Silver vs White Gold vs Platinum: What’s the Difference?
Silver vs White Gold vs Platinum: What’s the Difference?
Silver, white gold and platinum can look surprisingly similar when freshly polished, but they are very different metals to wear.
Their weight is different. Their maintenance is different. They age differently, and some are far better suited to engagement rings and stone-set jewellery than others.
When choosing a white metal, we look beyond colour alone. How often will the piece be worn? Does it need to securely hold a valuable gemstone? Do you mind occasional maintenance? Do you prefer a lightweight ring or something with a little more weight on the hand?
In our Adelaide studio, we work with different precious metals depending on the piece being made. For an engagement ring intended to be worn every day, our recommendations can be very different to those for a simple dress ring, pendant or occasional piece.
Understanding how each metal behaves makes choosing between silver, white gold and platinum much easier.
Silver, white gold and platinum purity
Although all three can appear white, their composition is completely different.
Silver, with 7.5% alloy added for strength.
Pure gold, with 25% alloying metals.
Pure platinum, with only 5% alloy.
This high platinum content is one of the reasons platinum feels so different when you hold it. It is an exceptionally dense metal and has noticeably more weight than either silver or white gold.
Sterling silver
Silver is a beautiful precious metal and an excellent option for many types of jewellery.
It gives you a naturally bright white appearance at a much more accessible price point than gold or platinum, which makes it particularly well suited to dress jewellery, pendants, earrings, larger statement pieces and simple bands.
Most jewellery described simply as “silver” is actually sterling silver. Pure silver is extremely soft, so sterling silver combines 92.5% silver with 7.5% harder alloying metals to improve its strength.
Even as sterling silver, however, it is still a relatively soft jewellery metal.
For this reason, we generally would not recommend silver for an engagement ring carrying a valuable centre stone, particularly when the design relies on fine claws. Over years of daily wear, silver is more susceptible to bending, distortion and surface wear than white gold or platinum.
Fine claws are especially important. They are responsible for physically securing your gemstone, so we prefer a metal better suited to maintaining those small structural details over long-term daily wear.
That does not make silver a poor-quality metal. It simply means it is better suited to certain pieces than others.
A solid silver band, sculptural dress ring or jewellery piece that is not expected to carry an important gemstone can be a beautiful and budget-friendly choice.
Does silver tarnish?
Yes. Sterling silver reacts with sulphur compounds in the environment, causing its surface to darken over time. Moisture, perspiration, chemicals and environmental conditions can all accelerate tarnishing.
Fortunately, tarnish is generally a surface change rather than permanent damage and can usually be removed through polishing.
Some people enjoy the slightly darker patina that develops on silver jewellery. Others prefer to keep it bright and regularly polished.
Either way, it is worth knowing that silver will require more ongoing cleaning if you want to maintain a consistently bright white finish.
What is white gold?
White gold begins with gold, which is naturally yellow.
To create white gold, pure gold is combined with white-coloured alloying metals. In 18ct white gold, 75% of the finished alloy remains pure gold, while the remaining 25% is made up of other metals.
Not all white gold alloys are the same.
Some lower-cost white gold alloys use nickel and can retain a slightly warmer or more yellow-toned appearance beneath the rhodium plating.
At Carmen & Lucy Fine Jewellery, we use a palladium-based white gold alloy with no nickel.
Palladium gives our white gold a naturally cool, steely colour. Without rhodium plating, it has more of a soft gunmetal or spacey-grey appearance rather than the warmer yellowish-white tone sometimes associated with other white gold alloys.
Does our white gold need rhodium plating?
Technically, no.
Because we use a palladium-based white gold alloy, the metal is already naturally cool in colour and can be worn without rhodium plating.
Unplated, our white gold has a softer grey tone that can look slightly industrial. Some clients really like this finish, particularly when they prefer something less bright.
For a more traditional, crisp white appearance, we rhodium plate the finished piece.
Rhodium is an exceptionally white metal from the platinum group. A very thin layer is applied over the white gold, creating the bright, reflective finish most people associate with white gold jewellery.
The important thing to understand is that rhodium plating is a surface finish. It does not last forever.
Over time, friction gradually wears through the rhodium, particularly on the underside of a ring and anywhere that regularly rubs against the skin or another ring.
When this happens, the cooler grey colour of our palladium white gold will begin to show underneath.
The ring can simply be rhodium plated again, or some clients choose to leave the white gold unplated and allow its natural colour to become part of the look.
Rhodium-plated vs unplated white gold
The difference is primarily visual.
Neither is inherently better. It comes down to the look you prefer and whether you want to maintain the brighter rhodium finish over time.
For clients who like a more conventional bright-white engagement ring, rhodium plating is generally the preferred finish.
For clients who are drawn to something slightly moodier or more contemporary, unplated palladium white gold can be incredibly beautiful.
How does white gold wear?
For engagement rings and everyday fine jewellery, white gold is a very practical option.
It can hold fine setting details well, works beautifully with diamonds and coloured gemstones, and has less physical weight than platinum.
Like all precious metals, it will scratch with wear.
If the ring is rhodium plated, that surface finish will also gradually wear away. This does not mean the metal underneath is damaged. It simply means the natural cool-grey colour of the palladium white gold begins to show through.
If you prefer the ring to remain bright white, it can be rhodium plated again as required.
For clients who want a lighter ring than platinum, excellent setting strength and a crisp polished appearance, white gold remains an excellent choice.

What is platinum?
Platinum is a completely different metal from white gold.
Rather than beginning with yellow gold and changing its colour through alloying, platinum is naturally white.
Jewellery stamped Pt950 is typically 95% platinum, making it considerably purer than 18ct gold.
Platinum does not require rhodium plating to remain white, and it does not tarnish in the way silver does.
Its natural colour is slightly softer and greyer than freshly rhodium-plated white gold.
This is an important distinction: platinum is naturally white throughout the metal, while rhodium-plated white gold can actually appear brighter and more reflective when freshly finished.
For clients who want a naturally white metal without ongoing rhodium maintenance, platinum has a clear advantage.
Platinum is much denser
One of the easiest differences to notice between platinum and white gold is simply picking the rings up. Platinum is a much denser metal, so the same ring will feel noticeably heavier when made in platinum.
As a simple example, a ring that weighs around 5g in 18ct white gold would weigh approximately 6.5g in platinum when made to the same dimensions.
How does platinum wear?
Platinum has a very distinctive way of ageing.
It will scratch. In fact, clients are sometimes surprised by how quickly a highly polished platinum ring begins to show fine marks.
But platinum wear is different to simply losing metal.
Rather than significant amounts of material being worn away, much of the platinum is displaced across the surface. Over time, these tiny marks build into the soft, slightly frosted finish known as platinum patina, giving your ring a worn-in, vintage appearance more quickly.
Some people love the patina and allow it to develop naturally.
If you prefer the ring highly polished, platinum can be professionally refinished.
Is platinum hypoallergenic?
Platinum is generally an excellent option for people with sensitive skin.
Pt950 jewellery contains approximately 95% platinum and is widely regarded as hypoallergenic because of its high purity.
Our palladium-based 18ct white gold is also nickel-free, making it a good option for clients who want white gold but wish to avoid nickel-based alloys.
For anyone with a known metal allergy or sensitivity, we still recommend discussing this with us before the piece is made so we can choose the most suitable alloy.
Silver vs white gold vs platinum for engagement rings
For an engagement ring intended to be worn every day, our preference is generally white gold or platinum rather than sterling silver.
Silver can make a beautiful ring, but its relative softness makes it less suitable for the fine claws and delicate structural elements often required to securely hold an important diamond or gemstone over many years.
White gold gives you excellent stone-setting properties and a lighter feel on the hand. Our palladium-based white gold is naturally cool and grey in colour and can be worn unplated, or rhodium plated for a brighter white finish.
Platinum is naturally white, considerably denser and extremely well suited to long-term stone setting. It does not require rhodium plating and retains its metal very well over time.
For particularly valuable stones, delicate settings or clients who want to avoid rhodium maintenance entirely, platinum is often our preference.
For clients who prefer a lighter ring or love the crisp appearance of rhodium-plated white gold, 18ct palladium white gold is an excellent alternative.
What about wedding rings?
All three metals can work for a wedding band, depending on the design and how it will be worn.
A plain sterling silver wedding band can be a beautifully simple and accessible option, particularly when budget is a priority. It will scratch, wear down and tarnish over time, but many people enjoy the character this creates.
You may need to purchase a second wedding ring later in life, though, as silver wears down relatively quickly and can become significantly thinner over time compared with white gold and platinum.
For a wedding band worn directly beside an engagement ring, we generally prefer to match the metals where possible.
Which white metal should you choose?
There is no universally “best” white metal. The right choice depends on the jewellery you are making.
The differences are much easier to understand when you can physically compare them.
In our Adelaide studio, we can show you different metals and finishes side by side and talk through the design, lifestyle and maintenance considerations before deciding what is right for your piece.

Silver vs White Gold vs Platinum FAQ
Is platinum better than white gold for an engagement ring?
Both are excellent engagement ring metals. Platinum is naturally white, denser and does not require rhodium plating, while white gold is lighter and can achieve a brighter white finish when rhodium plated. The better choice depends on your design and maintenance preferences.
Does white gold always need rhodium plating?
No. Our 18ct white gold uses a palladium-based, nickel-free alloy and can be worn without rhodium plating. Unplated, it has a cool grey or gunmetal appearance. Rhodium plating is used when a brighter, crisper white finish is preferred.
What colour is unplated white gold?
This depends on the alloy. Our palladium-based white gold has a cool, spacey-grey appearance when left unplated rather than a strong yellow undertone. Rhodium plating changes the surface to a much brighter, more reflective white.
How often does white gold need rhodium plating?
There is no single schedule, but generally every six months to one year. It depends on how often the jewellery is worn, the amount of friction it receives and how bright you prefer the finish to remain.
Does platinum scratch?
Yes. Platinum scratches and develops a natural patina with wear. However, it is highly wear resistant and tends to retain its metal exceptionally well over time.
Does sterling silver tarnish?
Yes. Sterling silver naturally tarnishes through exposure to sulphur compounds, moisture and other environmental factors. The tarnish can usually be removed through appropriate cleaning and polishing.
Is silver suitable for an engagement ring?
We generally do not recommend sterling silver for a valuable stone-set engagement ring intended for constant daily wear. It is softer than white gold and platinum, making fine claws and other delicate structural areas more susceptible to bending and wear. Silver can, however, be an excellent option for plain bands, dress rings and more budget-friendly jewellery.
Is platinum hypoallergenic?
Pt950 platinum is generally considered hypoallergenic and is one of the metals we would consider first for someone with sensitive skin. Our palladium-based white gold is also nickel-free, which makes it a suitable alternative for many clients wishing to avoid nickel-containing white gold alloys.
Is platinum heavier than white gold?
Yes. As a general example, a ring weighing around 5g in 18ct white gold would weigh approximately 6.5g in platinum if made to the same dimensions.
Which metal stays white the longest?
Platinum is naturally white throughout the metal and does not require plating to maintain its colour. Our palladium white gold is also naturally cool in colour, but has more of a grey appearance when unplated. Rhodium plating creates the much brighter white surface commonly associated with white gold jewellery. Sterling silver is naturally silver-white but will tarnish and require cleaning.
