925 Sterling Silver Hallmark

In the UK, hallmarking has a long history, dating back nearly 700 years, and representing the earliest form of consumer protection. The consumer benefits in many ways.

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 UK - 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 chose from a much wider range of goods but continue to benefit from the same level of protection.

It is illegal for any trader to sell or describe a precious metal as gold, silver or platinum unless it is hallmarked. Gold articles weighing less than 1 gram, silver articles weighing less than 7.78 grams and platinum articles weighing less than half a gram are exempt from hallmarking.

All our sterling silver jewellery is stamped with the fineness mark 925 which guarantees that the jewellery you are buying is of the highest quality and complies with current hallmarking law.
