Our Commitment to Hallmarking

When it comes to manufacturing jewellery and silverware, precious metals (silver, palladium, gold and platinum) are rarely used in their purest form. Instead they are usually alloyed with lesser metals to achieve a desired strength, durability, and colour.

It is not possible to detect the precious metal content of an item by sight or by touch. It is, therefore, a legal requirement to have items consisting of silver, palladium, gold or platinum independently tested and then hallmarked before they can be described as such. Items must bear a hallmark at point of sale, subject to the following weight exemptions:

Silver: mandatory for items above 7.78 grams; gold: mandatory for items above 1 gram; palladium: mandatory for items above 1 gram; platinum: mandatory for items above 0.5 grams.

ASR Gems is registered with the Assay Office London, ensuring our precious metal jewellery is compliant with the UK’s hallmarking regulations. All stock is subject to an internal confirmation process to ensure it meets the UK’s hallmarking regulations before it is dispatched to our customers.
For articles that are below the UK hallmarking Act’s mandatory weight for hallmarking ASR Gems operates a separate due diligence process which involves periodic voluntary testing of items that fall below the mandatory weight to ensure they meet the minimum fineness requirement.

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.
