Upcycling isn’t just the practice of transforming old materials into useable objects, it is the process of breathing a new lease of life into well used and loved items to give them a new story and personality. All this while at the same time creating something that is useful, functional and beautiful.

But what are the rules regarding altering an item of precious metal which bears an existing hallmark? Are you unintentionally breaking the law?

For items which have been re-worked to change their use (for example a silver fork becoming a bangle), you need to submit them to an Assay Office for authorisation. We will examine the article, identify the original hallmark and issue a certificate signed by the Assay Master.

For other alterations, the following conditions apply:

Any other alteration must be re-submitted to an Assay Office for testing.
