What is Gold Hallmarking?
Gold hallmarking is the process of certifying the purity and fineness of gold by an authorized agency. In India, the Bureau of Indian Standards (BIS) is the official body responsible for hallmarking gold under the guidelines of the Government of India.
A BIS hallmark ensures that the gold you are buying or selling meets the exact standards of purity. This is especially important if you are planning to sell your gold to a reputed refinery like Rahul Refinery, known for being the best old gold buyer in Kolkata.
Why is Gold Hallmarking Important?
- Guarantees Purity: Hallmarked gold assures you that you’re getting what you paid for.
- Higher Resale Value: Hallmarked gold has better resale value, especially when selling to the best old gold buyer in Kolkata.
- Prevents Fraud: It helps customers avoid being duped by jewelers who may offer lower-purity gold at higher prices.
- Transparency: Promotes transparency between buyers and sellers in the gold market.
How To Check if Your Gold is Hallmarked
To check if your gold is hallmarked, look for the following signs on your gold jewelry:
- BIS Logo – The official symbol of the Bureau of Indian Standards.
- Purity Grade – Such as 22K916 (91.6% pure), 18K750, etc.
- Assaying Centre’s Mark – Identification of the BIS-recognized testing center.
- Jeweler’s Identification Mark – Unique code given to BIS-certified jewelers.

If you’re unsure how to read these, bring your gold to Rahul Refinery, the best old gold buyer in Kolkata, where our experts will verify it for you.
How does the hallmarking process ensure the purity of gold?
The hallmarking process ensures the purity of gold through a series of standardized, government-regulated steps designed to accurately determine and certify the gold content in jewellery and artefacts.
How the Hallmarking Process Works
- Scientific Testing of Purity:
Gold items are first tested for their purity using advanced methods such as fire assay (considered the most accurate) and X-ray fluorescence (XRF). These tests determine the exact proportion of gold in the item, distinguishing it from other metals that may be mixed in during manufacturing.
- Certification at Authorized Centers:
The testing is carried out at BIS-approved assaying and hallmarking centers, which are specifically authorized to assess gold purity as per Bureau of Indian Standards (BIS) norms. Only gold that meets the prescribed standards is certified.
- Imprinting the Hallmark:
Once purity is verified, the gold item is stamped with a hallmark that includes:
- The BIS logo, certifying government approval
- The purity mark (in karat and fineness, e.g., 22K or 916)
- The mark of the assaying and hallmarking center
- A unique six-digit Hallmark Unique Identification Number (HUID), mandatory since April 2023
- Consumer Verification:
These marks provide transparency and allow consumers to verify the authenticity and purity of their gold using the BIS Care App or by checking the HUID number.
Why Hallmarking Guarantees Purity
- Standardization:
The process follows strict national standards, ensuring that only gold of certified purity is sold. - Protection Against Adulteration:
By certifying the actual gold content, hallmarking protects consumers from fraud and adulteration, offering peace of mind and better resale value. - Legal Compliance:
In India, hallmarking is mandatory for gold jewellery, making it a legal guarantee of purity and authenticity

In homogeneity testing, the entire batch or parcel of gold jewellery is tested to confirm consistent purity throughout the items. This step may involve withdrawing samples or selecting representative pieces for detailed analysis.
- Purity Testing / Assaying
The sampled gold undergoes precise testing to determine its actual purity. Common methods include:
- Fire Assay (Cupellation): A chemical refining process that separates pure gold from other metals to calculate gold content, considered the most accurate method.
- X-Ray Fluorescence (XRF): A non-destructive technique that analyzes the metal composition quickly and accurately.
The purity is expressed in karats (e.g., 14K, 18K, 22K) or fineness (parts per thousand, e.g., 916 for 22K).
- Marking / Stamping the Hallmark
After confirming purity, the jewellery is stamped with the official hallmark, which includes:
- The BIS logo certifies government approval
- The purity mark indicating karat and fineness
- The assaying and hallmarking centre’s mark
- A unique Hallmark Unique Identification Number (HUID) — a six-digit alphanumeric code introduced recently for traceability
- Marking can be done by:
- Hand marking: Traditional punch and hammer method
- Press marking: Using a fly press or air press
- Laser marking: Modern, precise, and durable engraving, often used for the HUID and BIS logo
