Hallmarking is compulsory for all silver items weighing above 7.87 grammes sold in the UK and all gold items weighing above 1 gramme.
Items for hallmarking have to be sent to a UK assay office for testing and marking.
As my items are all handmade to order rather than stock items I do not currently hallmark most items under those weights.
However any items can be hallmarked for an additional charge.
Items above those weights such as gold rings/pendants/stock pins are all hallmarked on completion which is included in the price charged.
This means sending the items to the assay office which takes about an extra 3 days.
