22K vs 24K vs 18K Gold: Which Should You Buy? — AT Jewels

Saturday, 17 October 2026 — a weekend read from our counter to yours: 22K vs 24K vs 18K gold — which one should you actually buy, and why.

What the karat number actually means

Gold is measured in karats out of 24. Pure gold is 24 karat — but pure gold is also very soft, which is why almost nothing you wear every day is made from it. To make gold strong enough to hold a shape, a clasp or a diamond, it is mixed with small amounts of other metals like copper, silver or zinc. The karat simply tells you how much of the final piece is gold:

24K — 99.9% pure (stamped 999). The purest, deepest-yellow gold. Soft and easily scratched or bent, so it is used mainly for coins, bars and investment gold rather than jewellery you'll wear.
22K — 91.6% pure (stamped 916). The classic choice for Indian gold jewellery — chains, bangles, necklaces, traditional wedding sets. A beautiful warm colour, durable enough for regular wear, and the strongest resale value.
18K — 75% pure (stamped 750). More everyday-tough because of the higher alloy content, and the best setting for diamonds and coloured stones. It also comes in more shades — yellow, rose and white gold — so it's popular for modern and daily-wear designs.

Which should you buy — by purpose

Buying to save or gift value? Go with 24K coins or bars. You're paying almost entirely for gold, with little lost to making, so it's the cleanest way to hold value.
Buying classic jewellery — bangles, chains, a wedding set? 22K is the time-tested answer in India. It keeps that rich traditional colour, wears well, and when you exchange or sell it later, 22K fetches the best return.
Buying diamond jewellery, daily-wear rings or delicate modern designs? 18K is usually the smarter pick. It holds stones more securely, resists daily knocks better, and lets jewellers create finer, more intricate work — including rose and white gold looks.

How purity affects price (and resale)

Naturally, higher purity means more gold per gram, so 24K costs the most per gram, then 22K, then 18K. But the final bill isn't only about purity — making charges, design complexity and 3% GST all add on top. A lighter 18K piece with simple making can cost far less than a heavy 22K one. When it comes to resale or exchange, 22K and 24K hold value best because buyers can re-refine the gold easily; 18K is wonderful to wear but generally fetches a little less on exchange. The honest rule of thumb: buy higher purity when value is the point, and buy for durability and design when you'll actually wear it a lot.

Always check the hallmark

Whatever karat you choose, look for the BIS hallmark and the 6-digit HUID stamped on the piece. The purity mark confirms what you're paying for — 916 for 22K, 750 for 18K, 999 for 24K. It's your simplest protection and it costs you nothing to ask for.

Frequently asked

Which gold is best for daily-wear jewellery, 22K or 18K?
For pieces you'll wear every day — especially anything with diamonds or fine detail — 18K is usually best because the higher alloy content makes it more scratch- and knock-resistant and holds stones securely. For traditional plain-gold jewellery and the best resale, 22K is the classic choice.

Is 24K gold good for jewellery?
24K is the purest gold (99.9%) but it is soft and bends or scratches easily, so it isn't ideal for jewellery you'll wear often. It's better suited to coins and bars if your goal is saving. Most wearable Indian jewellery is made in 22K or 18K.

Does higher karat mean better resale value?
Generally yes — 24K and 22K hold value best on exchange because the gold is easy to re-refine, which is why 22K is the traditional pick in India. 18K is wonderful to wear and durable, but usually fetches a little less on resale. Buy higher purity when value is the goal, and buy for durability and design when you'll wear it a lot.
