A Hallmark is a mark or a series of marks that are stamped onto certain metals to certify their preciousness and purity.
We have read all the hallmarks on our jewellery as accurately as possible. Please note due to the age of some of our pieces often the hallmarks have become worn and can be difficult to see.
If you have any questions regarding the hallmarks on any of our pieces please get in touch email@example.com
The PI London Glossary
Hallmarks are something that we find fascinating, they are like a secret coded message.
In order to help you decipher the code we hope our hallmark glossary helps. Hopefully you will be able to start decoding hallmarks on other pieces you see, we’d love to hear how you get on.
There are 4 assay offices still in use in the UK:
Birmingham (Anchor symbol), Sheffield (Rose), London, (Leopard)Edinburgh (Castle)
If your gold is inscribed with the ‘375’ hallmark, it means that it is 37.5 per cent solid gold, 9 carat or 9ct gold for short.
The ‘500’ hallmark, means that it is 50 per cent solid gold, or 12ct.
The list goes on, ‘585’ is 14ct, ‘625’ is 15ct, ‘750’ means 18ct, ‘916’ is for 22ct and ‘999’ which is the purest gold you can get is 24 ct.
The age of a piece of jewellery is indicated by letters of the alphabet.
The alphabetic sequences are also differentiated by changes in typeface, punch shape, and changes from upper to lower case characters.
Here at PI London all of our pieces are 9ct (375) gold or more.
We will never have plated or gold filled pieces as we believe jewellery should last a lifetime.
