22K vs 24K Gold: What’s the Difference?

“Should I buy 22 carat or 24 carat?” is the first question most people face at the jeweller. The answer depends on why you’re buying. Here’s what the numbers mean, how they affect price and durability, and how to choose.

What “karat” actually measures

Karat (written K or KT, and sometimes “carat” in India) is a measure of gold purity — how much of the metal is actually gold versus other metals mixed in. The scale runs to 24, so each karat is 1/24th of the whole:

That’s why you’ll hear jewellers say “916” for 22K and “999” for 24K — those numbers are literally the purity (91.6% and 99.9%) with the decimal dropped.

24K gold: pure, soft, and mainly for investment

24-karat gold is as pure as gold practically gets — 99.9%. It has the deep, slightly orange-yellow colour people associate with “real gold”. Because nothing is added to harden it, though, 24K is very soft: it scratches, bends and dents easily. That makes it a poor choice for rings or bangles you’ll wear daily, but an excellent choice for coins, bars and investment, where purity is the whole point and the piece isn’t taking daily knocks.

22K gold: the Indian jewellery standard

22-karat gold is 91.6% gold, with the remaining ~8.4% made up of harder metals like copper, silver or zinc. That small amount of alloy makes a big practical difference: the metal becomes tough enough to hold intricate designs and survive everyday wear, while still looking richly golden. This is why 22K is the default for traditional Indian gold jewellery — necklaces, bangles, and wedding sets.

18K and 14K: when durability matters most

18K (75% gold) and 14K (58.3%) contain still more alloy, making them harder and more scratch-resistant, with a slightly paler colour. They’re popular for rings, diamond and gemstone settings, and pieces worn every day, because the higher alloy content grips stones securely and resists deformation. They also cost less per gram, since less of the weight is gold.

How the price relates

Because price tracks purity, the rates move together in fixed proportion. If 24K is the reference:

• 22K ≈ 91.6% of the 24K rate (0.916 × 24K price)
• 18K ≈ 75% of the 24K rate (0.75 × 24K price)

So on a day when 24K gold is, say, ₹7,000 per gram, 22K works out to roughly ₹6,412 and 18K to about ₹5,250 per gram — before making charges and GST.

Which should you buy?

Choose 24K if…

You’re buying gold as a store of value or investment — coins, bars, or gifting pure gold. You get maximum gold for your money and easy resale, and you don’t care about wear because it won’t be knocked about.

Choose 22K if…

You want traditional jewellery that looks unmistakably gold and will be worn on occasions. It’s the sweet spot of purity and durability, and it holds strong resale value in India.

Choose 18K/14K if…

You want everyday or stone-set jewellery that resists scratches, or you want a lower price point. Ideal for rings and diamond jewellery.

A note on resale

When you sell gold back, the jeweller pays for the gold content, not the making charges you originally paid. Higher-purity gold (22K, 24K) therefore tends to retain value better in resale than lower-karat pieces, and coins/bars usually fetch closer to the pure-gold rate than jewellery. Keep your hallmark certificate — it makes resale simpler and fairer.

Quick recap

• 24K = 99.9% pure, soft — best for coins & investment.
• 22K = 91.6% pure, durable — India’s jewellery standard.
• 18K/14K — harder and cheaper, great for daily wear and stone-set pieces.
• Prices scale with purity; always factor in making charges + GST for the real cost.
