Hallmarking Information

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 weight exemptions below.

Astrea London is registered with the Assay Assured Jewellery Retailer scheme, ensuring our precious metal jewellery complies with the UK's hallmarking regulations. All stock is subject to an internal confirmation process to ensure it meets those regulations before it is dispatched to our clients.

For articles below the UK Hallmarking Act's mandatory weight, Astrea London operates a separate due diligence process involving periodic voluntary testing to ensure they meet the minimum fineness requirement.
