Hallmarking is a certification by the Bureau of Indian Standards (BIS) that the gold is of a particular purity.
Effective from June 16, 2021, the central government has made hallmarking of gold mandatory. This means that any gold jewellery sold by a jeweller in India must have BIS hallmarking to certify the product’s purity.
Further, effective from July 1, 2021, the government has revised the signs of hallmarking on gold jewellery. As per the Department of Consumer Affairs, now BIS hallmark on gold jewellery will consist of three symbols:
a) BIS Standard mark
b) Purity/Fineness Grade and
c) 6-digit alpha-numeric code
Here is a look at what these three symbols denote and how it will help consumers of gold.
Three signs on BIS hallmarked gold jewellery
a) BIS Standard mark
The first sign of hallmark on gold jewellery is the BIS logo. The logo is in the shape of a triangle. The stamp of this logo on gold jewellery shows that the purity of gold jewellery has been checked at a BIS certified centre.
b) Purity/Fineness Grade
The second sign of hallmark on gold jewellery is the sign of purity. This sign tells you the degree of purity of gold in a particular piece of gold jewellery. The purity of gold so determined forms the basis of the price of that piece of gold jewellery.
As per the BIS website FAQs, hallmarking of gold jewellery is permitted in six categories: 14K, 18K, 20K, 22K, 23K and 24K.
The hallmark on gold jewellery will be shown as 22K916, 18K750, 14K585 etc.
|Sign on gold jewellery||Purity of gold|
|22K916||Contains 91.6% gold|
|18K750||Contains 75% gold|
|14K585||Contains 58.5% gold|
- If a gold jewellery piece has 22K916 stamped on it, then it means that the particular piece of gold jewellery has 91.6% gold and the balance (8.4%) is other metals such as zinc etc.
- Similarly, 18K750 gold jewellery means that a particular piece of gold jewellery has 75% gold and rest is other metals.
- 14K585 means that the gold product is 14-carat gold having 58.5% of gold.
c) Six-digit alphanumeric code
The third sign of hallmarked gold jewellery is a six-digit alphanumeric code embossed/ etched on the product. This code – also called Hallmark Unique Identification (HUID) number–is unique for every jewellery piece. Customers can verify this alphanumeric code on the BIS Care App. Customers can download the BIS Care App on their mobile phone. The ‘Verify HUID’ feature can be used on the BIS Care App to verify the alphanumeric code of the jewellery and also to verify the purity of jewellery.
Do note that mentioning of six-digit HUID code is not mandatory on the bill at present.
BIS Hallmarking signs before July 1, 2021
Earlier, the hallmarking of gold jewellery had two other signs apart from BIS logo mark and purity sign. These were: Assay centre’s identification mark/number and Jeweller’s identification number. However, these two signs have been replaced with the alphanumeric HUID code.
If a customer buys gold jewellery that has old-hallmarking signs, then it is not necessary to get it re-hallmarked with the six-digit code.
Charges for BIS hallmarked gold jewellery
A jeweller selling you BIS hallmarked gold jewellery will charge you Rs 35 per piece of gold jewellery for the hallmarking. The hallmarking charges will be added to the cost and mentioned on the bill. The price of hallmarking a jewellery is a flat charge irrespective of the weight of the gold jewellery.
