How to Check Gold Chain Hallmark Number and Purity in India
**Gold** is one of the most trusted investments and cherished possessions in India. Whether you are buying a gold chain for daily wear, gifting, or investment purposes, checking its hallmark number and purity is essential. A hallmarked gold chain assures buyers that the gold meets specific purity standards and has been certified by an authorized agency.
This comprehensive question-and-answer guide explains everything you need to know about checking a gold chain’s hallmark number and purity in India.
What Is a Hallmark on a Gold Chain?
A hallmark is an official mark stamped on a gold chain that certifies its purity and authenticity. In India, hallmarks are issued under the BIS (Bureau of Indian Standards) Hallmarking Scheme.
The hallmark indicates that the gold has been tested and verified by a BIS-recognized Assaying and Hallmarking Centre.
Why Is Hallmarking Important When Buying a Gold Chain?
Hallmarking protects buyers from purchasing gold with lower purity than claimed.
Benefits of Hallmarking:
- Ensures gold purity and quality
- Provides transparency in gold purchases
- Increases resale value
- Reduces the risk of fraud
- Helps buyers make informed decisions
- Builds trust between customers and jewelers
A hallmarked gold chain gives you confidence that you are paying for genuine gold.
What Information Is Present on a Gold Chain Hallmark?
A BIS hallmarked gold chain generally contains:
1. BIS Logo
The BIS triangle logo confirms that the gold article is certified under BIS standards.
2. Purity or Fineness Mark
This indicates the percentage of pure gold present in the jewelry.
Examples:
Gold PurityHallmark Number24K99923K95822K91621K87518K75014K585
3. HUID Number
A six-digit alphanumeric Hallmark Unique Identification (HUID) code assigned to each jewelry piece.
Where Can I Find the Hallmark on a Gold Chain?
The hallmark is usually engraved in small areas of the chain.
Common locations include:
- Near the clasp
- On the hook section
- On a connecting ring
- On a small metal plate attached to the chain
For very thin chains, the hallmark may be extremely small and require a magnifying glass to view clearly.
What Is the HUID Number?
HUID stands for Hallmark Unique Identification Number.
Each piece of gold hallmarked in India has its own alphanumeric code.
Purpose of HUID:
- Provides traceability
- Prevents counterfeit hallmarking
- Helps verify authenticity
- Makes gold purchases more transparent
No two hallmarked jewelry items have the same HUID.
How Can I Check the Hallmark Number on a Gold Chain?
Follow these simple steps:
Step 1: Locate the Hallmark
Inspect the clasp or connecting links carefully.
Step 2: Identify the BIS Logo
Look for the BIS certification mark.
Step 3: Check the Purity Mark
Find the purity number such as:
- 916
- 750
- 585
Step 4: Note the HUID Code
Write down the unique alphanumeric code.
Step 5: Verify Through BIS
Use the BIS Care App or BIS website to verify the HUID.
How Do I Verify a Gold Chain Using the BIS Care App?
The BIS Care App is one of the easiest ways to verify hallmarked jewelry.
Process:
- Download the BIS Care App.
- Open the Hallmark Verification section.
- Enter the HUID number.
- Submit the details.
- Check the displayed information.
The app will show:
- Gold purity
- Jewelry type
- Hallmark details
- Verification status
What Does 916 Mean on a Gold Chain?
The number 916 indicates that the gold chain contains 91.6% pure gold.
This corresponds to:
22 Karat Gold
The remaining 8.4% consists of alloy metals added for strength and durability.
22K gold is the most popular choice for gold chains in India.
What Does 750 Mean on a Gold Chain?
The hallmark number 750 represents:
18 Karat Gold
This means:
- 75% pure gold
- 25% alloy metals
18K gold is commonly used in designer jewelry because it is stronger and more durable than 22K gold.
What Does 585 Mean on a Gold Chain?
The hallmark number 585 indicates:
14 Karat Gold
Composition:
- 58.5% pure gold
- 41.5% alloy metals
14K gold chains are popular for daily wear due to their durability and affordability.
How Can I Check the Purity of a Gold Chain at Home?
While professional testing is most accurate, you can perform basic checks:
Visual Inspection
Look for:
- BIS logo
- Purity mark
- HUID code
Magnet Test
Gold is not magnetic.
If the chain strongly sticks to a magnet, it may contain other metals.
Color Consistency
Genuine gold generally has a uniform color throughout the chain.
Weight Check
Pure gold chains feel heavier than imitation jewelry of the same size.
These methods provide clues but should not replace professional verification.
Can Hallmarked Gold Be Fake?
Although rare, counterfeit hallmarks can exist.
Warning signs include:
- Missing BIS logo
- Poorly engraved hallmark
- Invalid HUID number
- Extremely low prices
- Purchase from unauthorized sellers
Always verify the HUID before making a purchase.
Is BIS Hallmark Mandatory in India?
Yes. The Government of India has made BIS hallmarking mandatory for most gold jewelry sold in the country.
This regulation protects consumers and ensures standardized quality across the jewelry market.
Which Gold Purity Is Best for Gold Chains?
The ideal purity depends on your purpose.
24K Gold (999)
- Highest purity
- Too soft for chains
22K Gold (916)
- Excellent purity
- Traditional jewelry choice
- Most popular for gold chains
18K Gold (750)

- What is the purity level?
- Can you show the HUID number?
