.
- Do wash in lukewarm water with a drop of mild soap, rinse, and dry at once.
- Don’t use silver polishing cloths, dips or polishes. They are designed to remove tarnish and a thin layer of metal, and they will strip plating.
- Don’t use toothpaste, baking soda or abrasive powders.
- Don’t wear plated pieces in chlorinated pools, hot tubs or the sea, or while using cleaning chemicals.
- Do put the piece on after perfume, lotion and hairspray.
- Do store it separately so harder items cannot scratch the layer.
Is plated silver waterproof? Plating is not a seal. Occasional water does no harm, but frequent wetting with soap, sweat and chlorine speeds wear, and moisture reaches the silver wherever the layer is broken.
Allergies and metal composition
- Rhodium itself rarely causes problems for most people, and rhodium plating is sometimes used over white gold for its white surface.
- Barrier layers may contain nickel. If you have a nickel allergy, ask whether a nickel interlayer was used.
- As plating wears, the skin touches whatever is underneath: sterling silver in a sterling piece, but brass or another base metal in a cheaper plated item.
This is general information, not medical advice. If you react to jewellery, consult a doctor.
Does rhodium change silver purity?
No. Plating adds a thin surface layer and does not change the alloy underneath. A rhodium-plated 925 ring is still 925 silver. Under India’s silver hallmarking scheme, the hallmark refers to the silver article’s purity. Ask a plater not to polish through or damage the hallmark when replating.
Questions to ask the jeweller
- What is the base metal, and is it hallmarked (BIS, with a HUID)?
- Rhodium or gold? If gold, what karat and what colour?
- How thick is the plating, in microns?
- Is there a barrier layer, and what metal is it?
- Were stones set before or after plating, and which stones are sensitive?
- What is the replating policy and cost, and is replating included for a period?
- How should I clean it, and what should I avoid?
Example: plating offered as an option
Some sellers offer plating on sterling pieces at the customer’s choice. GemKrishna’s listing for a 925 sterling silver, BIS-hallmarked pendant (22.73 g, antique oxidised finish) states that gold or rhodium plating is available on request (listing, checked 9 October 2026). The listing does not give a plating thickness, so ask for it, as you would anywhere. Note that plating an oxidised piece changes its deliberately darkened finish.
Decision guide
| If you want… | Choose |
|---|---|
| A bright white silver ring that resists tarnish | Rhodium-plated 925, accepting periodic replating |
| The look of yellow gold on silver for occasional wear | Gold-plated 925, ideally a thicker layer |
| Gold colour on a ring worn every day | Consider gold jewellery instead; a thin gold plate will show wear quickly. See our gold jewellery guide |
| A traditional look with no maintenance | Unplated 925, cleaned as it tarnishes |
| An oxidised, antique finish | Unplated oxidised 925; avoid plating, which hides the effect |
FAQ
Which lasts longer, rhodium or gold plating?
At similar thickness, rhodium is harder and its wear is less visible, so it usually looks good for longer on silver. In practice, thickness and where the piece is worn matter more than the metal. A thick gold layer on a pendant can outlast a thin rhodium layer on a ring.
Can silver still tarnish beneath plating?
Only where the plating is worn, scratched or porous. Intact plating protects the silver. Once it wears, the exposed silver tarnishes normally.
Is plated silver waterproof?
No. Plating is a thin coating, not a seal. Occasional contact with water is fine, but frequent washing, swimming and chlorine accelerate wear.
How often should I replate?
When the colour change bothers you. A daily-worn ring may need it every year or two. Pendants and earrings, much less often. Replating also involves polishing, which removes a little silver each time.
Does rhodium plating change the purity of 925 silver?
No. The underlying alloy is unchanged. A rhodium-plated sterling piece is still 925 silver.
Is 24K gold plating more durable than lower-karat plating?
Not necessarily. Pure gold is softer than gold alloys. What matters most is the thickness of the layer and how the piece is worn. Ask for the thickness rather than relying on the karat.
Is gold-plated silver the same as vermeil?
In the US, “vermeil” has a legal definition: sterling silver with at least 2.5 microns of at least 10K gold. In India, there is no equivalent legal definition, so ask for the karat and thickness rather than relying on the word.
