What is a Hallmark?

A hallmark:

• Is a set of component marks applied to articles of the precious metals gold, silver, platinum or palladium.

• Means that the article has been independently tested.

• Guarantees that it conforms to all legal standards of purity (fineness).

• Guarantees provenance by telling us where the piece was hallmarked, what the article is made from, and who sent the article for hallmarking. 

The standard hallmark formation is horizontal with minimal spacing between the marks.  

Other formations of these hallmarks, often called "bespoke" or "display marks" are available.
