What 18K means
Eighteen parts gold. Six parts alloy.
Gold purity is measured in 24 parts. In 18 karat gold, 18 of those parts are gold and six are other metals. That gives 18K its 75% gold content.
You may also see the number 750 on 18K jewellery. It expresses the same purity as 750 parts of gold per 1,000.
Purity with purpose
Why 18K works in fine jewellery.
Pure gold is naturally soft. Mixing it with other metals changes its strength, colour and working qualities while preserving a high gold content.
Support for wear
The alloy adds durability compared with pure gold, making 18K a practical choice for many fine jewellery designs.
Room for detail
Its balance of purity and strength supports precise forms, stone settings and detailed Italian jewellery design.
The karat scale
How 18K compares with other gold purities.
Karat describes gold content, not overall design quality. A higher number means more gold and less alloy.

One purity, different tones
18K gold comes in more than one colour.
The gold content stays at 75%. The alloy recipe changes the colour and can also change how the surface is finished.
- Yellow gold
- Its warm colour stays closest to the natural appearance of pure gold.
- White gold
- White metals create a paler tone. Many white gold pieces also use rhodium plating for a brighter finish.
- Rose gold
- A higher proportion of copper in the alloy creates its pink or rose colour.
Wear it well
Simple care for 18K gold.
The right care depends on the whole piece, especially its stones, settings and surface finish.
Remove
Remove fine jewellery before swimming or using household cleaners. Apply perfume and cosmetics before putting jewellery on.
Separate
Use a lined box or soft pouch so pieces do not rub against each other and create avoidable scratches.
Wipe
Start with a soft, lint-free cloth. Ask the team before using chemical or ultrasonic cleaners on stone-set, plated or delicate pieces.
18K gold questions, answered.
Clear answers to the questions customers ask most often.
Is 18K gold real gold?
Yes. 18K gold is real gold made from 18 parts gold out of 24, which equals 75% pure gold.
What does 750 mean on gold jewellery?
750 is a fineness mark. It means 750 parts out of 1,000 are pure gold, which is the same purity as 18 karat gold.
Can 18K gold be worn every day?
18K gold is widely used for fine jewellery and is more durable than pure gold. It can still scratch or dent, and wear depends on the design, setting and how the piece is used.
Does 18K gold tarnish?
Gold is resistant to corrosion, but the alloying metals, surface finish and everyday residue can affect a piece's appearance. Care requirements also vary when diamonds, pearls or coloured stones are present.
What is the difference between 18K and 22K gold?
22K gold contains about 91.7% gold, while 18K contains 75%. The additional alloy in 18K gives jewellery more support for detailed shapes and settings.
Is 18K gold better than 14K gold?
Neither is universally better. 18K has a higher gold content and usually a richer gold colour. 14K contains more alloying metal. The right choice depends on the look, design and how the piece will be worn.
How should I clean 18K gold jewellery?
For a simple gold piece, start with a soft, lint-free cloth. Care can change when a piece includes stones, pearls, plating or delicate settings, so ask a jeweller before using chemical or ultrasonic cleaners.
