14K or 18K gold: what’s the difference?
Karat measures gold content. 18K has a higher gold content and a richer colour. 14K contains more alloy metals, making it harder-wearing and more affordable.
| Karat | Gold content | Stamp | Best for |
|---|---|---|---|
| 18K | 75% | 750 | Engagement rings and heirloom pieces |
| 14K | 58.5% | 585 | Everyday wear, studs, bracelets and pendants |
Yellow, white or rose gold?
The colour comes from the metals alloyed with gold.
- Yellow gold: warm and traditional, and flatters warmer diamond colours
- White gold: rhodium plated for a bright white finish that can be renewed
- Rose gold: copper gives the pink, so its colour doesn’t rely on plating
Which gold jewellery can you buy?
