When it comes to choosing the right gold for you, it’s important to understand the differences between 24-carat and 18-carat gold. From purity and durability to price and uses, each type has its advantages and drawbacks.

Whether you're investing in gold bars or buying 

, understanding the differences between these two gold grades is essential. So let’s break it down to help you make an informed decision based on your priorities!

Let's explore the concept of gold fineness, otherwise known as 

The carat (ct) system is used to measure the fineness of gold. It indicates how many parts of gold are present out of 24 total parts. Pure gold is 24 carats (24ct), meaning it's 99.9% gold, with no other metals mixed in. 

Lower carat levels, such as 18ct, mean the gold is alloyed with other metals, like silver or copper, making it less pure but more durable. For example, 18ct gold is 75% pure, while 14ct is 58.5% pure. The higher the carat, the higher the gold content:

1-carat gold contains 1/24 parts (4.2%) pure gold

18-carat gold contains 18/24 parts (75%) pure gold

24-carat gold contains 24/24 parts (99.99%) pure gold

The carat scale measures gold purity in 1/24 steps, known as grades. 24-carat gold represents the highest purity level.

The colour of gold varies depending on its carat and the metals alloyed with it:

: Pure gold with a bright yellow hue, as no other metals are mixed.

: Contains 75% gold and is available in various colours depending on the alloys:

(mixed with palladium, silver, or nickel for a white finish)

Lower carat gold, like 9ct, often appears less vibrant and more muted in tone.

Different carats of gold have specific uses based on their purity and durability:

 (99.9% pure): Soft and malleable, used primarily for 

 in some cultures, maintaining a bright yellow hue with better durability than 24-carat.

, offering a balance of purity, durability, and colour variations depending on alloys (yellow, rose, or white).

: Less pure, more durable, and often used for 

Generally, 24-carat gold is considered too soft for most types of jewellery. Because it's made of nearly pure gold, it is malleable and prone to scratches and bending. This softness makes it unsuitable for everyday wear, especially for pieces like rings and bracelets that may get knocked during wear. Jewellers often opt for 18-carat or lower-carat gold for jewellery, as these alloys are mixed with other metals – adding strength and durability while retaining a luxurious appearance.

Popular investment-grade gold coins are highly sought after by investors due to their recognised value, global liquidity, and purity. Some of the most well-known investment-grade gold coins include:

(South Africa, fineness: 22 carats/91.67% pure gold)

(Canada, fineness: 24 carats/99.99% pure gold)

(Austria, fineness: 24 carats/99.99% pure gold)

(USA, fineness: 22 carats/91.67% pure gold)

(United Kingdom, fineness: 24 carats/99.99% pure gold as of 2013)

: 24-carat gold is more expensive due to its higher purity, while 18-carat gold is more affordable.
