• Consists of a series of marks applied to articles of the precious metals platinum, gold, palladium and silver

• Means that the article has been independently tested

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

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

All four Assay Offices have a legislative remit to control standards of precious metal being sold in the UK. They do this by assaying (testing) the precious metal content, then applying the hallmark. It is a legal requirement for silver over 7.78g, gold and palladium over 1g, and platinum over 0.5g to have a UK recognised hallmark.

Look for the hallmark on our designs: Blue Fyre is proud to hallmark in London.
