Is 9ct Gold Real Gold? One of the Most Common Questions We Get Asked
Across our Gold Reserves shops in Swansea, Llanelli and Cardiff, one of the questions we hear almost every day is, "Is 9ct gold actually real gold?"
The simple answer is yes, absolutely!
It's one of the biggest misconceptions people have about gold jewellery, so let's explain exactly what 9ct gold is and why it's recognised as genuine gold.
What Does 9ct Gold Mean?
Many people think that because 9ct gold isn't made from 100% pure gold, it somehow isn't "real" gold. This simply isn't true.
The word carat (ct) refers to how many parts out of 24 are pure gold.
So, 9ct gold means that 9 parts out of 24 are pure gold, with the remaining 15 parts made up of other metals.
This works out as:
-
9ct Gold = 37.5% pure gold
-
62.5% other metals
These additional metals are commonly copper, silver and zinc, which are added to improve the jewellery's strength and durability.
Why Isn't Jewellery Made From Pure Gold?
Pure gold (24ct) is beautiful, but it's also extremely soft.
If you made an engagement ring or wedding band from pure gold, it would scratch, bend and wear much more easily through everyday use.
That's why jewellers mix pure gold with other metals to create an alloy that's much stronger and better suited to everyday wear.
For many people, 9ct gold offers an excellent balance between durability, affordability and the timeless beauty of real gold.
What Does the 375 Hallmark Mean?
If you own a piece of 9ct gold jewellery, you'll usually find it stamped with the number 375.
This hallmark tells you the jewellery contains 37.5% pure gold, which is exactly the amount required for it to be legally sold as 9ct gold in the UK.
In fact, 37.5% is the lowest legal gold purity that can be described and hallmarked as gold in the UK.
So if your jewellery carries a 375 hallmark, you can be confident it's genuine gold.
What's the Difference Between the Different Gold Carats?
The main difference between gold carats is simply how much pure gold they contain.
Here's a quick guide:
| Gold Carat | Pure Gold Content | Hallmark |
|---|---|---|
| 9ct | 37.5% | 375 |
| 14ct | 58.5% | 585 |
| 18ct | 75% | 750 |
| 22ct | 91.6% | 916 |
| 24ct | 99.9% (approximately) | 999 |
As the carat increases, the amount of pure gold increases too.
This generally means the jewellery is:
-
More valuable because it contains more gold.
-
Softer than lower carat gold.
-
Richer in colour, particularly with yellow gold.
Lower carat gold, such as 9ct, is often more resistant to everyday knocks and scratches, making it a popular choice for rings and jewellery that's worn daily.
Why Does Carat Affect the Price of Gold?
This is something we explain regularly to customers selling their unwanted jewellery.
Because higher carat gold contains more pure gold, it's worth more based on its precious metal content.
For example, one gram of 18ct gold contains twice as much pure gold as one gram of 9ct gold.
That's why, when buying unwanted gold, the price paid per gram varies depending on the carat.
At Gold Reserves, we test every item individually before identifying its purity and calculating its value. The higher the gold content, the more the precious metal itself is worth, which is why higher carat jewellery generally achieves a higher price per gram.
Which Carat Is Best?
There isn't a single "best" choice—it depends on what you're looking for.
If you want jewellery that's durable, affordable and ideal for everyday wear, 9ct gold is an excellent option.
If you prefer a richer gold colour and a higher gold content, you may prefer 18ct or 22ct gold.
Each has its own advantages, and they're all genuine gold.
The Bottom Line
9ct gold is real gold.
It's legally recognised, hallmarked and one of the most popular choices for jewellery in the UK.
The difference between 9ct, 14ct, 18ct and higher carats isn't whether they're real gold—they all are. The difference is simply how much pure gold each contains.
