22K vs 24K Gold: The Differences Explained

When you buy gold in India, the first decision is karat: 22K or 24K. The choice affects purity, price, durability and what the gold is good for. This guide explains the difference in plain terms so you buy the right purity for your purpose.
What the karat number means
Karat measures purity out of 24. 24K is 99.9% pure gold; 22K is 91.6% pure (the rest being metals like copper and silver for strength). That is why hallmarked 22K carries the '916' stamp.
Durability
Pure 24K gold is soft and dents or scratches easily, making it unsuitable for everyday jewellery. The alloy in 22K makes it harder and more durable, which is why ornaments are usually 22K.
Price difference
24K costs more per gram than 22K because it is purer. When comparing prices, always compare the same karat — a 24K quote will naturally be higher than a 22K quote for the same weight.
Best use for each
Choose 24K for coins, bars and investment where purity and resale value matter most. Choose 22K for jewellery you will wear, where durability matters.
- 24K (999) → coins, bars, investment
- 22K (916) → daily-wear jewellery
- Always look for the BIS hallmark
Hallmarking
Regardless of karat, insist on BIS hallmarked gold. The hallmark certifies the purity you are paying for and protects you at resale.
