Are all your jewellery items Hallmarked?

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 HSC DIAMONDS is registered with the LONDON ASSAY OFFICE, ensuring our precious metal jewellery is compliant with the UK’s hallmarking regulations. All our stock is subject to an internal check process to ensure it meets the UK’s hallmarking regulations before it is 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.
