In the UK it is illegal to sell or describe any item as Gold, Silver, Platinum or Palladium unless it is hallmarked*.
A UK hallmark is struck by an independent assay office and guarantees the precious metal content of the item you are buying. Sellers in contravention of the law may be prosecuted and could face fines or imprisonment.
The Hallmark comprises three compulsory marks:
The registered mark of the company that submitted the article for hallmarking.
Tells you the precious metal content, expressed in parts per thousand.
|Gold:||9 carat||14 carat||18 carat||22 carat|
Assay Office Mark
Tells you which Assay Office tested and hallmarked the article.
You may see optional marks, such as the traditional fineness symbol and the date letter depicting the year the item was hallmarked.
Traditional Fineness Symbols
|Sterling Silver||Sterling Silver Scotland||Britannia Silver||Palladium||Gold||Platinum|
International Convention Marks
This mark is used by countries, including the United Kingdom, that are signatories to the International Convention on Hallmarking and is recognised by all those countries.

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.
Swag is registered with the Edinburgh Assay Office, 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 Swag 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.
