Everything you need to know about gold hallmarking in UK

Rules governing gold hallmarking in UK

Gold in its purest form is extremely soft and infinitely malleable. Thus, it is mixed with lesser metals to achieve the desired strength, colour, etc. required for use in jewellery or various other items. But the extent to which gold is mixed with others cannot be possibly observed with the naked eye. Therefore, a hallmark is needed to inform buyers of the purity of their purchase.

But did you know that gold hallmark signs vary from country to country?

In the UK, all gold products need to be hallmarked before they are sold in the domestic market. The marking mandates recognition of the sponsor, purity, and the assaying office. Some items also carry the date of hallmarking

  • Compulsory marks

    • The sponsors mark is the unique mark of the company or person responsible for sending the article for hallmarking. It could be the original manufacturer, importer, wholesaler, retailer or an individual registered with an Assay Office.
