Hallmarking | What is a Hallmark?

A Hallmark is a small marking that is stamped onto a precious metal to guarantee that it conforms to standards of purity and has been independently tested.

It is impossible to verify the precious metal content of a piece of jewellery by merely looking at it by sight or by touch. It is therefore a legal requirement that items made from platinum, gold, palladium or silver much be independently tested and then hallmarked in order to be described as such.

Fineness of Our Metals

All Purely Diamonds rings and jewellery are hallmarked at British Assay offices ensuring our precious metal jewellery is compliant with the UK’s hallmarking regulations. All items are subject to an internal confirmation process to ensure they meet the UK’s hallmarking regulations before they are dispatched to our customers.

We are an Assay Assured Jewellery Retailer. Assay Assured status is only given to retailers who have been independently audited and verified by Assay Assured which is run and overseen by the Edinburgh Assay Office, and ensures that all precious metal jewellery (except items exempt by weight) are independently tested and hallmarked.
