The Government of India introduced a purity system to ensure that consumers do not get duped when buying gold. This marking system is most commonly known as the BIS hallmark, it is devised in a manner to test the purity of gold and certify the product. In the early months of 2021, the Government made it mandatory for every jeweler to follow and abide by the Hallmark regulations.

What Is BIS Hallmarking?

The system which determines the fineness of the silver and gold jewelry sold across the nation is called the Bureau of Indian Standard Hallmarking. In simple words, if a commodity in gold is hallmarked, the consumer can understand the authenticity of the gold. Gold is a fragile metal and is very prone to chipping and breaking, during the process of manufacturing, the jewelers add other metals to the gold to strengthen the gold commodity; metals like zinc and silver are generally used to ensure the strengthening of the gold commodity. The purity system through which hallmarking is commenced is based on the additional metals which are added to the commodity. 

The test process through which the precious metals are assessed is called ‘assaying’ and hence the office which assesses the purity of gold is called the ‘assay office’. According to the Bureau of Indian Standards, hallmarking of gold is conducted to protect the consumers who indulge in buying or investing in gold and to protect against contamination; for safeguarding the consumer’s interest and to help Jewelry manufacturers comply with the regulations, several government-authorized assay offices carry out the purity test to issue purity certifications. 

Why Is It Important To Buy Hallmarked Gold?

By looking at the rare and expensive metal, gold, it is very difficult to determine the purity of gold. Without a confirmation of purity and fineness, a buyer could end up paying more than the actual worth of gold thus being duped and cheated. After checking for all four stamps, one can be sure of the purity and fineness of the piece of gold. 

For jewelers and con artists alike, selling recycled and refurbished gold is easier since they don’t have to merge strengthening metals into the gold commodity again, however, it does affect the purity of gold, and since it is virtually impossible to assess the purity of gold, they jewelers and con-artists have a significant advantage against a buyer who is not aware of the Hallmarking stamps. After identifying the above-mentioned stamps, one can assess the quality, purity, and fineness of the gold by understanding what each sticker stands for thus, avoiding being duped and cheated. 

What Are The Signs Or Stickers Of BIS Hallmark?

The gold jewelry is stamped with four components to ensure the purity of gold. The symbol of Hallmark on the gold which you might have noticed is the symbol of purity according to the Bureau of Indian Standards. 

  • BIS Standard logo

The triangle-shaped stamp indicates the purity of the gold item and is verified in the government-authorized assay office. The triangular stamp could be found on almost every piece of gold jewelry and is very common. 

  • Purity mark

A purity Mark is a stamp that indicates purity in two forms, fineness number, and purity. The carat form has three denominations, 18K, 22k, and 24k. the purest form of gold is rated as 24k and denotes that, 24-carat gold-rated commodities have the least amount of strengthening metals infused in the gold thus, making it closer to, if not, the purest form of gold.

The fineness form of the purity system indicates the purity of the gold through an article that provides information on what percentage of pure gold is in the entire gold alloy. 

  • Assaying and Hallmarking Centre’s Marks

This stamp; on any hallmarked piece of gold indicates the logo of the government-authorized center from which the test of purity was conducted upon the gold commodity. Only licensed assay labs have the authorization to conduct the test of purity on the gold piece. The logo of the assay office is stamped on the gold commodity to ensure that the gold could be traced to protect the owner against any discrepancy. 

  • Jeweler’s Identification Mark

Every Bureau-certified jeweler has a logo, which is unique to every authorized gold commodity seller. The official website of the Bureau of the Indian Standard has a complete list of jewelers, which are certified by them. The jeweler’s Identification Mark is stamped on the piece of gold to protect the owner’s interest and to trace the gold in respect of future discrepancies if there are any.
