Hallmarks are small
markings stamped on gold, silver and platinum articles. A
Hallmark means that the article has been independently
tested and guarantees that it conforms to all legal
standards of purity (fineness). These tests are carried out
only by an Assay Office, of which there are four in the UL –
London, Birmingham, Sheffield and Edinburgh.
The Hallmarking Act
1973 changed on 1 January 1999 and allows articles of higher
and lower standards of fineness to be sold. This brings UK
law into line with European law. Consumers may now choose
from a much wider range of goods but to continue to benefit
from the same level of protection.

Offices of London, Birmingham, Sheffield, and Edinburgh from 1678 –
