Platinum and gold are the two metals fine jewellery is built on, and when it comes to a white metal in particular, platinum and white gold are the choice most people weigh up. This guide compares them on colour, durability, how securely each holds a gemstone, price and skin-friendliness, so you can choose with the full picture.
Platinum is naturally white, denser and more hard-wearing than gold, it holds gemstones especially securely, and it never needs replating, but it costs more. Gold comes in yellow, white and rose, is lighter and more affordable, and white gold needs occasional rhodium replating to stay bright white. For a white metal, platinum is the low-maintenance, secure premium choice, and white gold is the near-identical option for less.
What is the difference between platinum and gold?
The core difference is that platinum is a naturally white precious metal used in a very pure form, usually around 95 percent platinum, while gold is naturally yellow and is always mixed with other metals to make it hard enough to wear, which is what gives gold its different karats and its yellow, white and rose colours. Platinum is also noticeably denser, so a platinum piece feels heavier and more substantial in the hand than the same piece in gold. Both are precious, long-lasting metals, they simply behave differently.
Colour and upkeep
Platinum is white all the way through and stays that way for life, so it never needs any surface treatment to hold its colour. White gold is different: it is finished with a thin layer of rhodium to look bright white, and that finish gently wears and is refreshed by occasional replating, as our guide to white gold and rhodium plating explains. So the two can look almost identical on the day, but platinum keeps its colour with no upkeep, while white gold asks for a light touch of maintenance to stay at its brightest.
Durability, metal memory and holding a stone
Platinum is prized for how it wears and how it holds a stone, and the reason comes down to a property jewellers call memory. Memory is how strongly a metal springs back toward its original shape after it is bent. Platinum has low memory: it is malleable, so when it is worked or knocked it tends to move and stay where it is put rather than springing back or cracking. Gold has more memory and is more brittle by comparison, so it is more inclined to spring back, and its prongs are a little more likely to crack or wear thin over many years.
This matters most where metal grips a gemstone. A platinum claw bends around a stone and holds it, and if it is knocked it deforms rather than snapping, which is why platinum is so often chosen to secure valuable stones. Platinum also wears differently: instead of gradually losing metal the way gold does, it mostly displaces, so a scratch pushes metal aside rather than removing it, and a jeweller can polish or burnish it back. Over decades this means platinum settings tend to hold up with less loss of metal. As one example, that secure grip lets a delicate setting rely on the claws alone, even without a gallery rail, the small support bar that runs under a stone to brace the claws, which a gold setting might need for the same security. Platinum also work-hardens, meaning it actually strengthens as a jeweller works it.
Price
Platinum costs more than gold for a comparable piece, often around 40 to 50 percent more than the same design in white gold. Two things drive this: platinum is used in a purer form, and it is denser, so a piece takes more metal by weight to make. You are paying for that extra purity and mass, and for a metal that needs no replating over its life.
Which is kinder to skin?
Both suit most people, but platinum has a slight edge for sensitive skin. Because it is used in such a pure form and contains no nickel, platinum is naturally hypoallergenic and very unlikely to cause a reaction. White gold depends on its alloy: a nickel-based white gold can irritate sensitive skin as the rhodium wears, while a palladium-based, nickel-free white gold is much kinder. If your skin reacts to metals, platinum is a safe choice, and so is a nickel-free white gold.
| Feature | Platinum | White gold |
|---|---|---|
| Colour | Naturally white, forever | Rhodium-finished white |
| Upkeep | None to keep its colour | Occasional replating |
| Wear | Displaces metal, buffs back | Slowly loses a little metal |
| Holding a stone | Very secure, deforms not cracks | Secure, a little more brittle |
| Weight | Denser and heavier | Lighter |
| Price | Around 40 to 50 percent more | More affordable |
| Sensitive skin | Naturally hypoallergenic | Depends on the alloy |
Platinum or gold, which should you choose?
There is no single winner, only the right metal for the piece and the person.
Choose platinum for a naturally white metal that needs no upkeep, holds a stone most securely, and suits sensitive skin, if you are happy to pay a premium for it. Choose white gold for a very similar look at a lower price, with a little rhodium replating over the years. And if you want warmth rather than a white metal, yellow or rose gold is the answer. All are precious metals that last.
This sits within our wider guide to gold, and if it is the claw setting that has you weighing platinum, our guide to bezel vs claw settings is worth a read too. We work in solid gold across the range and offer platinum on request, including for tennis pieces, rings and necklaces and pendants.
