BBC One, Fake Britain

In January 2019 we welcomed a film crew from BBC One's Fake Britain to Goldsmiths' Hall and the Assay Office.  The footage was aired last night on episode 4, series 9 of the popular consumer show.

During filming, presenter Michelle tried to pick out a counterfeit bracelet from a group, and she and Dave met members of the public who brought their jewellery for examination. 

The BBC strapline for the show was "Michelle is with the experts as they tell members of the public if their precious jewellery is a genuine gem or a worthless fake."

Catch the show here.
