Gold has long been a symbol of wealth, investment, and celebration. But with rising gold prices, verifying the purity of gold, whether it's jewellery, coins, bars, or bullion, is more important than ever. Whether you’re buying gold for an occasion or investing in a future asset, knowing how to check gold purity at home or while buying protects you from fraud and ensures the right value for your money.
Let’s dive deep into all the reliable methods you can use to verify gold’s purity and discover why AYAANI’s lab grown diamond jewellery might just be the smartest alternative today.
Gold purity is measured in karats (K). Pure gold is 24K, meaning 99.9% gold with minimal impurities. But pure gold is soft and impractical for daily wear, so it's alloyed with other metals like silver or copper.
Karat | Purity (%) | Common Usage |
|---|---|---|
24K | 99.9% | Coins, Bars |
22K | 91.6% | Jewellery |
18K | 75% | Studded Jewellery |
14K | 58.3% | Budget Jewellery |
BIS (Bureau of Indian Standards) is the only authority in India that certifies gold purity. A BIS Hallmarked gold item has:
For example, "22K916" means the gold is 91.6% pure, i.e., 22 karat. Always cross-check all four symbols on the jewellery or document.
Gold is non-magnetic. If your gold item is attracted to a magnet, it's likely impure or fake.
Drop the item in a glass of water. Real gold sinks due to its density. Fakes may float or displace oddly.
Put a drop of vinegar on the gold. Real gold will not react. Be cautious, as this can damage your item.
DIY testing kits with acids and a touchstone are available online and offer decent accuracy for home use.
Jewellers often have machines that provide instant gold purity readings using X-Ray Fluorescence (XRF) technology.
Always ask for a copy of the BIS certification and match it with the jewellery markings.
Coins from the Indian Government Mint or sovereign mints abroad (e.g., Royal Canadian Mint) come with guaranteed purity.
Ensure private mint bars are LBMA-accredited (London Bullion Market Association) or verified by BIS.
Gold-plated items have a very thin layer of gold over base metals. Over time, discolouration, flaking, or greenish tints appear.

Available on Android and iOS, this app allows users to verify jewellers, hallmark numbers, and lodge complaints.

24K | Highest | Investment |
22K | Slightly Lower | Jewellery |
18K/14K | Economical | Daily Wear |
Making charges, stone weight, and taxes affect the final price.

3. What is the most accurate method to check gold purity?
Using a BIS-certified karatmeter or XRF machine gives the most accurate results.
4. How can you identify fake gold?
Fake gold often shows discolouration, reacts to vinegar, or is magnetic.
5. Does AYAANI offer gold jewellery too?
AYAANI specialises in lab grown diamond jewellery, a modern and ethical alternative to traditional gold.
