Understanding BIS Hallmark

Your guide to authentic silver jewelry in India

Expert authentication, guaranteed purity, complete transparency. Everything you need to know about BIS hallmarking for 925 sterling silver jewelry.

What is BIS Hallmark?

The Definition

BIS Hallmark is a certification mark issued by the Bureau of Indian Standards (BIS), the national standards body of India. It verifies the purity and authenticity of precious metal jewelry—gold, silver, and platinum.

Think of it as a "purity guarantee" engraved on your jewelry. When you see a BIS hallmark, it means:

  • ✅ The jewelry has been tested by an official laboratory
  • ✅ The purity grade matches the claim
  • ✅ The jeweler is registered with BIS
  • ✅ You're buying from a legitimate, verified source

Why It Matters

India's silver jewelry market is worth thousands of crores annually. Without hallmarking, buyers often face fraud. BIS hallmarking solves this by creating a transparent, regulated market where both buyers and jewelers are protected.
