Gold karat is one of the most important factors to consider when choosing jewellery, as it determines the purity, durability and appearance of the gold. Whether you're selecting an engagement ring, wedding band, or pendant, understanding gold karat ensures you make an informed decision suited to your style and lifestyle.

Gold karat refers to the measure of gold purity in a piece of jewellery. A common question is, “carat or karat?” – in fine jewellery, karat (K) indicates gold purity, while carat (ct) measures gemstone weight. Pure gold is 24K, but since it’s too soft for everyday wear, it’s often alloyed with other metals for strength. For engagement rings, popular choices include 18K and 14K gold, balancing beauty and durability.

Pure gold is 24 karats, meaning it contains 99.9% gold with no added metals. While 24K gold is highly valued for its purity and rich yellow colour, it is soft and prone to scratching, making it less suitable for everyday jewellery like engagement rings.

Gold comes in various levels of purity, with 10K, 14K, 18K, and 24K being the most common. The “K” stands for karats, measuring the gold content within each piece.

• 10K Gold – Contains 41.7% gold and is the hardest due to a higher percentage of alloy metals, making it durable and affordable. However, it has a paler colour and lower value.

• 14K Gold – With 58.3% gold, 14K strikes a balance between durability and richness in colour. It’s popular for jewellery but may still tarnish over time.

• 18K Gold – Made with 75% gold, 18K is valued for its warm, luxurious hue while being durable enough for everyday wear. At Queensmith, we use 18K gold because it offers the best combination of beauty, purity and resilience, ideal for engagement rings.

• 24K Gold – Pure gold (99.9%), with a rich yellow colour but very soft, making it impractical for daily wear.

Queensmith offers 18K gold for a perfect balance of beauty and durability, ensuring your ring remains stunning and strong over time.

There’s no strict rule about the karat of gold an engagement ring should be, but most engagement rings are crafted in 10K to 18K gold. For those seeking the best balance of beauty, durability and luxury, 18K gold is often the ideal choice. With 75% gold content, 18K offers a warm, rich colour that enhances the ring’s elegance while maintaining the strength needed for daily wear. Its higher gold purity means it’s less likely to tarnish compared to lower-karat options and it carries a more premium feel.

While 10K and 14K gold are durable and cost-effective, they contain higher alloy content, making them harder and more resistant to scratching but with a paler colour. In contrast, 18K’s closer-to-pure composition strikes the right balance of durability and visual appeal, making it an ideal choice for a ring that symbolises lasting commitment and beauty.

Gold engagement rings come in a variety of colours, each achieved by alloying pure gold with other metals. While yellow, white and rose gold are the most popular, unique options like black, green, blue and purple gold provide striking alternatives for those seeking something different.

Yellow gold is the most traditional gold colour, prized for its warm, rich hue that reflects pure gold’s natural appearance. Created by alloying gold with metals like copper and silver, yellow gold has a timeless appeal and works beautifully with most gemstones, especially warmer tones like yellow sapphires or rubies. It’s also one of the easiest gold colours to maintain due to its minimal plating requirements.

White gold offers a sleek, modern look, achieved by alloying gold with palladium or nickel and plating it with rhodium for a bright, silvery finish. Its neutral tone pairs well with nearly all gemstones, especially diamonds, enhancing their brilliance. White gold requires rhodium re-plating every few years to maintain its colour but remains a favourite for its versatility and affordability compared to platinum.
