Walk into any jewellery store in India and you will see gleaming white gold rings, earrings, and pendants that appear almost indistinguishable from platinum. That striking white brilliance is not the natural colour of white gold — it is the work of rhodium plating. Understanding rhodium, how it is applied, how long it lasts, and what re-plating costs in India will help you make informed decisions about your white gold jewellery.
What Is White Gold, Really?
White gold is not a naturally occurring metal. It is an alloy created by combining pure yellow gold with white metals to reduce the characteristic yellow colour. Common white metal additions include:
- Palladium — the premium choice for modern white gold; naturally white, hypoallergenic, produces a near-white alloy
- Nickel — traditional and cheaper, but a known allergen; causes contact dermatitis in 8–12% of the population; increasingly avoided in quality jewellery
- Silver — sometimes added in combination with palladium or nickel; produces a grey-ish white alloy
- Zinc and copper — sometimes included for workability, though these push the alloy colour toward yellow or grey
The result is an alloy that is naturally greyish-yellow or yellowish-white — not the bright crisp white that most buyers expect. This is why virtually all white gold jewellery sold in India and globally receives rhodium plating before sale.
What Is Rhodium?
Rhodium is a rare platinum-group metal — one of the rarest and most valuable metals on Earth. Its properties make it exceptional for jewellery surface treatment:
| Property | Value / Detail | Why It Matters for Jewellery |
|---|---|---|
| Colour | Brilliant white, highly reflective | Gives white gold its crisp white appearance |
| Hardness (Mohs) | 6.0–6.5 | Harder than gold (2.5–3.0) — scratch resistant surface |
| Corrosion resistance | Excellent — does not tarnish or oxidise | Protects the underlying gold alloy |
| Reflectivity | 78% (vs platinum 72%) | Gives diamonds maximum brilliance against the metal |
| Hypoallergenic | Yes — inert at body temperature | Shields skin from nickel in white gold alloy |
| Plating thickness | 0.1–1.0 microns typically | Extremely thin — will wear through over time |
The Rhodium Plating Process
Rhodium plating is an electroplating process. The jewellery piece is cleaned thoroughly, sometimes polished to remove surface scratches, then suspended in a rhodium solution. An electric current is passed through the solution, causing dissolved rhodium ions to deposit uniformly onto the gold surface. The entire process for a standard ring takes about 30–60 minutes at a jewellery workshop.
Plating thickness varies by jeweller and application. Thicker plating (closer to 1.0 micron) lasts significantly longer than the minimal 0.1-micron flash plating sometimes used on lower-price pieces. Asking your jeweller for "heavy rhodium plating" when having the service done is worth the slightly higher cost.
How Long Does Rhodium Plating Last?
This is the most-asked question about white gold in India, and the honest answer is: it depends. Typical range is 1–3 years for regular-wear pieces, but multiple factors affect this significantly:
| Factor | Impact on Plating Life |
|---|---|
| Wear frequency | Daily wear: 1–1.5 years. Occasional wear: 3–5 years. |
| Skin pH (acidity) | Acidic skin chemistry (low pH) wears rhodium significantly faster. Sweaty skin accelerates wear. |
| Contact with chemicals | Chlorine, perfume, hand sanitiser, household cleaners all accelerate wear. |
| Piece type | Rings (high abrasion from surfaces) wear fastest. Earrings and pendants last much longer. |
| Plating thickness | Thicker plating (0.5–1.0 micron) lasts roughly 2–3x longer than thin flash plating. |
| Indian climate | Heat and humidity accelerate wear compared to temperate climates. |
Signs Your Rhodium Plating Is Wearing Off
The most visible sign is a yellowish tinge appearing in high-contact areas — typically the back of a ring shank where it presses against adjacent fingers, the underside of a clasp, or the edges of a pendant bail. This yellow appears because the underlying white gold alloy's natural colour (yellowish-grey) is becoming exposed.
Other signs include: reduced brightness and reflectivity, a slightly warm (yellowish) cast to the whole piece rather than crisp white, and in nickel white gold, possible skin reactions beginning at wear points.
💡 Pro Tip
Do not wait until the yellow is obvious before re-plating. Once the alloy is visible, it means the protection layer is very thin or gone in that area. Re-plating when you first notice the yellowing is cheaper and produces better results than waiting until the piece looks significantly discoloured.
Re-Plating Cost in India (2025)
Rhodium re-plating is widely available across Indian cities at jewellery workshops and through larger chain jewellers. Approximate cost guide:
- Simple ring — ₹500–₹1,200
- Ring with stone settings — ₹800–₹2,000
- Necklace or chain — ₹1,000–₹2,500 depending on length and complexity
- Earring pair (simple) — ₹400–₹900
- Bracelet — ₹700–₹2,000
- Pendant — ₹400–₹1,000
Where to get re-plating done: Tanishq and Malabar Gold offer rhodium re-plating for pieces purchased from them. Most standalone goldsmithing workshops (kaarigar) with electroplating equipment will re-plate any piece. Ask specifically whether they offer thick or standard plating and whether the price includes pre-polishing.
White Gold vs Platinum — The Ongoing Confusion
Rhodium-plated white gold and platinum look visually identical to the untrained eye. Both are brilliant white and highly reflective. The practical differences are significant:
- Cost: Platinum jewellery costs 3–5 times more than equivalent white gold for the same design, due to platinum's higher density, rarity, and more difficult manufacturing process
- Maintenance: White gold requires periodic re-plating; platinum maintains its white colour permanently (though it develops a patina from micro-scratches over time)
- Weight: Platinum is significantly heavier (density 21.45 g/cm³ vs gold 19.3 g/cm³) — a platinum ring feels noticeably heavier than an identical white gold ring
- Hallmarking: Platinum jewellery in India is hallmarked "PT950" or "PT900"; white gold is hallmarked "18K" or "750" — check the stamp to know what you have
Palladium White Gold — The Modern Alternative
Palladium white gold — where the primary white metal additive is palladium rather than nickel — has grown in popularity in India. Palladium white gold alloys are naturally whiter than nickel white gold, reducing the yellow tinge. This means the rhodium plating can be thinner and still maintain good colour, and the underlying colour when plating wears is less jarringly yellow. Palladium white gold is also completely nickel-free, eliminating allergy concerns. The trade-off is a higher initial cost.
⚠️ Nickel Allergy Warning
If you or a family member experiences skin irritation, redness, or itching when wearing white gold jewellery, the cause is almost certainly nickel in the alloy becoming exposed as the rhodium plating wears thin. Seek nickel-free white gold (palladium white gold) or have the piece immediately re-plated. Continued wear of thin-plated nickel white gold on sensitised skin can worsen the allergy response over time.
Care to Extend Rhodium Plating Life
You cannot prevent rhodium plating from eventually wearing off, but you can significantly extend its life:
- Remove white gold jewellery before swimming, bathing, or using any water (chlorine and mineral water both accelerate wear)
- Apply perfume and cosmetics before putting on jewellery — never spray perfume directly on or near white gold
- Avoid hand sanitiser contact with white gold rings when possible
- Remove before household cleaning, gardening, or gym exercise
- Store white gold pieces separately to prevent metal-on-metal abrasion
- Clean only with warm water and very mild soap — no ultrasonic cleaners for rhodium-plated pieces if you want to maximise plating life
Frequently Asked Questions
Does rhodium plating make white gold look exactly like platinum?
Fresh rhodium plating is visually identical to platinum — both are bright white and highly reflective. After plating wears in high-contact areas, white gold begins to show its natural yellowish tinge, which does not happen with platinum. The weight difference (platinum is denser) is the most reliable tactile differentiator.
Can I plate rose gold or yellow gold with rhodium to make it white?
Technically yes, any metal can be rhodium plated. However, on yellow gold or rose gold the rhodium layer will wear off much faster because the underlying metal colour contrast is greater — revealing yellow or pink as soon as the plating thins. The result also looks artificial and requires very frequent re-plating. This is not a recommended or common practice.
Is rhodium plating safe? Will it cause skin problems?
Rhodium itself is hypoallergenic and completely safe against skin contact. In fact, the rhodium layer protects sensitive skin from the nickel in white gold alloy underneath. Skin reactions to white gold jewellery indicate the rhodium plating has worn thin and the nickel alloy is now in contact with skin — the solution is immediate re-plating, not discontinuing wear.
My white gold engagement ring was bought 4 years ago and still looks white. Does it need re-plating?
If it still looks uniformly white and bright with no yellowing at the edges or wear points, the plating may still be adequate. Inspect under bright light especially on the back of the shank. If you see any yellow tinge, schedule re-plating. If it looks fine, a once-a-year professional inspection is sufficient.
How do I know if my white gold is nickel-based or palladium-based?
Ask your jeweller directly — they should be able to tell you the alloy composition. Some hallmarked pieces specify the alloy on the certificate. If you experience skin reactions at wear points where the rhodium has thinned, suspect nickel white gold and switch to palladium white gold or platinum for future purchases. Nickel-free white gold is increasingly available and is the responsible choice for jewellers serving customers with sensitive skin.
Rose Gold and Yellow Gold — No Rhodium Needed
It is worth clarifying that rhodium plating is a white-gold-specific maintenance requirement. Yellow gold and rose gold jewellery do not receive rhodium plating and do not need it. Yellow gold maintains its colour from the gold-copper-silver alloy composition itself. Rose gold gets its characteristic pink-blush tone from a higher copper content in the alloy — typically 75% gold + 22.5% copper + 2.5% silver for 18K rose gold. Neither requires any surface coating, and neither will develop the "yellowing" phenomenon that white gold experiences when rhodium wears off.
