Send us your Hallmarking

The UK has had laws relating to the compulsory, independent hallmarking of Gold and Silver products for over 700 years.  These laws have an impact on anyone importing or selling products within the UK.  Products made from gold, silver or platinum have to be independently tested and hallmarked before being placed on the market and described as such unless they are exempt because:

1.The product weighs less than
• 1 gram for Gold
• 7.78 grams for Silver
• 0.5 grams for Platinum

2. The product has already been tested and hallmarked in a country which is a signatory to the International Convention on Hallmarking and it bears the Convention ‘Common Control Mark’.  For further information click here.

3.The article bears another National Hallmark which provides an equivalent guarantee to consumers.  For further information relating to National Hallmarks acceptable in the UK, click here.
