Hallmarking

Hallmarking sterling silver jewellery

Under the 1973 UK Hallmarking Act all sterling silver jewellery that weighs over 7.78 gms must be hallmarked at one of the UK’s assay offices.

What is a hallmark? 

A hallmark:

  • Consists of a series of marks applied to an article of precious metal
  • Means that the piece of jewellery has been independently tested
  • Guarantees that the piece of jewellery conforms to all legal standards of purity (fineness)

A complete hallmark consists of three compulsory punch marks:

  • Sponsor's mark – our unique brand name
  • Metal and fineness (purity) mark
  • Assay office mark

 

Hallmarking registration

We are registered with the London Assay office for Hallmarking, and products that are above the stipulated weight will be Hallmarked.
