"In the UK it is illegal to sell or describe any item as Gold, Silver,
Platinum or Palladium unless it is hallmarked. A UK hallmark is added by an
independent assay office and guarantees the precious metal content of the
item you are buying. Sellers in contravention of the law may be prosecuted
and could face fines or imprisonment."
When delivery is to an EU member state, Israel, Norway, or Switzerland we
will add the widely recognised international "Convention" hallmarks. For all
other overseas deliveries, including the USA, the fineness of the precious
metal will be engraved inside each ring. However, should you wish UK
hallmarks to be added please let us know at the time of order.
