Hallmarking is your best assurance of purity when buying gold or silver jewelry. But what exactly is a hallmark—and how do you check one? Here’s what you need to know before making your next purchase.

What Is a Hallmark?

A hallmark is an official mark stamped on precious metals to certify its purity, tested and verified by authorized agencies.

In India, BIS (Bureau of Indian Standards) is the official hallmarking authority.

How to Read a BIS Hallmark

A standard BIS hallmark includes:

• BIS Logo

• Purity in Karat and Fineness (e.g., 22K916 means 22 karat, 91.6% pure gold)

• Assaying Centre Mark

• Jeweller’s Identification Mark

• Year of Hallmarking (optional letter code)

Where to Find the Hallmark on the Jewelry

Look for tiny engravings on the inner band of rings, back of pendants, clasp of chains, or bangles. Use a magnifying glass if needed.

How to Verify the Hallmark

You can:

• Ask for the original BIS Certificate

• Check on the BIS Care App (India-specific) by entering the 6-digit HUID (Hallmark Unique Identification)

Avoid Buying Non-Hallmarked Jewelry

While it might be cheaper, non-hallmarked gold carries risks in purity and resale value. Always insist on hallmarked pieces—especially for investment jewelry.

Conclusion
Understanding hallmarking empowers you as a buyer. Whether you’re buying for love, style, or investment—never compromise on authenticity.
