Does Jewellery Tarnish? Brand-by-Brand Care Guide
Whether jewellery tarnishes depends entirely on what it is made from. Sterling silver tarnishes within weeks if left unprotected. Brass-based plated jewellery tarnishes when the coating wears through. Stainless steel does not tarnish at all. Gold tarnishes so slowly it is measured in years, not months. This guide covers every material we sell — brand by brand — so you know exactly what to expect, how to prevent tarnish, and how to reverse it when it happens.
We are authorised stockists for every brand in this guide. We sell it, we handle it daily, and we advise customers on care in store. These are not manufacturer talking points — this is what we see across thousands of pieces.
Why Does Jewellery Tarnish?
Tarnish is a thin layer of metal sulfide that forms on the surface of certain metals when they react with sulfur compounds in the air. On silver, this compound is silver sulfide (Ag₂S). On copper and brass, it is copper sulfide. The reaction is purely surface-level — it does not weaken or damage the metal underneath.
The speed of tarnishing depends on two factors: the metal itself and what it is exposed to. Sterling silver (925) contains 7.5% copper, which makes it more reactive than pure silver. Brass (a copper-zinc alloy) is more reactive still. Gold at 18 carats or above is effectively inert under normal conditions. Stainless steel does not tarnish at all.
The Chemistry
- Reaction: Hydrogen sulfide (H₂S) in the atmosphere reacts with silver to form silver sulfide (Ag₂S) — a dark surface film
- Oxidation: Copper content in alloys also oxidises, producing green copper carbonate (verdigris) in some conditions
- Depth: Surface only — the metal beneath remains structurally intact
- Reversibility: Tarnish can be chemically reversed (baking soda method) or physically removed (polishing)
What Accelerates Tarnish
These are the most common accelerators, listed by how frequently we see them cause problems in store:
Perfume & Cosmetics
Alcohol, sulfur compounds, and acids in perfume, hairspray, moisturisers, hand cream, and sunscreen react directly with silver and plating. The single biggest cause of premature tarnish we see.
Hand Sanitiser
Alcohol-based sanitisers strip plating and accelerate tarnish on silver. Rings and bracelets are particularly vulnerable because they sit in the application zone. This became a significant issue post-2020.
Humidity & Moisture
Showering, swimming, sweat, and high humidity all speed up the sulfide reaction. Bathrooms are the worst storage location for jewellery. Chlorinated pool water is especially aggressive.
Household Chemicals
Bleach, washing-up liquid, cleaning sprays, and chlorine react aggressively with silver and strip plated finishes. Remove jewellery before cleaning.
Sulfur-Rich Environments
Rubber bands, certain foods (eggs, onions), wool, leather, and some adhesives release sulfur compounds that accelerate tarnishing even in storage.
Body Chemistry
Acidic skin pH, medications, and diet can affect tarnish rate. Some people tarnish silver noticeably faster than others — this is normal and not a quality issue.
Does ChloBo Jewellery Tarnish?
Yes. ChloBo is made from genuine 925 sterling silver (92.5% silver, 7.5% copper), hallmarked in the UK. All sterling silver tarnishes — this is a feature of the metal, not a fault with the brand. Tarnish risk for ChloBo is moderate: without care, new pieces can develop a visible dullness within the first few weeks if exposed to perfume, hand cream, or humidity.
| Range | Metal | Tarnish Risk |
|---|---|---|
| Sterling Silver | 925 silver (92.5% Ag, 7.5% Cu) | Moderate — weeks to months without care |
| Gold Plated | 925 silver base + 18k gold plating | Lower — gold layer protects but wears over time |
| Rose Gold Plated | 925 silver base + rose gold plating | Lower — same protection as gold plated |
ChloBo-Specific Care Considerations
Elastic bracelets: ChloBo's stretch bracelet format introduces a risk that other silver brands do not have. The elastic weakens with repeated water exposure. Removing stretch bracelets before showering, swimming, or exercising protects both the silver and the elastic. Rigid bangles are more suitable for overnight wear.
Semi-precious stones and pearls: Many ChloBo pieces feature natural stones and freshwater pearls. Never soak stone or pearl bracelets for extended periods. Clean the silver sections only, and wipe stones with a damp cloth. Do not use ultrasonic cleaners on any ChloBo piece with stones, pearls, or elastic.
Green skin marks: The copper content (7.5%) in sterling silver can react with acidic skin chemistry to produce copper salts, leaving a harmless green mark on the skin. This is more common in warm weather or when moisturiser has been applied before wearing. It washes off easily and does not indicate poor quality.
Charm crevices: The detailed charms on ChloBo pieces accumulate tarnish in crevices faster than flat surfaces. A soft-bristled toothbrush helps reach these areas during cleaning.

Does Clogau Jewellery Tarnish?
It depends on which metal you are looking at. Clogau is more complex than most jewellery brands because a single piece often combines multiple metals: 9ct gold, 18ct gold, rose gold, and 925 sterling silver in the same design. Each metal behaves differently over time.
| Metal | Composition | Tarnish Resistance |
|---|---|---|
| 18ct Yellow Gold (750) | 75% pure gold | Excellent — can maintain appearance for decades |
| 9ct Yellow Gold (375) | 37.5% pure gold, balance silver & copper | Very good — slight patina over years, not weeks |
| Rose Gold | Higher copper content than yellow gold | Good — may deepen in tone gradually over years |
| Sterling Silver (925) | 92.5% silver, 7.5% copper | Moderate — tarnishes in weeks to months |
Two-Tone Ageing
On Clogau two-tone pieces, the gold portions remain bright long after the silver elements have started developing a patina. Over time, this creates a visible contrast between the metals. Some wearers prefer this aged look; others want the silver restored. Both are valid — a polishing cloth on the silver sections addresses it without affecting the gold.
Rose Gold Patina
Clogau rose gold may develop a very gradual deepening of tone over many years. This is caused by the higher copper content in the rose gold alloy. Many wearers consider this a natural patina rather than tarnish — it adds warmth to the piece rather than diminishing it. Rose gold is also more sensitive to chlorine than yellow gold at the same carat weight.
Welsh Gold & Intentional Oxidisation
Clogau's rose gold elements contain a trace of Welsh gold — a defining feature of the brand. Some Clogau designs also use intentional oxidised detailing on the silver elements to create contrast and depth. This darkened finish is a design choice, not tarnish.
Critical: Never Use Silver Dip on Clogau
- Chemical dips strip intentional oxidised detailing permanently
- Silver dip applied to rose gold or gold elements can cause unpredictable discolouration
- Use a polishing cloth on the silver portions only
- For intricate designs (Tree of Life, Celtic Weave), use a soft-bristled brush — or bring it to us for a professional clean
Storage note: Clogau presentation boxes provide reasonable short-term storage but are not designed as long-term anti-tarnish protection. For pieces worn infrequently, transfer to an airtight bag with an anti-tarnish strip. Avoid rubber-lined drawers — rubber contains sulfur compounds that accelerate silver tarnish.

Does BOSS Jewellery Tarnish?
No. BOSS jewellery (manufactured by Movado Group under licence from HUGO BOSS AG) is built on a 316L stainless steel base. This is a low-carbon, marine-grade steel alloy that is chemically resistant to sulfur compounds. It will not discolour, cloud, or develop surface oxidation under any normal wearing conditions. Stainless steel also contains lower nickel levels than many fashion jewellery alloys, reducing skin reaction risk.
Tarnish vs. IP Wear — The Distinction
While the steel base does not tarnish, many BOSS pieces feature Gold Ionic Plating (IP) or Rose Gold IP — a thin coating applied via ionic deposition. This coating does not tarnish either. What it does is wear over time. This is an important distinction:
| Process | What Happens | Cause |
|---|---|---|
| Tarnish | Chemical reaction creates dark surface film | Sulfur compounds in air, moisture, chemicals |
| IP Wear | Physical thinning of plating through friction | Contact with skin, surfaces, clothing, hard impacts |
When IP coating wears through, the silver-tone stainless steel underneath becomes visible. Gold-tone showing silver underneath is not faulty. It is the natural lifecycle of any plated finish.
IP Wear Rates by Piece Type
Rings — Highest Wear
Constant contact with surfaces, taps, steering wheels. IP shows wear first on the inside of the band and at the edges. Rings are the highest-friction jewellery category.
Bracelets — High Wear
Rub against desks, keyboards, and door handles. Clasp backs and link edges wear first. Chain bracelets show less wear than solid bangles.
Necklaces — Moderate Wear
Less friction than wrist-worn pieces. Clasp area sees the most contact. Pendant faces may show wear if they rub against clothing frequently.
Earrings — Lowest Wear
Minimal friction in normal wear. IP coating on earrings can last significantly longer than on rings or bracelets from the same collection.
Caring for BOSS Jewellery
- IP finish: Soft, dry cloth only — no polishing compounds, no silver cloths, no silver dip
- Never use soap on IP pieces — detergents accelerate coating wear
- Never submerge IP pieces in water
- No ultrasonic cleaners on any IP-finished piece — vibration accelerates coating separation
- Bare stainless steel (unplated): Warm water, mild soap, and a soft brush are fine
Leather Care
Some BOSS men's bracelets incorporate leather straps. Leather requires completely different care from metal: use a specialist leather wipe or barely-damp cloth. Never saturate leather. Dry at room temperature, away from direct heat — hairdryers and radiators dry leather too aggressively and can affect adhesive elements in clasps. Leather will dry out, stiffen, and crack if neglected, and this is not recoverable.

Does Vivienne Westwood Jewellery Tarnish?
Yes, and it tarnishes faster than most brands we stock. The reason is the base metal. The majority of the Vivienne Westwood core collection is made from brass (a copper-zinc alloy), electroplated with rhodium, gold, or rose gold. Brass is chosen specifically because it allows the fine casting detail that defines the Orb design — this level of sculptural precision is not achievable at scale in stainless steel or solid silver.
The plating protects the brass, but plating is measured in microns and wears through over time. Once the brass is exposed, tarnish follows.
Plating Lifespan
| Finish | Expected Lifespan (Daily Wear) | Tarnish Appearance When Worn |
|---|---|---|
| Rhodium (silver-tone) | 6–18 months on rings/bracelets; years on earrings | Yellow → brown → dull muted tone |
| Gold plated | Similar to rhodium, varies by friction | Yellow-brown as gold depletes |
| Rose gold plated | Slightly shorter — more reactive alloy | Deeper orange-bronze shift |
| Gunmetal / antique | Longer perceived lifespan | Changes less noticeable (deliberately darker from new) |
Why Brass?
Brass is not a cost-cutting measure. It is a deliberate material choice. The Orb motif requires fine sculptural casting that brass delivers better than harder metals. The trade-off is a base metal that tarnishes when exposed — this is inherent to the material, not a defect in the product.
The Palladium Barrier
On gold-plated Vivienne Westwood pieces, a palladium barrier layer is typically applied between the brass base and the gold plating. Palladium (a platinum-group metal, like rhodium) prevents copper migration from the brass into the gold layer, which would otherwise cause discolouration from within. This is a quality construction detail, but it does not prevent the gold layer itself from wearing through over time.
Hand Sanitiser Warning
Alcohol-based hand sanitiser is highly reactive with plated surfaces. Rings and bracelets are the most vulnerable because they sit directly in the application zone. If you sanitise regularly, remove plated rings and bracelets first, or accept accelerated plating wear. This applies to all plated jewellery, but VW's thinner plating on brass means the effect is more visible sooner.
Re-Plating
When plating wears through on a Vivienne Westwood piece, re-plating (rhodium or gold electroplating) is available through specialist jewellers. This is normal lifecycle maintenance for plated fashion jewellery, not a defect fix. Pieces with Swarovski crystal settings require extra care during re-plating to protect the embellishments.
What Not to Do
- Never use silver dip on plated pieces — it strips rhodium and gold plating from brass irreversibly
- Confirm a piece is sterling silver (not plated brass) before using any chemical cleaner
- Do not soak plated pieces — prolonged water contact accelerates plating degradation
- Avoid sleeping in VW jewellery — hours of friction + body heat + moisture = sustained wear on plating
Sterling silver VW pieces: A smaller part of the range — primarily selected rings and limited-edition pendants. These carry UK hallmarks where the piece exceeds the statutory weight threshold. Sterling silver VW pieces follow standard silver care rules (polishing cloth, anti-tarnish storage).

Does Swarovski Jewellery Tarnish?
The crystals do not tarnish, but the metal settings can. Swarovski jewellery typically uses rhodium-plated base metals for its settings and chains. Rhodium provides a bright, silver-white finish and acts as a protective barrier. Over time — particularly on rings and bracelets worn daily — the rhodium plating wears through, and the base metal underneath may tarnish or discolour.
The crystals themselves are precision-cut glass and are not affected by tarnish. However, they can cloud if exposed repeatedly to perfume, hairspray, or moisture. Wipe crystals with a soft, dry cloth after wearing. Never submerge crystal-set pieces in water, as this can loosen the settings over time.
For care, follow the same rules as any rhodium-plated jewellery: soft dry cloth only, no chemical dips, remove before applying cosmetics, and store in the original Swarovski packaging or an airtight bag when not wearing.

How to Clean Tarnished Silver at Home
These methods apply to sterling silver (925) only. Do not use these on plated jewellery, stainless steel, or pieces with intentional oxidised detailing. When in doubt about what your piece is made from, bring it to us and we will advise.
Method 1: Silver Polishing Cloth (Light Tarnish)
The safest everyday method. Pre-treated cloths contain a gentle polishing compound that removes surface tarnish.
- Rub the tarnished area with straight, back-and-forth strokes (avoid circular motions — they create micro-scratches)
- The cloth turns black — this is the tarnish transferring, which is normal
- Buff with a clean, soft cloth to finish
Method 2: Baking Soda & Aluminium Foil (Heavy Tarnish)
This method uses electrochemistry to reverse tarnishing without removing any silver material. The aluminium acts as a sacrificial metal, transferring sulfur atoms from the silver to the foil.
- Line a bowl with aluminium foil, shiny side up
- Place the tarnished silver on the foil (it must make direct contact)
- Pour in enough boiling water to cover the piece
- Add 1 tablespoon of baking soda per cup of water — it will fizz
- Leave for 2–5 minutes (longer for heavy tarnish)
- Remove with plastic or wooden tongs (not metal), rinse, and pat dry
Why This Works
- Aluminium is more reactive than silver, so it attracts the sulfur away from the Ag₂S layer
- Unlike polishing, this method does not remove any silver — it reverses the chemical reaction
- You may smell hydrogen sulfide (rotten eggs) — this is the sulfur being released
Method 3: Silver Dip (Moderate Tarnish)
Commercial silver dip solutions dissolve tarnish chemically. Effective but aggressive — use with caution.
- Dip the piece for 10 seconds maximum — longer exposure can damage the surface
- Rinse immediately under clean running water
- Pat dry thoroughly with a soft cloth
Do not use silver dip on: gold-plated pieces, rose gold, Clogau two-tone, pieces with intentional oxidised detailing, Vivienne Westwood plated brass, pieces with enamel, or pieces with gemstone settings that may be affected by chemicals.
Method 4: Toothpaste (Emergency Only)
Works as a very mild abrasive, but comes with significant caveats:
- Use plain white, non-gel, non-whitening toothpaste only
- Apply a small amount, rub gently, rinse, and dry
- Toothpaste physically removes a microscopic layer of silver — repeated use thins the surface
- Whitening or gel formulations contain chemicals that can pit or discolour silver
- Not recommended for regular use — a polishing cloth achieves the same result more safely
What NOT to Do
Avoid These Methods
- Lemon juice + salt: Pits the silver surface — the citric acid is too aggressive
- Coca-Cola: Phosphoric acid is unpredictable on different alloys
- Rubber gloves: Contain sulfur — wearing them while cleaning silver makes the tarnish worse
- Vinegar: Works on some alloys, but unpredictable on others — not worth the risk
- Ultrasonic cleaners: Fine for plain solid silver, but damage elastic, loosen stone settings, and strip plating
- Bleach: Reacts aggressively with silver and destroys plating on contact
Cross-Brand Cleaning Notes
| Brand | Key Cleaning Notes |
|---|---|
| ChloBo | Polishing cloth for regular maintenance. Avoid silver dip on gold-plated pieces. Some pieces have oxidised detailing — avoid baking soda on these. No ultrasonic cleaners (elastic and stones). |
| Clogau | Polishing cloth on silver portions only. Never use chemical dips — strips intentional oxidised detailing permanently. Rose gold and Welsh gold elements must not contact silver dip. |
| Nomination | Stainless steel base links do not tarnish. Only 925 silver and gold accents need attention. Avoid submerging enamel links in any solution. |
| Kit Heath | Polishing cloth or baking soda method for plain sterling silver. Avoid dipping pieces with rhodium plating. |
How to Prevent Tarnish
Storage
- Airtight bags: Zip-lock bags or sealed anti-tarnish pouches are the most effective storage method — they limit air exposure to near zero
- Anti-tarnish strips: Small paper strips that absorb sulfur compounds. Place one in each bag or compartment. Replace every 6–12 months.
- No rubber: Rubber bands, rubber-lined drawers, and rubber watch-roll straps release sulfur compounds. Keep rubber away from silver and plated jewellery.
- No bathrooms: The humidity from showers and baths accelerates tarnish faster than almost any other household factor
- Store separately: Prevents scratching between pieces and reduces overall air exposure
- Silica gel packets: A small packet in your jewellery box absorbs moisture and slows tarnishing
Wearing Habits
- Last on, first off: Put jewellery on after perfume, moisturiser, hairspray, and sunscreen have dried completely. Remove jewellery before washing hands, cleaning, or applying hand cream.
- Remove before water: Showering, swimming, washing up, exercising, and any activity involving prolonged moisture
- Wipe after wearing: A quick buff with a soft, dry cloth removes oils and moisture before storage
- Wear regularly: Natural oils from skin create a thin protective layer that slows tarnish. Pieces worn daily often tarnish less than pieces stored for months.

Frequently Asked Questions
Does all jewellery tarnish?
No. Tarnish depends on the metal. Sterling silver (925) tarnishes moderately. Brass tarnishes when exposed. Gold tarnishes extremely slowly (18ct can last decades). Stainless steel (316L) does not tarnish at all. Plated jewellery does not tarnish while the plating is intact, but the base metal may tarnish once the plating wears through.
Does ChloBo tarnish?
Yes. ChloBo is made from 925 sterling silver, which tarnishes naturally when exposed to air, moisture, and sulfur compounds. Tarnish risk is moderate — without care, pieces can develop dullness within weeks. Gold-plated ChloBo tarnishes less because the gold layer acts as a barrier, but it wears over time. Regular wiping and airtight storage prevent most issues.
Does Clogau jewellery tarnish?
The silver elements in Clogau two-tone pieces tarnish at the same rate as any 925 sterling silver. The gold elements (9ct and 18ct) resist tarnish far longer — measured in years, not weeks. Rose gold may develop a gradual deepening of tone over time. On two-tone pieces, the gold stays bright while the silver darkens, creating a contrast shift. A polishing cloth on the silver portions restores the original look.
Does BOSS jewellery tarnish?
No. BOSS jewellery is made from 316L stainless steel, which is chemically resistant to tarnish. Gold and rose gold IP (ionic plating) coatings do not tarnish either — they wear through friction over time, which is a physical process, not a chemical one. If the gold tone wears to reveal the silver steel underneath, this is normal and not a fault.
Does Vivienne Westwood jewellery tarnish?
Yes, and faster than most brands. The base metal is brass, which tarnishes when exposed. Rhodium or gold plating protects the brass, but the plating is measured in microns and wears through with use — typically 6 to 18 months on daily-wear rings and bracelets. Once the brass is exposed, it shifts from yellow to brown to a dull muted tone. Re-plating is available as normal maintenance.
How do you clean heavily tarnished silver at home?
The most effective home method is the baking soda and aluminium foil technique. Line a bowl with foil, place the silver on it, pour boiling water over it, and add one tablespoon of baking soda per cup of water. Leave for 2 to 5 minutes. The aluminium acts as a sacrificial metal, transferring sulfur from the silver to the foil without removing any silver material. Rinse and dry thoroughly afterwards.
Does wearing silver stop it from tarnishing?
It slows tarnishing significantly. Natural oils from your skin create a thin protective layer on the silver surface. Pieces worn daily often develop less tarnish than pieces stored for months. However, wearing does not stop tarnish completely — exposure to perfume, hand cream, and moisture while wearing can still cause darkening.
Can you prevent tarnish completely?
Not entirely, but you can slow it to the point where it is barely noticeable. Airtight storage with anti-tarnish strips, wiping after every wear, and following the “last on, first off” rule cover the vast majority of prevention. The only metals that truly resist tarnish indefinitely are high-carat gold (18ct+) and stainless steel.
