In the UK, 9ct gold is often better for everyday wear if you want durability and affordability, while 18ct gold offers a richer colour and higher gold content—but it can be softer and more prone to scratches.
### Is 9ct gold real gold?
Yes. 9ct gold is 37.5% pure gold, alloyed with metals for strength. This makes it harder and more affordable than higher-karat gold.
### Is 18ct gold better than 9ct?
“Better” depends on your priorities:
- 9ct : tougher, lower cost, ideal for daily wear
- 18ct : richer colour, higher gold content, premium feel
### Which scratches more: 9ct or 18ct?
18ct gold can scratch more easily because it contains a higher percentage of soft pure gold. 9ct gold’s higher alloy content makes it more resistant to scratches.
