24K vs 22K vs 18K Gold: What Is the Difference?

When purchasing gold jewellery, it is important to understand the difference between 24K, 22K and 18K gold. Gold purity affects the colour, durability, gold content, price and suitability of each jewellery piece.

Gold Purity Comparison

Gold Type Purity Common Marking Durability Common Use
24K Gold Approximately 99.9% 999 or 999.9 Softest Bullion and selected jewellery
22K Gold Approximately 91.6% 916 More durable than 24K Traditional and daily-wear jewellery
18K Gold 75% 750 Strongest of the three Fine jewellery and daily wear

What Is 24K Gold?

24K gold is the highest-purity gold commonly available. It normally contains approximately 99.9% pure gold and is often stamped 999 or 999.9.

It has a rich yellow colour and a high gold content. Because pure gold is naturally soft and malleable, 24K jewellery may scratch or bend more easily than lower-purity gold.

Best suited for

  • Gold bars and bullion
  • Investment gold products
  • Commemorative gold gifts
  • Selected high-purity jewellery

What Is 22K Gold?

22K gold contains approximately 91.6% pure gold and is commonly stamped 916. The remaining percentage consists of other metals added to improve strength and durability.

916 gold retains the rich yellow appearance associated with high-purity gold while being more suitable for jewellery construction than 24K gold.

Best suited for

  • Rings
  • Bracelets and bangles
  • Necklaces and chains
  • Earrings and pendants
  • Wedding and Si Dian Jin jewellery
  • Traditional and daily-wear gold jewellery

What Is 18K Gold?

18K gold contains 75% pure gold and is commonly stamped 750. The remaining 25% consists of other metals that increase durability and may influence the colour of the jewellery.

Depending on the alloy mixture, 18K gold may be produced in yellow, white or rose-coloured finishes. It is generally more resistant to scratching and bending than 22K or 24K gold.

Best suited for

  • Daily-wear jewellery
  • Gemstone and diamond settings
  • White or rose-coloured gold jewellery
  • Designs requiring greater structural strength

How Gold Purity Affects Colour

Higher-purity gold usually has a deeper and richer yellow colour because it contains a larger percentage of pure gold.

24K Gold

Deep, bright yellow appearance.

22K Gold

Rich yellow colour with slightly increased durability.

18K Gold

Softer yellow tone or white and rose-coloured variations.

Which Gold Is Most Durable?

In general, gold becomes more durable as additional alloy metals are added. This means 18K gold is usually stronger than 22K gold, while 22K gold is generally stronger than 24K gold.

Durability also depends on the design, thickness, weight and construction. A well-made solid 22K piece may be more durable than a very thin or hollow lower-purity design.

Which Gold Has the Highest Gold Value?

Higher-purity gold contains more pure gold per gram. Therefore, 24K gold normally has the highest intrinsic gold content, followed by 22K and then 18K gold.

The retail price of jewellery may also include workmanship, design, branding, stones and other charges. Buyback or trade-in value is usually based mainly on confirmed purity, gold weight and the applicable rate.
