What is 925 Sterling Silver?
925 sterling silver is an alloy containing 92.5% pure silver and 7.5% other metals (typically copper). This composition has been the international standard for quality silver jewelry for centuries.
Why 92.5% and Not 100%?
Pure silver (99.9%) is too soft for jewelry making. The 7.5% copper adds:
- Durability: Stronger and more resistant to scratches
- Shape retention: Holds intricate designs better
- Workability: Easier to craft into jewelry
Understanding BIS Hallmark
The Bureau of Indian Standards (BIS) hallmark is the official purity certification in India. A complete BIS hallmark includes:
1. BIS Logo
The official Bureau of Indian Standards mark indicating the item has been tested.
2. Purity Grade (925)
The three-digit number indicating 92.5% silver content for sterling silver.
3. Assaying Centre Code
A unique code identifying the testing center that verified the purity.
4. Jeweler ID
A unique identification mark of the registered jeweler/manufacturer.
How to Verify Authentic Silver
Look for the 925 Stamp
All genuine sterling silver will have a "925" stamp somewhere on the piece. This may be small, so use a magnifying glass if needed.
Check the BIS Hallmark
Authentic Indian silver jewelry will have the BIS hallmark with all four components. You can verify the hallmark on the BIS website.
Magnet Test
Silver is not magnetic. If your jewelry sticks to a magnet, it's not genuine silver. Note: This test alone isn't conclusive as some fake metals are also non-magnetic.
Ice Test
Silver has the highest thermal conductivity of any metal. Place an ice cube on silver - it should melt faster than on other surfaces due to rapid heat transfer.
