Gold & Hallmark Education
Understand what a UK hallmark is, how to read one, and why independent hallmarking gives you confidence that your gold is genuine.
Why this matters
In the UK, qualifying gold pieces are independently tested and hallmarked under the Hallmarking Act 1973. The hallmark confirms the metal's fineness — 375 (9ct), 585 (14ct) or 750 (18ct) — so you can trust that solid gold is exactly that. The guides below explain the marks, the law and how it protects you.
