What does karat mean? – Understanding gold karat in engagement rings
When shopping for a gold engagement ring, you’ll often come across terms like 9 karat, 14 karat, or 18 karat. But what do these numbers actually mean? And which option best fits your needs? In this guide, we explain what karat means, the types available, and the pros and cons of each.
What is karat?
Karat refers to the amount of pure gold present in a gold alloy. Gold is almost always mixed with other metals (such as copper, silver, or palladium) to make it stronger and more workable. The higher the karat, the more pure gold the jewelry contains.
9 karat gold
Advantages:
- Affordable
- Harder and more durable than higher karats
- Wear-resistant and suitable for everyday use
Disadvantages:
- Less warm in color
- Higher risk of allergic reactions (due to more alloy metals)
- Not officially recognized as real gold in the Netherlands until 2019
14 karat gold
Advantages:
- Excellent balance of price, durability, and color
- Popular in the Netherlands and Belgium
- Suitable for everyday wear
- Lower allergy risk than 9 karat
Disadvantages:
- Softer than 9 karat
- Slightly more expensive
18 karat gold
Advantages:
- Rich, luxurious gold color
- High gold content (lower allergy risk)
- Common in high-end jewelry
Disadvantages:
- Softer, more prone to scratches and dents
- Considerably more expensive than 14k and 9k
- Less suited for rings worn frequently
Which karat should you choose?
That depends on your budget, lifestyle, and personal preferences:
- 9k: strong and affordable
- 14k: best all-around choice
- 18k: elegant and traditional
Do you want an engagement ring with a luxurious look that’s still durable enough for daily wear? Then 14k is usually the ideal middle ground. Want something that really stands out and carries high gold value? Then 18k may be the better choice.
In conclusion
No matter which karat you choose, proper care will greatly extend the lifespan of your jewelry. Remove your ring during heavy-duty tasks, store it safely, and have it inspected regularly by a jeweler.
That way, you’ll enjoy your gold engagement ring for many years to come — one that truly reflects your style.

FAQ
Gold content: 9ct = 37.5%, 14ct = 58.5%, 18ct = 75%
Gold karat refers to purity. Diamond karat refers to weight (1 ct = 0.2 g).
14 karat — the ideal balance between durability, price and looks.
In the United States, 9 karat gold is not officially recognized as real gold under federal law. According to the Federal Trade Commission (FTC) guidelines, gold jewelry must contain at least 10 karats (41.7% pure gold) to be legally marketed as "gold." Anything below 10K cannot be labeled or sold as gold in the U.S.
This standard has been in place for many decades, aligning with long-standing consumer protection regulations. So, while 9K gold is common and accepted in countries like the UK and Australia, it does not meet the legal threshold to be called gold in the United States.
Yes — it’s strong enough for everyday use and keeps its shine well.
Not really — it’s softer and more prone to wear and scratches.
Yes — especially with 9 carat due to the higher content of metals like nickel or copper. 14 and 18 carat reduce this risk. The best option is still platinum.
Yes, karat has the same meaning for white, yellow, and rose gold. It tells you how much pure gold is in the metal – not its color.
Examples:
- 14 karat = 58.5% pure gold
- 18 karat = 75% pure gold
Color differences come from the additional metals:
- Yellow gold: gold mixed with silver and copper
- White gold: gold alloyed with palladium or nickel (typically rhodium plated)
- Rose gold: gold with a high copper content for a pinkish hue
A 14 karat ring always contains 58.5% gold, regardless of the color. Only the appearance and alloy composition are different.
