When buying gold jewellery in Dubai, one of the first choices you will face is the karat — the measure of gold purity. The two most popular options in the UAE are 22 karat and 18 karat gold. Understanding the difference will help you make a confident, informed choice.
What Is Karat?
Pure gold is 24 karats (24K), meaning 24 parts out of 24 are gold. Because pure gold is too soft for everyday jewellery, it is alloyed with other metals to increase durability. The karat number tells you how many parts out of 24 are pure gold.
22 Karat Gold
22K gold contains 91.6% pure gold. It has a deep, rich, warm yellow colour that is immediately recognisable as classic gold. The remaining 8.4% is typically silver and copper. Best for traditional jewellery, bangles, chains, and necklaces — extremely popular across the Gulf region for its cultural resonance and investment value.
18 Karat Gold
18K gold contains 75% pure gold. The remaining 25% alloy can be adjusted to produce yellow, white, or rose gold. Best for diamond-set jewellery, engagement rings, and fine contemporary pieces — the higher alloy content makes 18K harder and more resistant to scratching.
