10K, 14K or 18K Gold: A Simple Guide

Gold jewellery is almost never pure gold. Pure 24K gold is too soft for rings and earrings, so it is mixed with other metals to make it stronger and to create different colours. The karat number tells you how much of the piece is real gold.

What the numbers mean

• 10K gold: 41.7% gold (stamped 417). The most durable and the most affordable.
• 14K gold: 58.5% gold (stamped 585). The favourite balance of rich colour, strength and value.
• 18K gold: 75% gold (stamped 750). The deepest colour and the most luxurious feel, ideal for diamonds.
• 925 sterling silver: 92.5% silver. Bright, light and the most budget-friendly choice.

Which is best for everyday wear?

The lower the karat, the harder the metal. 10K and 14K gold resist scratches and bending better, which makes them great for rings and earrings you wear every day. 18K gold is a little softer but has a richer, warmer glow, which is why it is a classic choice for engagement rings and special pieces.

Yellow, white or rose?

The colour comes from the other metals in the mix. Yellow gold is the classic warm tone. White gold is usually finished with a bright rhodium coating for a silvery look. Rose gold gets its pink blush from copper. All three come in the same karats, so you can choose the colour you love.

Our quick advice

For everyday sparkle on a budget, choose 925 silver or 10K gold. For the best all-round choice, go with 14K. For a heirloom or bridal piece, choose 18K. If you have sensitive skin, ask us about the metal mix before ordering and we will help you pick the most comfortable option.
