In addition to the fineness, hallmarks can show where and when an item was hallmarked, and under whose name it was submitted.

A hallmark is a separate stamp made by an assay office – in countries that have an assay office. In many cases, as with French jewelry or Swiss watches, you’ll find both maker’s marks and hallmarks. Buying jewelry from countries with a hallmarking system offers more of a guarantee, if you can decipher the marks. You’ll find animal heads on French jewelry, for example, a numerical code on British jewelry, and a combination of symbols and numbers on Russian jewels. A good appraiser can help and it’s always wise to buy from trusted dealers who offer written guarantees.

But any serious collector should have a jeweler’s loupe and a decent hallmarking guide, and start learning to decipher the code.

Other assay offices were later opened in centres where goldsmiths worked.

The UK is among 19 countries that belong to the Hallmarking Convention, formed in 1976 to create a set of standards for assay offices so jewelry wouldn’t have to be re-tested every time in crossed borders.

If it was made in England before 1975, 18k gold will be stamped 18ct or 18c. S., you will usually find a mark identifying precious metal content, but because there is no official system in place to verify this, it’s not uncommon to find a piece of jewelry stamped with an inflated weight.

Larger firms with established brands are not likely to indulge in “under-karating,” but mass-market manufacturers sometimes will – one reason to stick with recognizable names and get familiar with their maker’s marks.

Whether you want to buy or to sell jewelry or watches, the first step in figuring out value is to identify what it is, when and where it was made, and by whom.
