The golden wedding anniversary is 50 years of marriage. Year 50 is gold on the British list.
That is the answer. The rest of this page covers the thing most families get wrong about the fiftieth, and what the marks on a piece of gold tell you before you spend serious money on one.
The golden wedding and the King's message
A golden wedding does not get a card from the King.
GOV.UK sets the threshold at the diamond wedding, and fifty years is ten short of it. What qualifies, how to apply and the deadlines are on the diamond wedding page.
There has been exactly one exception, and it was deliberately a one-off: for 1997 only, The Queen sent messages of congratulation to couples married in the same year as she was, to mark their golden weddings.
If a Royal message matters to the family, the anniversary to plan for is the 60th - how to apply, and the deadlines.
Why 50 is one of the two oldest anniversaries
The golden wedding is not a modern invention, which sets it apart from most of the list.
It is one of a pair. Debrett's describes both the 25th and the 50th being marked in the Middle Ages with silver and gold wreaths - comparatively rare events, it notes - and the golden wedding is the older half of that pair by twenty-five years. Everything sitting between them arrived later, and the silver wedding page traces how the run of years got filled in.
So the golden and the silver weddings are the two anniversaries with genuine history behind them. That is roughly why they remain the two that reliably get a party rather than a dinner.
What the hallmark on gold guarantees
If the gift is real gold rather than gold-toned, the mark is worth ten minutes, because at fiftieth-anniversary budgets the difference is real money.
Under the Hallmarking Act 1973 it is a criminal offence to describe an article as gold when that is untrue, and an approved mark means a UK Assay Office has independently tested the metal, certified its purity and recorded who submitted it. Very little else on sale carries a legally enforced guarantee of its own composition.
The mark is made up of five components, three of them compulsory. Rather than repeat the breakdown here, the full anatomy - sponsor's mark, millesimal fineness, Assay Office mark, fineness symbol and date letter - is set out on the silver wedding page, and it reads the same on gold as it does on silver.
The date letter, and a gift no shop will offer you
One component does specific work at a fiftieth. The date letter records the year of hallmarking, and because every punch is destroyed at the end of its year, a hallmarked piece can be dated exactly from the metal itself. So there is a golden-wedding gift no shop will offer you: a piece of hallmarked gold whose date letter is the year the couple married. Fifty years old, the same age as the marriage. How the letters cycle, and how to read one, is set out on the silver wedding page.
Gold fineness, and the weight that makes a stamp meaningless
The gold finenesses recognised under the international Hallmarking Convention are 375, 585, 750, 916 and 999 - parts of gold per thousand. Gold is also sold by carat in ordinary conversation, but the fineness number is the one with legal force behind it, and it's the one stamped on the piece.
Gold carries a low exemption threshold: an article is exempt from hallmarking if it contains less than 1 g of gold, against 7.78 g for silver. Only platinum sits lower, at 0.5 g. Below that, a purity stamp is the maker's own claim rather than an Assay Office test. A thin chain or a light pair of studs can sit under 1 g.
Commemorative marks, and buying gold from abroad
Two more things apply to gold exactly as they apply to silver, so rather than repeat them: the optional commemorative marks struck for a handful of national occasions, and the import rules that decide whether a foreign mark counts in Britain. Both are explained on the silver wedding page. The one gold-specific note is that a piece bought abroad and re-worked here - resized, re-shanked, soldered - can need re-hallmarking, because the mark certifies the article as submitted, not the metal in the abstract.
What a fiftieth gets given
Gold, gold-dipped, gilded or gold-coloured all read correctly; after fifty years nobody is auditing the carat. What marks this milestone out from the others is scale - the fiftieth is usually the one that gets a real event, a real budget, and a gift the whole family has pooled for.
The failure mode is a present that is only about the number. Fifty years is the occasion; the two of them are the subject.
Where fifty sits in the sequence: the whole UK list, year by year. For ideas and budgets see our golden wedding anniversary gifts; the silver wedding is the 25th and the ruby wedding is the 40th.
