How to read a European gold hallmark

The small marks that tell you where a piece was made, when, and in what karat.

European gold is rarely stamped the way American gold is. Instead of a simple 14K, you will often find a cluster of tiny pictorial marks: a standard mark for the karat, a maker's mark, and sometimes a date letter or a city mark.

Dutch pieces carry a lion for 750 gold and a crowned figure for lower standards. French work uses an eagle's head for 18 karat gold, and a boar or a crab for silver. British hallmarks are the most complete of all, with a full date letter that pins a piece to a single year.

We photograph the hallmark of every piece we sell and read it out for you during a video viewing. If a mark is worn beyond reading, we test the metal and say so plainly in the description.

See it before you buy it

Every piece is unique. One of our specialists will show it to you in daylight on a private video call, in your own time zone.
