At Zaffiro, we prioritize the authenticity and purity of our gold jewellery, ensuring that every piece meets the highest standards. Here, we provide you with comprehensive information about hallmarking, its importance, and how you can identify genuine hallmarked gold jewellery.

What is Hallmarking?
Hallmarking is the process of certifying the purity of gold or silver jewellery. When a piece of jewellery is hallmarked, it means that it has been tested and certified by an authorized center for its declared purity. In India, the Bureau of Indian Standards (BIS) is the competent authority that licenses these centers. Jewellers selling hallmarked jewellery also require a license from BIS, allowing them to sell only authentic, certified gold or silver articles. Notably, in India, it is mandatory to hallmark gold jewellery with a Hallmark Unique Identification Code (HUID).
Types of Hallmarking in Gold Jewellery
Gold jewellery can come in various purities, and each purity level has a specific hallmark. Here are the different types of hallmarking based on gold purity:
14k (carat): Stamped as 14K585
18k (carat): Stamped as 18K750
20k (carat): Stamped as 20K833
22k (carat): Stamped as 22K916
23k (carat): Stamped as 23K958
24k (carat): Stamped as 24K995

How to Identify Genuine Hallmarked Gold Jewellery
Identifying genuine hallmarked gold jewellery is straightforward. Here’s what you need to look for:
Hallmark Unique Identification Code (HUID): A unique alphanumeric code present on the jewellery.
BIS Triangle Logo: Indicates certification by the Bureau of Indian Standards.
Purity Mark: For example, 22K916 for 22-carat gold or 14K585 for 14-carat gold.
Jeweller's Name or Logo: The name or logo of the jeweller selling the article.
Additional Stamps: Extra stamps such as a number or symbol to identify the supplier or craftsman (karigar).
An authentic hallmarked jewellery piece will have these stamps. Anything else could indicate doubts about the article's purity or fineness. Insist on HUID hallmarking, which costs only 236 INR at most. This HUID provides complete information about the article, including:
Type of article (e.g., bangle, earring, ring)
Weight
Hallmark center name
Date and city of hallmarking
