How do they compare?
| Platinum | White gold | |
|---|---|---|
| Colour | Naturally white | Bright white from rhodium plating |
| Weight | Heavier | Lighter |
| Wear | Develops a soft patina | Plating wears and can be renewed |
| Upkeep | Polishing to restore shine | Replating over time |
| Cost | Higher | Lower |
Which suits an everyday ring?
Platinum suits people who want a heavy, low-maintenance ring. White gold suits people who prefer a lighter ring and a lower price, and are happy to have it replated.
Does the metal change how the diamond looks?
Both white metals show a diamond’s colour clearly, so pair them with a near-colourless or colourless grade.
