The Bureau of Indian Standards (BIS) Hallmarking is an official certification system introduced by the Government of India to ensure the purity and fineness of gold and silver jewellery. This mark serves as a trust symbol for both jewellers and consumers, guaranteeing that the precious metal used in the jewellery has been tested and verified in an BIS-approved laboratory.
BIS Hallmarking not only confirms the authenticity of metal purity (like 22K, 18K or 14K for gold), but also helps in preventing fraud and building confidence in the jewellery market. Every hallmarked item carries four distinct marks — the BIS logo, purity grade, jeweller’s identification, and the testing centre’s mark — together representing quality, transparency, and trust.
By implementing hallmarking, the Indian government aims to protect consumers from low-purity or adulterated jewellery and to promote standardization across the industry. Today, BIS Hallmarking has become a symbol of integrity and assurance, ensuring that every customer gets exactly what they are paying for — pure, certified, and genuine gold or silver.

BIS Hallmark is a certification mark given by the Bureau of Indian Standards to confirm the purity of precious metals. When jewellery carries a BIS hallmark, it guarantees that the item has undergone rigorous testing in an authorized lab. The hallmark acts as a symbol of authenticity, protecting customers from fake or low-purity metals. Every hallmarked piece includes marks that indicate the metal’s purity, testing centre, and the jeweller’s identity. Simply put, it is the government’s guarantee that your jewellery is genuine.

Purpose of BIS Hallmark

The purpose of BIS Hallmark is to ensure that customers receive pure and genuine gold or silver jewellery as promised by the seller. It helps in building trust between jewellers and buyers by verifying the metal’s quality through authorized testing centres. This certification also protects consumers from adulteration or fraud, promoting transparency in the jewellery trade. By maintaining uniform purity standards, BIS hallmarking strengthens the credibility of Indian jewellery in both domestic and international markets. In short, its main aim is to safeguard consumers and standardize purity across the industry.

A typical BIS Hallmark consists of four main parts:

1. BIS Logo – Represents the Bureau of Indian Standards.
2. Purity/Fineness Grade – Shows the exact karat or fineness of gold or silver, e.g., 22K (916), 18K (750).
3. Assaying and Hallmarking Centre’s Mark – Indicates the authorized lab where testing was done.
4. Jeweller’s Identification Mark – Identifies the registered jeweller who sold or manufactured the piece.

These marks together provide complete transparency, trust, and legal assurance to the buyer

1. Booking or Submission – Customers can schedule a pickup or visit the lab to submit jewellery.
2. Initial Inspection – Jewellery is weighed and visually examined for authenticity.
3. Testing – Gold and silver are tested using approved techniques like fire assay or spectrometry to determine purity
4. Hallmarking – Certified pieces receive the official BIS mark at a specific location.
5. Certification – A BIS hallmark certificate is issued, along with a detailed test report.
Return or Delivery – Jewellery and certificates are returned to the customer securely.
