Hallmarking is the process of verifying and certifying the purity of gold in karats and fineness as per the standards set by the BIS (Bureau of Indian Standards). Every hallmarked gold item has 4 symbols on it – BIS mark, Purity in karat and fineness (e.g. 22k916), Assaying and Hallmarking Centre’s mark and Jeweller’s mark.

Hallmarked gold consists of four symbols that prove that a gold article has undergone the process of hallmarking as per the processes set by the BIS (Bureau of Indian Standards). These include:

BIS (Bureau of Indian Standards) logo
Purity in karat and fineness
Assaying and Hallmarking Centre’s identification mark
Jeweller’s identification mark

Hallmarking in India is monitored by the BIS (Bureau of Indian Standards), the national standards organization of India. The BIS is the only entity that can authorize Assaying and Hallmarking Centres (AHCs) to hallmark gold and license jewellers to sell hallmarked gold.

Hallmarking ensures that the gold jewellery you purchase is worth the money you pay. It assures you of the purity and fineness of your gold. It is also easy to sell hallmarked gold as the buyer will offer you the right value. A hallmark also assures you that your gold has been ethically sourced.

You can also check if a jeweller is licensed by the BIS by asking for a BIS certificate at their store and by confirming that the jeweller’s mark matches the one mentioned in this list.

How much does it cost to get gold hallmarked?
The hallmarking charge is INR 35 per gold article. This cost is born by the jeweller, not you, as the buyer. This cost applies regardless of the size, weight or purity of your gold piece. However, the piece must be minimum 2 grams for you to get it hallmarked.

White gold is not a naturally white metal. It is yellow gold alloyed with other metals to achieve a white look. The white colour is often further enhanced by plating the piece with rhodium. This plating could wear away, revealing the yellow-grey colour underneath. Platinum on the other hand is a naturally white precious metal which never fades or loses colour even after years of wear. Platinum jewellery is 95% pure platinum compared to 18k gold / white gold jewellery which is 75% pure gold. You can tell the difference between platinum and white gold by their weight. Platinum is a dense metal, 40% more dense than gold. Even a simple platinum wedding band is noticeably and reassuringly heavier than the same ring made of white gold.

Every piece of platinum jewellery, however small, carries the ‘Pt 950’ mark. It is a symbol of authenticity and signifies 95% purity (950 parts out of 1000). Also, every piece of platinum jewellery has a unique identification number. The Purity Assurance Card that comes with your purchase of platinum jewellery carries this identification number along with the weight and purity of the piece. To be rest assured of platinum jewellery’s authenticity, make sure you purchase it from a PGI authorised retailer. Ensure that your platinum piece carries the Pt 950 mark. Insist on the Purity Assurance Card with every purchase of platinum jewellery.
