22K vs 24K Gold: What Is the Difference?
22K and 24K are the two gold purities you'll see most often when checking a gold rate or buying jewellery in India. This guide explains what each one means, why their prices differ, and how the 22K reference rate on this site is worked out from the 24K rate.
What Is 22K Gold?
22K gold is 22 parts pure gold out of 24 — a fineness of about 91.6%. The rest is other metals such as copper, silver or zinc, alloyed in to make the gold stronger. 22K is the purity most commonly used for gold jewellery in India.
What Is 24K Gold?
24K gold is treated as close to pure gold on this site, with a fineness of 99.9%. It's soft in its pure form, so it's mainly used for gold coins, bars and investment-grade gold rather than everyday jewellery.
22K vs 24K: The Key Differences
The core difference is purity: 24K gold contains a higher proportion of pure gold than 22K gold, which is alloyed with other metals for added strength. Because the gold rate is based on how much pure gold a given weight actually contains, 24K gold has a higher reference rate per gram than 22K gold of the same weight. 24K's softness also makes it impractical for jewellery that needs to hold its shape under daily wear, which is why 22K — and lower purities like 18K — are used instead.
What Do "Purity" and "Fineness" Mean?
Purity describes how much of a piece is actually gold, usually expressed in karats (out of 24) for jewellery. Fineness expresses the same thing as a fraction — for example, a fineness of 0.916 means 916 parts per 1000 are pure gold. This site uses the fineness value for each purity to work out its reference rate from the 24K base rate, as shown below.
24K vs 22K at a Glance
A quick side-by-side comparison, based on the purity and fineness definitions used across this site.
| Purity | Fineness | Typical use | Relative reference rate |
|---|---|---|---|
| 24K Gold | 999 fineness | Coins, bars, investment-grade gold | Base reference rate (100%) |
| 22K Gold | 916 fineness | Gold jewellery (most common purity in India) | About 91.7% of the 24K reference rate |
How Is the 22K Gold Rate Calculated From 24K?
On this site, only the 24K gold rate is entered manually — every other purity, including 22K, is derived from it using the fineness ratio between the two purities. In other words: 22K rate = 24K rate × (22K fineness ÷ 24K fineness). This keeps every purity's rate consistent with the 24K base rate automatically, without needing a separately sourced quote for each one.
At today's reference rate, 24K gold is ₹7,350/gram and 22K gold is ₹6,739.34/gram — because 22K's fineness is about 91.7% of 24K's, its reference rate works out to about 91.7% of the 24K rate too.
This is a calculated reference derivation, not an independently sourced or live market quote — see the gold rate page for the exact figures used across every calculator on this site.
Why Does Jewellery Commonly Use Lower Purity Than Pure Gold?
Pure gold is soft, so jewellery made entirely from 24K gold bends and scratches easily and doesn't hold fine detailing well. Alloying gold with other metals — as happens in 22K, 18K and 14K gold — makes it more durable, which is why jewellery, especially pieces meant for daily wear or set with stones, is commonly made in a lower purity than 24K.
Which Purity Is Used for Jewellery?
22K is the most common purity for gold jewellery in India, while 18K is more often used for jewellery set with stones or diamonds due to its added durability. Neither purity is universally "better" — the right choice depends on the type of jewellery, its intended use and personal preference. See the gold rate page for the reference rate of every purity this site supports (24K, 22K, 18K and 14K).
What to Check When Buying Gold Jewellery
The gold rate is only the starting point of a jewellery bill. When buying, it helps to check: the purity marked on the item (and its hallmark, where applicable), the weight used for billing, the making charges and whether they're a flat amount or a percentage, any wastage charge, and GST. Use the gold jewellery calculator below to see how these combine into an estimated purchase price.
Reference Rate vs. Final Jewellery Price
The rates on this page and across this site are manually maintained reference values, not live market quotes, and are not specific to any jeweller. A jewellery shop's final price adds making charges, possible wastage and GST on top of the gold value, and these vary by jeweller, design and state. Nothing here is a guaranteed price — always confirm the final price and an itemised bill with the jeweller before completing a purchase.

- What is the purity of 22K gold?
- 22K gold has a fineness of 0.916, meaning it is about 91.6% pure gold by weight.
- What is the purity of 24K gold?
- 24K gold is treated as 99.9% pure on this site (a fineness of 0.999), the standard reference purity used for bars, coins and investment-grade gold.
- Why is 22K gold cheaper than 24K gold?
- 22K gold contains less pure gold per gram than 24K gold, so its reference rate — based on actual gold content — works out lower than the 24K rate for the same weight.
- How is the 22K gold price calculated on SonaChandiTools?
- 22K isn't priced independently — it's derived from the manually maintained 24K base rate using the fineness ratio between 22K and 24K, so it always stays consistent with the 24K rate shown on the gold rate page.
- Can jewellery price be calculated only from the gold rate?
- No. The gold rate covers only the value of the gold itself. An actual jewellery price also includes making charges, any wastage charge and GST, which vary by jeweller — use the gold jewellery calculator to see a fuller estimate.
