Authentication FAQ

    How to tell if gold is real?

    Check UK hallmarks and assay marks, weight, and colour consistency. Magnet and bite tests are unreliable because plated pieces can fool them. For valuable jewellery, use professional authentication with documented results.

    Hallmarks and stamps

    UK gold should carry fineness marks (375, 585, 750, etc.) and often a sponsor mark. Compare font and depth to known authentic examples for the brand.

    Unbranded scrap gold may still need assay office testing for a legal proof of purity.

    When to authenticate professionally

    Branded pieces from Cartier, Tiffany, or high-value chains benefit from brand-specific authentication, not just a magnet test.
