Yellow gold jewellery offers a beautiful spectrum of shades and strengths. When choosing a yellow gold engagement ring or wedding band, consider elements like colour depth, karats, and design to find your perfect fit. This guide will cover everything you need to know about yellow gold karats, helping you choose the ideal ring with confidence.
Understanding Gold Karats
Gold, in its purest form, is naturally soft, which makes it less durable than other precious metals. To enhance its strength and wearability, pure gold is often alloyed with other metals. This alloying process influences the colour and hardness of the precious metal.
Gold purity is measured in karats (k), representing the percentage of gold within the alloy. For instance, a 9k ring contains 37.5% pure gold, while a 24k ring is entirely pure gold.
While a higher karat denotes a greater gold content, it also means the gold is softer and more prone to scratching. The highest karat isn’t always the best choice for every piece. Depending on the alloy composition, certain karats may offer enhanced durability, flexibility, or hypoallergenic properties.

Choosing Between 18k and 14k Yellow Gold Rings
When searching for a yellow gold ring, most seek a balance between luxurious shine and long-lasting wearability.
18k yellow gold is the alloy of choice for most premium jewellers. With its higher gold content, 18k gold has a richer hue than 14k and is also less prone to breakage. In terms of hardness, both 14k and 18k gold measure similarly on the Vickers scale, meaning they share a similar resistance to scratching. However, 18k gold is less likely to corrode and has a higher elongation percentage, which means it’s more likely to bend than break—an important quality for securely holding gemstones.
Another benefit? 18k yellow gold is more hypoallergenic than 14k, making it a great choice for those with metal sensitivities.
Karats for Wedding and Engagement Rings
Engagement rings and wedding bands are worn every day, so they need to be durable enough to keep their lustre. Although 24k gold is beautiful, it is also softer, making 18k or lower karats a better choice for rings that will be worn daily. Alloyed gold rings are more scratch-resistant, so choosing 14k or 18k gold for wedding and engagement rings ensures they remain beautiful through years of wear.
If you plan to wear your ring regularly, selecting an 18k or lower karat will also help maintain its pristine condition.
