Learning About Fake Gold and Hallmarks

One of the biggest jewelry problems I’m hearing about at the moment is buyers purchasing fake gold over the internet, at markets/ fairs and even occasionally in shops.  Here are some helpful tips to consider when purchasing gold in the United Kingdom:

1. If it’s too good to be true it usually is!

2.  Only buy gold that has been hallmarked at a British Assay Office. This means the gold has been tested and is real.

3. If buying from a ‘real world’ market stall, fair or shop don’t assume the jewellery item you are seeing is gold (even if it looks gold and is with other labelled gold items). An unscrupulous trick is to place a few non-hallmarked fake gold tone rings on a ring display pad mixed with real British hallmarked gold. 

These ‘jewelers’ will label a ring as simply (eg) GARNET ETERNITY RING, and place it on a display pad with other rings labelled ‘9ct topaz gold ring’. Now, the ‘garnet eternity ring’ does have a real garnet in it, and looks gold. And the seller will charge the same price for it as the surrounding rings, which are genuine hallmarked gold, so buyers simply assume it’s another solid gold ring on a pad of other gold rings. But its not.

Notice the wording – no mention is made of gold. It’s actually a dirt cheap garnet stone in a goldtone pot metal ring, and because the seller hasn’t described this particular garnet ring as gold (remember, they simply labelled it ‘Garnet Eternity Ring’) they’re not breaking any law, as far as I know. Do this with 4 costume jewellery rings on one display pad with 16 other real gold rings, and that’s a nice extra profit for dodgy sellers.


4. Gold jewellery in the UK comes in 4 finesses: 9ct (375)…….14ct (585)…….18ct (750)……22ct (916). All non-antique gold over 1 gram must carry a British Assay Office Hallmark. A simple (for example) ‘750’ or ’18k’ stamp on its own is not a proper hallmark, and is not allowed to be called gold or sold as gold in the UK.

ABOVE: This ring has a simple ‘9ct’ stamp. It is not hallmarked, and therefore cannot be legally called 9ct gold or sold as gold (unless it is a genuine antique, which is where things get complicated and I suggest you seek expert advise).

ABOVE: a proper set of British hallmarks, which means this ring can legally be sold as/ called 9ct gold.

5. 10k Gold is not a legally recognized finesse in the UK. The precious metal laws are tough here and so are the punishments – don’t describe any jewellery to sell as ’10k gold’ if you are based in the UK.


If in doubt, always ask a seller about the hallmarks on a piece of fine jewellery.
