Hallmarking

What is Hallmarking?

Hallmarking is an official stamp of quality guaranteeing that you are getting the exact purity of metal that you have purchased.

Here at Durham Rose we send your pieces to the trusted Sheffield Assay office for certification and hallmarking. Other locations for hallmarking are in Edinburgh, London and Birmingham each represented differently in the hallmark by distinguishing symbols.

Hallmarking is a necessary process that all jewellery manufacturers are obliged to do and this is an important element of the production process that ensures quality and certifies the value of your ring. This is necessary for some insurance companies and for ring valuations.

 

 

Understanding your Hallmark

Your ring will be marked with a number of symbols which are;

  • Durham Rose Sponsor’s Mark: formally known as a Maker’s Mark
  • The Standard Hallmark Mark: demonstrating the standard of finesse, i.e. the purity of the precious metal content in parts per 1000.  For example, 18 carat gold is 750 parts per 1000 by weight
  • The Assay Office Mark: showing which Assay Office tested and marked the item – we use the Sheffield Assay
  • The Date Mark:  defined by a stamped letter shows the year in which the article was hallmarked

This is what this information would look like on the inside of your piece;
