Hallmarking is the independant verification of the precious metal content in an article.
The 1973 Hallmarking Act makes it unlawful to describe an item over a certain weight as gold, silver, platinum or palladium without an independent Hallmark
- All Silver articles weighing more than 7.78 grams must be hallmarked
- All Gold articles weighing more than 1 gram must be hallmarked
Articles below these exemption weights may be described as Gold, Silver, Palladium or Platinum without the need for a hallmark.
All of the SilverCraftistry jewellery that requires hallmarking is sent to the London Assay Office who test the purity of the metal and ensure it conforms to the standards set down by the law before applying the markings.
