Rhodium Plated vs Gold Plated Jewellery: Which Lasts Longer?

You are looking at two similar brass earrings. One is labelled "gold plated" and the other "18K rhodium gold plated." The price difference is small, but you are not sure which one to choose or what the difference actually means for a piece you plan to wear regularly. This is one of the most common questions we get at Kansya, and it matters: the plating on a jewellery piece determines how long it looks new, how it behaves on sensitive skin, and how you should care for it. Here is the full picture.

What is gold plating?

Gold plating is a process in which a thin layer of gold (or gold alloy) is deposited onto a base metal (usually brass or copper) through electroplating. The base metal provides structure and affordability; the gold layer provides colour and a degree of tarnish resistance. The thickness of the gold layer is measured in microns, and "18K gold plated" refers to the purity of the gold used in the plating layer (18 out of 24 parts gold, or 75% gold), not the thickness.

Gold is a relatively soft metal. This means gold-plated surfaces can show scratches, wear patterns, and fading with regular use. How quickly this happens depends on the thickness of the plating layer, how often the piece is worn, and what it is exposed to (water, perfume, friction against clothing or skin).

What is rhodium plating?

Rhodium is a platinum-group metal: rarer than gold, harder, and naturally bright white in colour. Rhodium plating is applied to a base metal (or over a gold-plated layer) in an extremely thin layer, typically 0.1 to 1 micron. Because rhodium is so much harder than gold, even a very thin rhodium layer adds significant scratch resistance to the surface beneath it.

Rhodium does not tarnish in ordinary conditions, does not react with most acids or chemicals, and contains no nickel, which is the primary cause of metal allergies. These properties make it one of the most practical plating choices for everyday jewellery: a piece stays bright longer, requires less maintenance, and is safer for most skin types.

How do rhodium and gold plating compare on durability?

Rhodium wins on durability. Gold has a Mohs hardness rating of approximately 2.5 to 3, making it soft enough to scratch with a fingernail. Rhodium sits at around 6, similar to feldspar, which means it resists everyday abrasion significantly better. A gold-plated piece worn daily might begin to show wear at friction points (the back of a ring, the posts of earrings, the clasp of a bracelet) within a few months. A rhodium-plated piece typically shows comparable wear after a year or more of regular use.

That said, no plating lasts indefinitely. All plated jewellery will eventually show wear at high-contact points. The practical difference is how long it takes to get there and how uniform the finish stays in the meantime.

Which is better for sensitive skin?

Rhodium is significantly better for sensitive skin. The most common cause of jewellery allergies is nickel, which is often present in lower-quality brass alloys and gold-plated finishes as a hardening agent. Rhodium contains no nickel and is chemically inert against skin, meaning it does not react with sweat, acids, or body chemistry the way lower-grade metals can.

If you have had reactions to gold-plated jewellery in the past, the reaction was almost certainly caused by the base metal or alloy beneath the plating (once the plating wears thin) rather than the gold itself. Rhodium-plated pieces maintained in good condition are unlikely to cause the same reaction because the rhodium layer remains as a barrier for longer.

What is 18K rhodium gold plating, and why does Kansya use it?

18K rhodium gold plating describes a finishing process in which a brass base is first plated with 18-karat gold (75% gold alloy) and then given a rhodium top coat. The gold layer provides the warm colour; the rhodium layer on top provides the hardness and scratch resistance. The result is a finish that looks like gold but wears more like rhodium.

This is the finish used on every piece in the Kansya collection, from the Drop Down Cement Earrings to the Evil Eye Ring With Pearl to the Hamsa Evil Eye Bracelet. We chose it because the combination resolves the main trade-off between the two plating types: you get the warmth and familiarity of gold tone with the durability and skin safety of a rhodium surface.

How should you care for rhodium gold-plated jewellery?

The care principles are the same regardless of plating type, but they matter more for gold-plated pieces than for rhodium-plated ones because gold wears faster.

Keep pieces away from water, perfume, hairspray, and skincare products. Put jewellery on last, after getting ready. Remove pieces before bathing, swimming, or washing hands. Wipe gently with a soft dry cloth after each wear to remove sweat and oils. Store in separate airtight pouches to prevent pieces scratching each other. For more detail on daily jewellery habits, our piece on brass earrings for everyday style covers the same principles applied to a broader range of pieces.

Frequently Asked Questions

Does rhodium plating turn your skin green?

No. Skin turning green is caused by copper in the base metal reacting with skin acids, usually visible when plating wears thin and the base metal is exposed. Rhodium itself does not react this way. As long as the rhodium layer on a piece is intact, you will not see skin discolouration. Maintaining the plating through proper care is the best prevention.

How long does 18K rhodium gold plating last?

With regular care (no water exposure, no chemicals, stored properly), 18K rhodium gold-plated jewellery typically maintains its finish for one to two years of everyday wear, and considerably longer with occasional wear. The areas that wear fastest are high-friction points: the inside of rings, the posts of earrings, and clasp mechanisms on bracelets.

Can rhodium-plated jewellery be re-plated?

Yes. A local jeweller can re-plate a brass-base piece with rhodium or gold for a relatively low cost. This effectively restores the finish and gives the piece another full lifespan. If you have a piece you particularly like, re-plating when the finish starts to wear is a practical and sustainable choice compared to replacing it.

Is rhodium plating more expensive than gold plating?

As a raw material, rhodium is rarer and more expensive than gold per gram, but because plating layers are extremely thin (fractions of a micron), the additional material cost per piece is small. The price difference between a rhodium-plated and a standard gold-plated piece at retail is typically modest. Over time, the longer lifespan of rhodium-plated pieces often makes them more cost-effective.

Is brass a good base metal for plated jewellery?

Yes. Brass (an alloy of copper and zinc) is one of the most commonly used base metals for fashion and handcrafted jewellery. It is strong enough to hold detailed shapes, workable enough for hand-forming and casting, and inexpensive enough to keep the final price accessible. The brass itself has no direct contact with skin when the plating is intact. For the full picture on brass jewellery, see our brass earrings everyday style guide.

Can I shower with rhodium gold-plated jewellery?

It is best not to. Even though rhodium itself is water-resistant, repeated exposure to hot water, soap, and steam accelerates wear on the plating and on the brass base beneath it. The gold layer between the brass and the rhodium coat is particularly susceptible to soap and hot water. Remove plated jewellery before showering to preserve the finish significantly longer.

Conclusion

For everyday handcrafted jewellery, 18K rhodium gold plating is the more practical choice: harder, longer-lasting, safer for sensitive skin, and requiring the same simple care as standard gold-plated pieces. It is why every piece in the Kansya collection uses this finish. If you are building a collection of pieces you plan to wear regularly rather than occasionally, the plating underneath your jewellery is worth understanding. Browse the full Kansya collection to find pieces finished to this standard across every category.
