The Importance of Hallmarking

What is a Hallmark?

It is a quality control mark engraved on precious metals indicating that it has been tested independently and conforms to the standard of precious metal content or fineness. 

Think of it as a Quality Check (QC) mark.


It’s an Official Stamp of Quality

In other words, it indicates that a product or metal is checked and certified for its purity and quality.
