22K vs 18K Gold: Which Is Better for Jewellery?

For plain gold jewellery that you want to hold its value, 22K is better. For diamond and gemstone pieces, and for rings you wear every day, 18K is better. 22K is 91.6% gold and softer; 18K is 75% gold, noticeably harder, and holds stones far more securely.

So the real question isn't which karat is superior. It's what you are buying. A solitaire ring and a pair of temple-style bangles need different metals.

What separates the two karats

Every 100 grams of 22K jewellery holds about 91.6 g of pure gold. The same weight of 18K holds 75 g. The other 25% in 18K is a mix of metals such as copper, silver, zinc or palladium, chosen for hardness and colour. That extra alloy changes four things.

• Hardness. 18K resists scratches and bending much better. Claws and prongs keep their grip.
• Colour. 22K has the rich yellow most Indian families expect. 18K can be made yellow, white or rose, which is why modern designs favour it.
• Price per gram. 18K costs roughly a fifth less per gram than 22K, because there is less gold in it.
• Resale value. When you sell, you are paid for pure gold content. 18K returns less per gram.

Piece by piece, which karat wins?

Here is how the choice usually plays out across the pieces people buy in Dubai.

For ring shopping specifically, our gold ring buying guide covers sizing, band thickness and settings.

Why diamond jewellers nearly always use 18K

A diamond is held by tiny claws of metal pressed over its edge. In soft 22K those claws slowly open with everyday knocks against doors, handbags and desks. In 18K they stay put. That is the main reason international diamond jewellery is made in 18K, stamped 750.

White gold is the other reason. You can't make a convincing white metal from 22K because there isn't enough room for whitening alloys. 18K leaves a quarter of the mix free for them, and the piece is then usually plated with rhodium for a bright finish. Our guide to 750 gold and how it is stamped explains the marks you will see.

One practical point for travellers: when you buy a diamond piece, ask the invoice to show gold weight and stone weight separately. That matters for pricing and for Indian Customs. See our guide to bringing diamond jewellery from Dubai before you fly.

What the price difference looks like

Right now 18K costs ₹9,387.23 (AED 366.53) a gram in Dubai, against ₹11,465.06 (AED 447.66) for 22K. The table below shows 18K prices for common weights, so you can see what a 5 g ring or a 20 g bracelet costs in gold before making charges.

The 18K rate page carries the full daily picture if you want to follow it over time.

Worked example with a 6 g ring

Say Rohan is buying a ring with a small diamond. The gold part weighs 6 g. He is offered the same design in 22K or 18K. Illustrative figures: 22K at AED 295 a gram, 18K at AED 242 a gram, making at AED 60 a gram (a fine setting costs more to make), and the diamond at AED 1,800.

The 22K version

• Gold: 6 × 295 = AED 1,770
• Making: 6 × 60 = AED 360
• Diamond: AED 1,800
• Subtotal: AED 3,930; with 5% VAT, AED 4,126.50

The 18K version

• Gold: 6 × 242 = AED 1,452
• Making: AED 360
• Diamond: AED 1,800
• Subtotal: AED 3,612; with 5% VAT, AED 3,792.60

The 18K ring costs about AED 334 less. More important, the stone is held more safely, and a lost diamond would cost far more than the gold difference. In this case 18K is clearly the better buy.

Now picture a plain 6 g band with no stone. The 22K version gives Rohan about 5.5 g of pure gold; the 18K version about 4.5 g. If he ever sells it, the 22K band returns more. For a plain band he may value that more than scratch resistance. Neither answer is wrong; it depends on whether the piece is mainly jewellery or mainly a store of gold.

What happens when you sell 18K in India?

Indian jewellers buy 18K, test it, and pay for the gold content at the day's rate minus their deduction. With diamond pieces, the stones are valued separately, and many jewellers pay little for small diamonds on resale. Expect the gold part to be your main return.

Because 18K jewellery often carries higher making charges and stones, the gap between what you paid and what you get back tends to be wider than with plain 22K. That is normal. You bought a design, not just metal. If resale value is your priority, buy plain 22K or look at bars and coins instead.

To see how the 22K rate has moved over the past year, which shapes what plain gold jewellery is worth when you sell, here is the live chart.

Daily wear, skin and care

Some people find that lower-karat alloys mark their skin or cause irritation, often because of specific alloy metals such as nickel in some white gold. If you have sensitive skin, ask the jeweller what the alloy contains. 22K, with less alloy, is less likely to react, though reactions vary from person to person.

Care is simple for both. 18K white gold may need re-plating every so often to stay bright. 22K needs gentle cleaning and careful storage so softer pieces don't scratch against each other.

Mistakes people make with this choice

• Comparing gram rates only. An 18K piece with a high making charge can cost more than a plain 22K piece of the same weight. Look at the full bill.
• Paying gold rate on stone weight. If the invoice shows one gross weight for a diamond ring, you may be paying the 18K rate on the diamond too. Ask for gold and stone weights separately.
• Assuming 18K is "low quality". It is a different alloy for a different job, not a cheaper version of 22K.
• Buying 22K diamond pieces for the gold value. The stones and settings limit what you get back, and the softer metal puts the stones at more risk.

Quick decision list

• Stones involved? Go 18K.
• White or rose colour wanted? Go 18K.
• Plain gold, Indian design, may sell or exchange later? Go 22K.
• Thin pieces worn every day? 18K resists damage; 22K keeps more value. Pick based on which matters more to you.
• Buying mainly to save? Neither. Compare 24K and 22K instead.

Whichever you choose, check the stamp, ask for the stone weight to be deducted from the gold weight, and keep the itemised invoice.
