Hallmarking

As legally required, all silver jewellery weighing more than seven grams and all gold jewellery are hallmarked at the London Assay Office. My registered hallmark is MdW.

A hallmark:

  • Is a set of component marks applied to articles of the precious metals gold, silver, platinum or palladium.
  • Means that the article has been independently tested.
  • Guarantees that it conforms to all legal standards of purity (fineness).
  • Guarantees provenance by telling us where the piece was hallmarked, what the article is made from, and who sent the article for hallmarking.
