Gold vs Platinum

Gold and platinum are the two metals almost every fine ring is made from, and the comparison is more interesting than most guides make it.

The short version: gold gives you colour and costs less, platinum gives you permanence and holds stones better. Neither is objectively superior. What follows is how they actually differ, including the parts that get repeated incorrectly almost everywhere.

We work both metals daily at our Mt Hawthorn studio, and there is a certain irony in explaining gold to people in a state that has been digging it out of the ground at Kalgoorlie since 1893.

How Each Metal Is Measured

The two metals use completely different purity systems, which is where most confusion starts.

Gold is measured in carats out of 24. Pure gold is 24 carat and far too soft for a ring worn daily, so it is alloyed with other metals for strength. In Australia you will mostly see 18 carat, which is 750 parts pure per thousand, and 9 carat, which is 375 parts. Higher carat means richer colour and a softer metal. Lower carat means harder and cheaper.

Platinum is measured in parts per thousand and is used at far higher purity. Most jewellery platinum is 950, meaning 95 per cent pure. So a platinum ring contains substantially more precious metal than even an 18 carat gold one.

Durability: Which Actually Lasts Longer

This is the point almost every article gets wrong, so it is worth being precise.

Platinum is not harder than 18 carat gold. In surface hardness terms it is comparable and in some alloys slightly softer, which means platinum shows fine scratches readily and develops a soft satin patina over years of wear. Plenty of people prefer that look. Some do not, and it can be polished back.

What platinum does differently is far more important. When gold is scratched, a small amount of metal is removed and lost. When platinum is scratched, the metal displaces rather than disappearing. It moves aside and forms a microscopic burr instead of shedding.

Across thirty years that difference compounds, and you see it most clearly in claws. A platinum claw retains far more of its original mass than a gold one, which is why platinum holds stones more securely over a lifetime and why we frequently build a yellow gold ring with platinum claws. It is also why gold rings come back to the bench for retipping more often than platinum ones do. Our settings guide covers what that means for each design.

Colour And Appearance

Gold wins on choice, comfortably.

• Yellow gold is the natural colour of the metal, warmed or muted depending on carat. It needs nothing but occasional polishing.
• Rose gold takes its colour from copper in the alloy, which also makes it marginally harder than yellow or white.
• White gold is yellow gold alloyed pale and then rhodium plated to make it properly white. That plating is microns thick and wears through, so expect to re-plate every twelve to twenty four months. Nobody tells people this at the point of sale and it is a genuine ongoing cost.
• Platinum is naturally white and stays white for life. It never needs plating, and it will not tarnish. If you want a white metal and dislike maintenance, that single fact usually decides it.

Comfort, Weight And Skin

Platinum is dense. Around 21 grams per cubic centimetre against roughly 15 for 18 carat gold, which means the identical ring made in platinum weighs about 40 per cent more.

Some people love that. A platinum band feels substantial in a way gold does not, and plenty of clients describe it as feeling more like an object and less like a decoration. Others find it heavy, particularly in a wide band. It is entirely personal and it is worth handling both before deciding.

On skin, platinum at 950 is naturally hypoallergenic and about as inert as jewellery metal gets. White gold has historically been alloyed with nickel, which is the most common contact allergen in jewellery. Most quality Australian white gold now uses palladium instead, but if you have reacted to jewellery before, ask what the alloy contains rather than assuming.

Price And What Drives It

Platinum rings cost more than gold ones, and the reason is not the one most people assume.

Three things stack up. Platinum is usually priced higher per gram than gold, though not always, which we will come back to. A platinum ring needs roughly 40 per cent more metal by weight for the same design because of the density. And platinum is genuinely harder to work, requiring higher temperatures, separate tools and separate benches to avoid contamination, so the labour is greater. That last part is a real cost rather than a margin.

Now the nuance almost nobody includes. Gold behaves as a safe-haven asset with relatively steady long-term price behaviour. Platinum is driven heavily by industrial demand, principally autocatalysts, so its price is far more volatile, and there have been extended periods where platinum traded below gold. The claim that platinum is always the more expensive metal is not reliable. Ask what it costs on the day.

For what the metal contributes to a whole ring, our guide to what an engagement ring costs puts it in context.

Which Metal Suits Which Ring

Working backwards from the brief rather than the metal.

• Choose platinum if you want a white metal with no maintenance, if the ring will be worn hard, if you have sensitive skin, or if you want the most secure possible hold on a valuable centre stone.
• Choose yellow or rose gold if you want warmth and colour, if a lower colour grade in the stone would suit you better, or if the budget is better spent on the diamond than the metal. Warm metals also forgive a slightly warmer diamond, which can free up real money. Our diamond clarity guide explains how those grades interact.
• Choose white gold if you want the platinum look at a lower price and you will genuinely keep up with re-plating.
• Mix them, which is increasingly what people do. A yellow gold band with platinum claws gets you warmth and security at once, and it is one of the more common briefs we build.

Frequently Asked Questions

The five we field most often about metals.

Is Platinum Better Than Gold?

Not better, different. Platinum is more secure over decades and needs no maintenance. Gold offers colour, costs less and is easier to work. The right answer depends on the ring and the hand.

Does Platinum Scratch More Than Gold?

It shows scratches more readily and develops a satin patina, but it loses almost no metal in the process. Gold scratches less visibly and sheds material as it does, which matters far more over thirty years.

Is White Gold Or Platinum Better?

Platinum if you want white and hate maintenance. White gold if you want the look for less and will re-plate every year or two. They are visually near identical when the white gold is freshly plated.

Is Platinum Always More Expensive?

No. Platinum usually costs more, both per gram and because a ring needs more of it, but its price is driven by industrial demand and has at times fallen below gold. Ask on the day.

Which Metal Is Best For Sensitive Skin?

Platinum at 950, which is close to inert. If you prefer gold, ask for a nickel-free alloy and consider 18 carat over 9 carat, since higher purity means less alloy against the skin.

Come And Handle Both

The weight difference is the thing you cannot get from an article, and it decides this question for a lot of people.

Come to our Mt Hawthorn studio and hold the same band in 18 carat gold and in platinum. Feel the difference across a knuckle, look at a worn platinum ring next to a worn gold one, and see what thirty years of patina actually looks like rather than what it sounds like. We will also quote the metal honestly on the day, since platinum pricing moves.

The bench behind the counter carries close to two centuries of combined experience, and every commission moves from 3D rendering to a silver prototype you can wear before anything is cast in either metal.
