22KT vs 18KT Gold: What Karat Should You Actually Buy?
22KT vs 18KT Gold: What Karat Should You Actually Buy?
Last updated: 09 July 2026
Stand at a jewellery counter in India and you'll face a question that quietly decides how much you spend, how your jewellery wears, and how it looks: 22KT or 18KT gold? Most buyers default to 22KT out of habit but 18KT gold has become one of the fastest-growing choices in the country, and for good reasons.
This guide compares 22KT and 18KT gold honestly purity, durability, price, colour options and best uses. By the end, you'll know exactly which karat suits which purchase, so you can buy with a clear reason rather than out of habit.
22KT or 18KT: The Short Answer
If you want maximum purity and traditional value, choose 22KT gold. If you want greater durability, a wider range of designs and colours, and a lower price, choose 18KT gold. Neither is "better" ; they suit different purposes.
In simple terms: 22KT gold is 91.6% pure, soft, and ideal for traditional Indian jewellery. 18KT gold is 75% pure, harder, and ideal for diamond-studded pieces, intricate modern designs, and everyday wear. The right karat depends on the piece and how you'll use it.
What "Karat" Actually Means in Gold
Karat measures the purity of gold by how much of the metal is pure gold versus alloyed with other metals. Pure gold is 24 karat, but pure gold is too soft to hold a jewellery shape, so it is always mixed with metals like copper, silver or zinc for strength.
22KT gold means 22 parts gold out of 24, or 91.6% pure which is why it carries the "916" hallmark. 18KT gold means 18 parts out of 24, or 75% pure which is why it carries the "750" hallmark. So when you see 18kt 750 gold marked on a piece, the two numbers say the same thing: 18 karat, 75% pure gold. The remaining 25% is alloy metal, and it's that alloy that gives 18KT its extra hardness.
22KT vs 18KT Gold: The Full Comparison
22KT gold contains 91.6% pure gold (916 hallmark), while 18KT gold contains 75% pure gold (750 hallmark).
Due to its higher gold content, 22KT gold is softer and more prone to scratches, whereas 18KT gold is harder and better suited for regular wear.
22KT gold generally has a higher price per gram because of its greater purity, while 18KT gold is comparatively more affordable.
22KT gold is commonly preferred for traditional jewellery and plain gold ornaments, while 18KT gold is ideal for diamond jewellery, gemstone settings, and intricate contemporary designs.
22KT gold is mainly available in the classic yellow gold colour, whereas 18KT gold is offered in yellow, white, and rose gold options.
Because it contains more pure gold, 22KT jewellery typically has higher resale value than 18KT jewellery.
Why 18KT Gold Has Become So Popular
For years, Indian buyers overwhelmingly chose the 22KT. Today, 18KT gold jewellery is one of the fastest-growing categories and three reasons explain why.
First, durability. The higher alloy content makes 18KT harder and more scratch-resistant, which suits modern, active lifestyles and everyday wear far better than soft 22KT.
Second, design freedom. 18KT's strength lets craftsmen create intricate, delicate and contemporary designs that soft 22KT cannot hold as well and it grips diamonds and gemstones far more securely, which is why almost all studded jewellery is made in 18KT.
Third, value and variety. The 18kt price per gram is lower than 22KT because there is less pure gold in it, making beautiful gold jewellery more accessible. It also comes in more colours which brings us to the next point.
18KT Yellow, White and Rose Gold: Understanding the Colours
One of the biggest advantages of 18KT gold is colour. Because 25% of the metal is alloy, changing the alloy mix changes the colour, something far harder to achieve in high-purity 22KT.
18kt yellow gold is the classic, warm gold colour, alloyed mainly with copper and silver. It's the traditional choice and pairs with every skin tone.
18kt white gold is alloyed with white metals such as palladium or nickel to create a silvery-white finish, often with a rhodium plating for extra brightness. It's a popular, modern choice and a beautiful setting for diamonds.
18KT rose gold gets its warm pink hue from a higher copper content in the alloy. It has a soft, romantic look that suits contemporary designs and because rose gold uses more copper, the 18kt rose gold price can differ slightly from yellow gold, so always check the current rate for the specific colour.
This three-colour range is unique to 18KT in practical terms, and it's a major reason designers and buyers love it.
Which Karat Should You Choose? A Purchase-by-Purchase Guide
The best way to decide is to match the karat to the specific piece.
Choose 22KT gold for: traditional bridal jewellery, plain gold chains and bangles, temple jewellery, and gold bought partly as investment. Here, purity and resale value matter most, and the softer metal is fine because the designs are robust.
Choose 18KT gold for: diamond and gemstone jewellery (the secure stone setting is essential), intricate or contemporary designs, daily-wear pieces that take knocks, white or rose gold pieces, and lighter everyday items. An 18 kt gold anklet, for example, benefits from 18KT's hardness because anklets take constant friction and impact. A modern gold necklace set 18kt with stonework will hold its detail and stones far better than the same design in 22KT.
A practical rule: plain, traditional and investment-led pieces lean 22KT; designed, studded, coloured and everyday pieces lean 18KT.
Price, Hallmark and What to Check Before You Buy
Whatever karat you choose, a few checks protect your money.
On price: the 18kt price per gram is lower than 22KT because it contains less pure gold but remember the final cost also includes making charges and GST. 18KT can also carry higher making charges when the design is intricate, so always ask for an itemised breakdown: gold rate for that karat, weight, making charges and GST shown separately.
On purity: every piece must carry a BIS hallmark. A genuine 18KT piece shows the "18K750" mark, and a 22KT piece shows "22K916", alongside the BIS logo and a 6-digit HUID. Verify the HUID on the BIS Care app before paying.
On resale: 22KT returns more pure-gold value at resale, while 18KT returns less because of its lower purity factor if resale value matters to you.

Frequently Asked Questions
1. Is 18KT gold real gold?
Yes. 18KT gold is genuine gold that is 75% pure, mixed with 25% alloy metals for strength. It carries the "750" hallmark, which is why it is also called 18kt 750 gold. It is real, BIS-hallmarked gold simply at a different purity than 22KT.
2. Is 18KT or 22KT gold cheaper?
18KT gold has a lower price per gram than 22KT because it contains less pure gold (75% versus 91.6%). However, the final cost of any piece also depends on its weight, design and making charges, so always compare itemised prices.
3. What is the difference between 18KT yellow, white and rose gold?
All three are 75% pure 18KT gold; the colour comes from the alloy mix. 18kt yellow gold uses copper and silver for the classic warm tone, 18kt white gold uses white metals for a silvery finish, and rose gold uses more copper for a pink hue.
4. Which karat is better for diamond jewellery?
18KT gold is better for diamond and gemstone jewellery. Its higher alloy content makes it harder and stronger, so it holds stones more securely than softer 22KT gold. This is why most studded and diamond jewellery is made in 18KT.
5. Does 18KT gold have a BIS hallmark?
Yes. 18KT gold jewellery must carry a BIS hallmark just like 22KT. Look for the "18K750" purity mark alongside the BIS logo and a 6-digit HUID, and verify the HUID on the BIS Care app before buying.
6. Is 18KT gold good for daily wear?
Yes. 18KT gold is well suited to daily wear because it is harder and more scratch-resistant than 22KT. Everyday pieces such as an 18 kt gold anklet, rings and lightweight chains benefit from this extra durability.
7. Can 18KT gold change colour over time?
18KT gold itself does not rust, but over time it may appear slightly dull due to exposure to sweat, perfumes, dust, or chemicals. Regular gentle cleaning and proper storage help maintain its shine and original finish for years.
8. Is 18KT gold suitable for sensitive skin?
Yes, for most people. High-quality BIS-hallmarked 18KT gold jewellery is generally skin-friendly because it contains a high percentage of pure gold. However, people with metal sensitivities should check the alloy composition, especially in white gold pieces.
9. Why is 18KT gold popular in modern jewellery?
18KT gold offers a balance between purity, durability, and design flexibility. Its strength allows jewellers to create detailed, lightweight, contemporary, and stone-studded designs that may not hold as securely in softer higher-purity gold.
10. Is 18KT gold suitable for gifting?
Yes. 18KT gold jewellery makes an excellent gift because it combines beauty, durability, and affordability compared to higher-purity gold. Modern pendants, rings, bracelets, and personalised jewellery pieces in 18KT gold are especially popular gifting choices.
