British Hallmarking Council (BHC) & Assay Offices (London, Birmingham, Sheffield, Edinburgh)
United Kingdom Gold-Filled & Jewelry Regulatory Standards
In the United Kingdom, precious metal descriptions are strictly governed by the Hallmarking Act 1973, overseen by the British Hallmarking Council and enforced by Trading Standards. Crucially, under UK law, 'Gold Filled' items CANNOT receive an official precious metal hallmark because the core metal is non-precious (brass/bronze). Describing an unhallmarked item as 'gold' without immediate qualification is a criminal offence under the Act. To comply legally when selling in the UK, retailers must clearly describe the item as 'Gold Filled' or 'Rolled Gold' and NEVER use the solitary word 'Gold' or imply that the article is solid gold. If an article features sterling silver with gold cladding or heavy plating (≥2.5 microns, ≥375 fineness), it may receive a silver hallmark with 'Vermeil' description.
