Hall Marking

  1. Why Hall Mark?
    Hallmarking can be dated back to 1300 when it was introduced to protect the public and traders against fraud. As silver has to be alloyed with other metals to be workable, hallmarking was put in place to check the levels of silver and other metals used. All silver tested and hallmarked as 925 Sterling Silver is 92.5% silver with 7.5% copper. Hallmarking of precious metals is a legal requirement in the UK. If it has a hallmark you can be sure you are getting the genuine article.
  2. Current Hallmark Symbols
    Until 1998, a Hallmark consisted of four compulsory Marks. The Sponsors Mark The Finesss Mark The Assay Office Mark and The Date Mark Since 1998 the date Mark has become optional but the other three symbols remain compulsory.
  3. The Sponsor Mark
    The Sponsor Mark for Twisting Silver Jewellery is the initials TS inside a diamond shaped frame. Twisting Silver Jewellery is Hallmarked at Birmingham Assay Office. For More information on Hallmarking click on the link to Birmingham Assay Office.
  4. The Birmingham Assay Office
    The Birmingham Assay Office was founded in 1773 by an Act of Parliament. Silversmithing at this time was a booming business in Birmingham producing buttons, buckles, spoons and other small articles. It is the largest Assay Office in the World. There are now four Assay offices in the UK - Birmingham, London, Edinburgh and Sheffield.
  5. Silver
    Silver is one of the most beautiful and versatile of traditional decorative metals. It has been extracted from earth and used in jewellery, tableware, utensils, items of beauty and currency coins since ancient times. It is a soft white lustrous metal with the chemical symbol Ag, occurring naturally in its pure free form (native silver), as an alloy with gold and other metals, and in other minerals. Silver in its pure state is not suitable to use as it is too soft but by alloying it with other metals it can be hardened and then used to make jewellery and other articles.
  6. Optional Marks
    The maker has the option of adding any of the following marks (these are not required by law) :- Traditional marks - Any Traditional Marks on British articles over the centuries can be added. Date Letter - This will tell you in which year the article was tested and marked.

The most recent mark is to honour the Queens Jubilee in 2012. Optional Pictorial Marks - From 1999, pictorial marks have been optional and can be added to the figure of parts per thousand. Description
