18k Gold vs. 24k Gold: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 6, 2024
18k gold contains 75% gold and 25% alloy, offering durability and less purity, while 24k gold is 100% pure gold, softer and more suitable for investment.

Key Differences

18k gold is composed of 75% gold and 25% other metals, like copper or silver, making it more durable and resistant to scratches. 24k gold, on the other hand, is pure gold with no additional metals, which gives it a richer, more vibrant yellow color but makes it softer and more prone to scratching.

The appearance of 18k gold is slightly less vibrant than 24k gold due to its alloy content. It has a rich yellow color but can also be found in rose gold or white gold varieties. 24k gold is the brightest and most intense version of gold, with a deep, saturated yellow hue that reflects its purity.

18k gold is more durable and suitable for everyday wear, as the added alloys provide strength and hardness. In contrast, 24k gold is much softer and more malleable, making it less ideal for daily wear jewelry and more prone to warping and scratching.

18k gold is widely used in jewelry, especially in regions where higher gold content is preferred, balancing durability with a high gold content. 24k gold, being the purest form of gold, is often used in investment gold bars, coins, and in certain cultures for ceremonial jewelry.

In terms of price, 18k gold is generally less expensive than 24k gold. This is because 24k gold is pure gold, and gold is priced by its weight. The added alloys in 18k gold reduce the overall cost, making it a more affordable option for jewelry.
