The Hallmark Guarantee: Why You Should Never Buy Non-Hallmarked Gold
What do those tiny stamps on your gold actually mean? We decode the BIS Hallmark and why it is your only protection against fraud.
Gold is synonymous with wealth in India. But unlike a currency note which has a fixed value printed on it, the value of gold depends entirely on its purity.
Many customers are surprised to learn that pure gold (24 Karat) is actually very soft—almost like clay. If you were to make a ring out of 100% pure gold, it would bend out of shape with a simple handshake. To make gold durable enough to be worn as jewelry, it must be mixed with other metals like copper, silver, or zinc to give it strength.
This mixing process is where the “Purity” comes in:
22 Karat (916): Contains 91.6% Gold. This is the standard for weddings and daily wear jewelry.
18 Karat (750): Contains 75% Gold. This is harder and stronger, making it the standard for holding heavy diamonds and gemstones.
The Risk of “Local” Gold
In the past, the jewelry market was unorganized. Unethical jewelers would mix more copper than allowed. They would sell a piece claiming it was “22 Karat,” but in reality, it might have been only 18 or 19 Karat.
The customer would never know the difference—until years later when they tried to exchange or sell the jewelry. They would be shocked to find out their investment was worth 20% less than they thought.

The BIS Hallmark Shield: Your Protection
Today, you no longer have to rely on blind faith. The Bureau of Indian Standards (BIS) has made Hallmarking mandatory. This acts as a third-party guarantee of purity.
When you buy a piece of gold, you must look for the laser-engraved Hallmark, which consists of three distinct parts:
1. The BIS Logo A small triangle-shaped mark that indicates the jewelry has been evaluated in a government-approved assay center.
2. The Purity Grade This tells you exactly how much gold is in the metal.
22K916: For standard gold jewelry.
18K750: For diamond and studded jewelry.
14K585: For lifestyle and lightweight jewelry.
3. The HUID Code (Hallmark Unique Identification) This is the game-changer. It is a unique 6-digit alphanumeric code (e.g., H56 YU3) laser-etched onto the jewelry. Think of HUID as an Aadhar Card for your ring or necklace. By entering this code into the BIS Care App on your phone, you can see:
Who the jeweler is.
Which center tested the gold.
The exact purity of the piece.
