A Complete Buyer’s Guide by Silnoi – Silver Begins Here

When purchasing silver jewellery, authenticity matters. With so many options available in the market, it is important to know whether you are investing in genuine 925 sterling silver or imitation metal.

This guide will help you understand how to identify original silver jewellery and what the BIS hallmark truly means.


What is 925 Sterling Silver?

925 sterling silver contains 92.5% pure silver and 7.5% alloy (usually copper) for added strength and durability. Pure silver (99.9%) is too soft for everyday jewellery, which is why 925 silver is the global standard for quality and longevity.

If a piece is not marked 925, you should verify its authenticity carefully.


What is BIS Hallmark?

BIS stands for the Bureau of Indian Standards, the national body that certifies the purity of precious metals in India.

A BIS hallmark ensures:

  • The silver meets purity standards

  • The jewellery is officially tested

  • You are buying authentic silver

Buying BIS hallmarked jewellery protects you from fraud and guarantees quality.


How to Check if Silver Jewellery is Original

1. Look for the “925” Stamp

Original sterling silver jewellery usually carries a small “925” mark engraved on it. It may be located on:

  • The clasp of a chain

  • Inside a ring band

  • The back of the earrings

  • The hook of a pendant

This indicates 92.5% silver purity.


2. Check for BIS Hallmark Symbol

Authentic silver jewellery in India may also carry:

  • BIS logo

  • Purity mark (925)

  • Jeweller’s identification mark

These markings confirm certified purity.


3. Magnet Test

Silver is not magnetic. If the jewellery strongly sticks to a magnet, it is likely not pure silver.
However, this test is not fully reliable — it should only be used as a basic check.


4. Tarnish Test

Real silver may tarnish slightly over time when exposed to air. Artificial jewellery usually does not tarnish in the same way. Tarnish on silver is normal and can be cleaned.


5. Buy from a Trusted Brand

The safest way to ensure authenticity is to purchase from a reputable brand that clearly mentions:

  • 925 sterling silver

  • BIS hallmark certification

  • Transparent product details


Why BIS Hallmarked Silver Matters

Choosing BIS-certified silver jewellery means:

  • Assured purity

  • Better resale value

  • Long-term durability

  • Protection against counterfeit products

It is not just about style — it is about trust.
