A white gold ring is made from gold alloyed with white metals (such as nickel or palladium) and plated with rhodium to achieve its bright finish. Platinum is a naturally white metal that is denser, heavier and rarer than gold. Both metals are popular choices for engagement rings, but they differ in colour, durability, weight and cost.
### Key differences
- **Colour**: White gold requires rhodium plating to maintain its whiteness; platinum is naturally white and does not need plating.
- **Durability**: Platinum is denser and more resistant to wear. White gold is durable but may show wear faster and needs periodic re‑plating.
- **Weight**: Platinum is heavier and feels more substantial on the finger. White gold is lighter.
- **Cost**: Platinum is more expensive due to its rarity and density. White gold is generally more affordable.

### FAQs
**Does platinum scratch easily?** Platinum develops a patina rather than deep scratches; the metal is displaced, not lost.
**Is 18 ct white gold better than 9 ct?** 18 ct contains more pure gold and has a richer colour but is softer; 9 ct is harder and more affordable.
**Which metal is more hypoallergenic?** Platinum is naturally hypoallergenic. White gold may contain nickel unless alloyed with palladium.
