Platinum vs White Gold: What Jewellery Buyers Actually Need to Know

Most people cannot tell platinum from white gold just by looking. That is normal. They appear almost identical to the naked eye.

However, they are not the same. The differences are significant—especially if you are purchasing a ring that you intend to wear daily for decades.

Here is what you need to know.

The Short Answer

Platinum is denser, more durable, and more expensive than white gold. It does not require rhodium plating to maintain its white appearance. Over time, platinum develops a natural matte patina rather than wearing down. White gold requires replating every 12 to 18 months to sustain its colour.

If you desire a metal that will outlast you and never need replating, purchase platinum. If you prefer a lower price and are willing to accept occasional maintenance, opt for white gold.

The Confusion: Platinum vs White Gold

The confusion arises because both metals appear silver-white. However, their composition and behaviour are completely different.

Platinum is a pure metal. Most jewellery comprises 90% to 95% platinum, combined with a small amount of ruthenium, cobalt, or iridium for hardness. It is naturally white. It remains white.

White gold starts as yellow gold. Jewellers mix yellow gold with palladium, silver, or nickel to achieve a white appearance. Then they coat it with rhodium—a hard, white metal from the platinum family. That rhodium layer provides white gold with its bright white shine. However, it wears off.

This is the single most significant difference that jewellers often do not explain.

Purity Marks: Pt950 vs Pt900 vs Pt850

Platinum jewellery carries purity marks, which indicate the exact amount of platinum in the piece.

Higher platinum content results in a softer metal. Pt950 is standard for most rings because it balances purity with durability. Pt900 is slightly harder and holds gemstones more securely.

In comparison to gold, 14K gold is only 58% gold. 18K gold is 75%. Platinum jewellery is almost always 90% to 95% pure platinum.

Why Platinum Costs More

Three reasons.

First, raw platinum is expensive. As of early 2026, platinum trades around £1,800 per ounce. Gold is approximately £2,000. However, that is not the complete picture.

Second, platinum is denser. A platinum ring weighs approximately 60% more than an identical ring in 14K gold. You are purchasing more metal by weight.

Third, platinum is more difficult to work with. It requires higher temperatures for casting and shaping. Polishing takes longer. Labour costs are higher.

A platinum engagement ring typically costs 30% to 50% more than an identical 14K white gold ring.

Durability: Does Platinum Scratch?

Yes, platinum does scratch. However, the manner in which it scratches is different.

White gold gets scratched, and the scratch appears as a bright line against the rhodium coating. It appears damaged.

Platinum gets scratched, but the metal displaces. The scratch becomes a small bump rather than a missing line. Over time, platinum develops an even, matte patina. Many buyers prefer this appearance.

More importantly, platinum does not lose metal when scratched. White gold loses a small amount of rhodium and gold with each scratch and each polishing.

A platinum ring will weigh almost the same in 50 years as it did on the day of purchase. A white gold ring will be lighter.

Care and Maintenance

Platinum:

• Clean with warm water, mild dish soap, and a soft toothbrush
• Professionally polish once every few years if you wish to restore the shine
• No replating needed—ever

White gold:

• Same cleaning method
• Requires rhodium replating every 12 to 18 months
• Each replating costs £50 to £100

When to Choose Platinum

Platinum is suitable for:

• Engagement rings worn daily
• Wedding bands for individuals with metal allergies (platinum is hypoallergenic; white gold with nickel is not)
• Pieces intended to be passed down to children or grandchildren
• Anyone who does not wish to deal with replating

When to Skip Platinum

White gold is more appropriate for:

• Budget-conscious buyers
• Trendy pieces that you may not wear in 10 years
• Earrings and necklaces that do not experience heavy wear

The Bottom Line

Platinum is the more durable, lower-maintenance, and more expensive option. White gold is the budget-friendly choice that necessitates regular upkeep.

Neither is "better." They simply fulfil different priorities.
