What Is Hallmark Gold? How to Identify Genuine Gold
Buying gold is a major financial decision, and ensuring its purity is extremely important. Many buyers unknowingly purchase non-hallmarked or under-purity gold, which can lead to losses during resale or exchange.
In this guide, we explain what hallmark gold is, why it matters, and how to identify genuine gold before making a purchase.
🏷 What Is Hallmark Gold?
- Certification: Hallmark gold is gold that has been certified for its purity by an authorized agency.
- Quality Assurance: It guarantees that the metal used confirms to the international standards of purity.
- Buyer Protection: It protects buyers from adulteration and ensures they get the gold quality they pay for (e.g., if you pay for 22K, you get 22K).
🏛 What Is BIS Hallmark in India?
In India, the Bureau of Indian Standards (BIS) is the government body responsible for certifying gold.
- Mandatory: The government has made hallmarking mandatory in many districts to curb fraud.
- Trust: Buying BIS-hallmarked gold means you are buying a product backed by a reliable third-party guarantee.
🔍 BIS Hallmark Components Explained
A genuine BIS hallmark consists of three major components (since the new HUID system):
- BIS Logo: The standard triangular mark.
- Purity Grade: Indicates the fineness (e.g., 22K916 for 22 Karat, 18K750 for 18 Karat).
- 6-Digit HUID Code: A unique Alphanumeric code that allows you to trace the jewellery back to the jeweller and assay centre using the BIS Care App.
🧪 Common Gold Purity Levels in India
- 24K (999): 99.9% pure gold. Primarily for bullion/investment.
- 22K (916): 91.6% pure gold. The standard for wedding jewellery.
- 18K (750): 75.0% pure. Used for diamond/stone-studded and trendy daily wear jewellery.

🪙 How to Identify Genuine Gold Before Buying
- Check BIS Hallmark Symbols: Use a magnifying glass to spot the triangular logo and HUID code.
- Ask for Purity Certificate: Reputed jewellers provide cards certifying the diamond/gold quality.
- Verify Invoice Details: Ensure the bill mentions 'Hallmark charges' and the specific HUID code of the item.
- Avoid Unusually Low Prices: If a deal looks too good to be true (way below market rate), it's likely fake or stolen.
- Buy from Trusted Jewellers: Stick to established names with a long manufacturing history.
🧾 How to Check Gold Purity at Home (Basic Methods)
- Hallmark Inspection: The most reliable method is visual inspection of the laser markings.
- Magnet Test: Pure gold is not magnetic. If your chain sticks to a magnet, it has high iron/nickel content (fake).
- Weight Consistency: Gold is dense. If a large piece feels unusually light, it may be hollow or plated.
- Note: For 100% accuracy, always visit an Assaying Centre.
⚠ Risks of Buying Non-Hallmarked Gold
- Lower Resale Value: Jewellers will deduct 10-20% extra as "wastage" or "melting loss" if there is no stamp.
- Purity Mismatch: You might pay for 22K but receive only 20K or 18K purity.
- No Legal Protection: Without a hallmark/bill, you cannot complain to consumer courts about purity fraud.
