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 Annie Haak Designs mark
  • Metal and fineness (purity) mark
  • Assay office mark

Assay Office London (with whom Annie Haak Designs is registered) also applies two optional marks,

  • Date mark
  • Traditional fineness mark (925)


Pieces of jewellery (this includes our individual charms) what fall under 7.78gms in weight are exempt from hallmarking.

Annie Haak Designs

All Annie Haak Designs silver jewellery is 925 sterling silver and bears the 925 fineness mark regardless of its weight.

Annie Haak Designs fully complies with the 1973 Hallmarking Act and is registered with the London Assay Office, who independently tests and guarantees that our jewellery is 925 sterling silver, and carries out the hallmarking.

All our pieces of jewellery that weigh over 7.78 gms (generally our larger pendants) are hallmarked as required.

You can find more information about hallmarking on the London Assay Office website:

Gold items

Annie Haak Designs gold jewellery range is Assay Assured and created using high quality materials.

The gold beads used in our jewellery are ‘gold bonded’. This means the beads are brass based and bonded with gold 14 carat outer coating. We have chosen to use the more expensive ‘gold bonded’ as opposed to ‘gold plated’ technique due to our stringent testing for quality and longevity, as it is generally considered that ‘gold bonded’ beads are harder wearing.

What is the difference between gold plated and gold vermeil ANNIE HAAK charms?

We work closely with a very reputable company in Hatton Garden where our gold charms are taken to be plated.

Our ‘gold’ charms are brass based and plated with 14 Carat gold to the depth of 2.5 microns.

Our ‘gold vermeil’ charms have a base of sterling silver and are plated with 14 Carat, 2.5 micron, gold.
