BIS Hallmarking Information
What is BIS?
The Bureau of Indian Standards (BIS) is India's National Standards Body established under the BIS Act, 2016.
BIS develops standards and certification systems to promote quality, safety, and consumer confidence across a wide range of products and industries.
What is Hallmarking?
Hallmarking is an independent quality assurance process through which precious metal articles are tested and marked to verify their purity.
A hallmark indicates that the jewellery has undergone testing by an authorized hallmarking centre and conforms to the declared purity standard.
What Does 925 Sterling Silver Mean?
925 Sterling Silver contains:
-
92.5% pure silver.
-
7.5% approved alloying metals.
The addition of alloying metals improves strength and durability while maintaining the precious metal content associated with sterling silver.
