Gold Purity Secrets Revealed
Unhallmarked Gold Seized!
India's BIS recently seized ₹10 crore in unhallmarked gold, highlighting the need for purity verification.
This underscores the importance of HUID hallmarking for consumer protection and fair value
Why Gold Purity Matters
When you buy gold, you're paying for pure gold content, not just total weight.
Knowing purity ensures you get the real value for your hard-earned money.
What are Karats?
Karats (K) measure gold purity. 24K is 99.9% pure gold, 18K is 75% pure.
It tells you how much actual gold is present in your jewellery or coin.
Purity & Your Gold's Value
The higher the karat, the more pure gold it contains, and the higher its market value.
A small difference in purity can mean a big difference in cost, like comparing petrol at ₹105/litre.
How is gold purity calculated?
Purity is calculated as (Karat / 24) * 100%. 24K is the highest purity.
For example, 22K gold means (22/24) * 100% pure gold.
What is the purity percentage of 22K gold?
22K gold has a purity of 91.6%. It's common for jewellery due to its durability.
The remaining 8.4% is usually copper or silver, added for strength.
How many grams are in one tola of gold?
One tola equals exactly 11.6638 grams. It's a traditional unit in India.
Many local jewellers still quote prices per tola, not just per 10 grams.
11.6638 g
The exact weight of one tola – not 10 grams. This is crucial for value
Let's Calculate!
Imagine you're buying a beautiful 20-gram necklace of 22K gold.
The current market rate for 24K gold is ₹7,200 per gram.
Step 1: Find Pure Gold Content
For 22K gold, the purity is 91.6% (or 0.916).
This means 91.6% of your 20-gram necklace is pure gold.
Step 2: Calculate Pure Gold Weight
Total weight (20g) x Purity (0.916) = 18.32 grams of pure gold.
So, your 20-gram necklace contains 18.32 grams of actual 24K gold.
Step 3: Determine Real Value
Pure gold weight (18.32g) x Rate (₹7,200/g) = ₹1,31,904.
This is the raw gold value, before making charges and GST.
How to find pure gold content by weight?
Multiply the total weight of the item by its purity percentage (Karat/24).
For example, 50 grams of 18K gold has 50 * (18/24) = 37.5 grams of pure gold.
What is the purity of 24K gold?
24K gold is considered 99.9% pure gold, the highest standard.
It's too soft for jewellery, often used for coins, bars, and investments.
How to convert gold karats to purity percentage?
Divide the karat number by 24 and multiply by 100. (Karat / 24) x 100%.
Example: 14K gold is (14/24) * 100% = 58.3% pure.
Always Verify HUID
Mandatory HUID (Hallmarking Unique Identification) ensures gold purity.
Scan the HUID to check details and prevent fraudulent purchases.
Factor in Making Charges & GST
Jewellery prices include making charges (design cost) and applicable GST.
These add to the final price but aren't part of the gold's intrinsic value.
Gold Rates Fluctuate Daily
Gold prices change constantly based on market demand, global events, and currency.
Check live rates before buying or selling to get the best deal.
Tola vs. 10 Grams
A 10-gram gold rate understates a tola's price by about 16.6%.
At ₹7,200/gram, one tola costs ₹83,979, not ₹72,000!
What About Older Gold?
Old jewellery might not have HUID. Purity can be estimated or tested by a jeweller.
Reselling older gold might require a re-hallmarking or a purity assessment.
