Hallmarking - Assay Marks


We are fully registered with the Birmingham Assay Office with a Sponsor Mark Number, this guarantees all pieces made by us are legally Assayed and Hallmarked. You can be sure your silver or 18ct Gold Plated silver jewellery supplied by us is of the highest standard.


All solid sterling silver 925 products we sell over the legal weight threshold of 7.78g will already be hallmark stamped and tested at Birmingham Assay office.


Once an item is hallmarked it cannot be changed without it being sent back to the Assay Office, this will incurr an additional charge of £55 per item.


It you require your silver products which are under the legal required weight threshold of 7.78g Hallmarked. This has to be charged for as an extra and will incurr an additional charge of £55. Please detail this as an additional requirement on your order form and don't forget to add the amount to your payment total.


Precious metals used in jewellery and giftware manufacture are always used as an alloy. The precious metal must be mixed with other elements to give it the necessary properties such as flexibility to produce a desirable and durable article.
Even the most experienced jeweller or chemist cannot tell how much precious metal there is in an alloy, just by looking at it, nor whether a thick plating of gold is covering a base metal interior. Due to the high price of precious metals, this offers a huge opportunity for fraud and there has therefore always been a need to protect the public, and honest suppliers, from those who are tempted to cheat them.
Therefore all items being sold as gold, silver, platinum or palladium in the UK must be hallmarked to confirm that they meet the legal standard. This cannot be done by the manufacturer or importer; goods must be submitted to one of the four UK Assay Offices, or an Assay Office belonging to the International Convention.
The only items which are exempt are those which are under the legal weight threshold:
  •  0.5 grams for Platinum
  • 1 gram for Gold
  • 1 gram for Palladium
  • 7.78 grams for Silver
