22 Carat Gold Purity: Meaning, Uses and Value

• The purity of 22-carat gold is 91.67%, meaning 22 out of 24 parts are pure gold.

• It is the most preferred gold for jewellery due to its ideal balance of purity and durability.

• While great for jewellery, 24-carat gold remains the better option for pure investment purposes.

When buying gold jewellery, understanding the purity of 22-carat gold can help you make a much smarter decision. Gold is one of the most trusted assets in India. It is not only passed down through generations and gifted at weddings but also has great cultural significance. But not all gold is the same, and knowing what you're actually buying matters more than most people realise. Whether you're shopping for a necklace or planning a long-term investment, here is everything you need to know about 22-carat purity and what it means for you.

The carat (or karat) system is the standard way to measure gold purity in 22-carat and other grades. Pure gold is rated at 24 carats, meaning it is 100% gold with no other metals mixed in. So when we talk about 22-carat gold purity, we are referring to gold that contains 22 parts of pure gold out of a total of 24 parts. The remaining two parts are made up of other metals like silver, zinc, or copper.

These added metals are not a flaw; they are intentional. Pure 24-carat gold is extremely soft, making it impractical for everyday jewellery. By mixing in small amounts of other metals, jewellers create an alloy that holds its shape, resists scratches, and lasts for decades. This is precisely why 22 kt gold purity has remained the gold standard (quite literally) for crafting jewellery in India and around the world.

The 22-carat purity percentage is calculated as a simple fraction: 22 ÷ 24 × 100. Here is a quick breakdown of what that looks like across different gold carats:

Here’s why 22k gold purity dominates the jewellery market in India. Here is what makes it different:

1. High Purity

At 91.67%, 22-carat gold purity is very close to pure. The small percentage of added metals gives it just enough hardness to be crafted into intricate designs without losing its rich colour or value.

2. Rich Colour

The high gold content gives it a deep, warm yellow tone that most buyers associate with premium jewellery. Lower-carat gold often appears paler or more rose-tinted due to higher copper content.

3. Easily Accepted and Resold

In India, 22-carat gold is the most commonly traded form of jewellery gold. It is accepted by jewellers nationwide, making it easy to sell or exchange when needed.

4. BIS Hallmark Verification

All 22 ct gold jewellery sold in India is required to carry a BIS (Bureau of Indian Standards) hallmark. This stamp guarantees that the gold meets the declared purity standard and protects buyers from fraud.

Understanding the difference between 22 carat purity and 24 carat gold helps you choose the right form for your needs:

Here’s how you can verify the purity of 22-karat gold:

1. Look for the BIS hallmark.

Always check for the BIS hallmark on the jewellery. For the 22-carat gold, the stamp should read '916', which represents 91.6% purity.

2. Buy from a trusted source

Buy from certified or renowned jewellers who provide proper bills and purity certificates.

3. Ask for a certificate

For larger purchases, you can ask for an independent assay (purity test). Some hallmarking centres and labs also offer XRF (X-ray fluorescence) testing, which provides a precise reading of the 22-carat purity percentage without damaging the piece.

Understanding 22-carat gold purity is the first step towards making informed decisions, whether you are buying jewellery for a wedding, gifting a loved one, or simply adding to your savings. 22-carat gold is primarily a jewellery-grade metal. However, from a pure investment perspective, 24-carat gold coins or bars offer better returns due to their higher purity.

If you are looking to invest in gold as a financial asset, Aditya Birla Capital offers access to digital gold, gold ETFs and more, which let you benefit from gold's price movements without worrying about making charges or storage. That said, 22-carat purity gold jewellery holds its value well and remains a meaningful hedge against inflation, especially in the Indian market.
