What makes a Hallmark Proof™

A Hallmark Proof™ is your guarantee of quality that will last a lifetime.

  • Each Hallmark ProofTM is struck from 12.85g of sterling silver
  • Every Hallmark ProofTM is minted to the very highest standards, using traditional techniques dating back centuries to ensure the fine proof finish
  • The obverse design represents what all Hallmark ProofTM pieces draw together in Latin – ‘Orbis Terrarum’ – The World, ‘Historiae’ – History, ‘Culturae’ – Culture and ‘Artis’ - Art
  • The very latest minting techniques allow the intricate addition of a dramatic colour

Understanding your Hallmarks

Each Hallmark ProofTM is officially hallmarked by the London Assay Office. Each hallmark provides essential information about the piece. Here’s what each hallmark represents:

  1. The Standard Mark: Confirms the metal purity; for sterling silver, this is 925, indicating 92.5% pure silver
  2. The Maker’s Mark: Identifies the company or individual responsible for the item
  3. The Assay Office Mark: Represents the London Assay Office, depicted as a leopard’s head

These marks are your guarantee that the piece is made from high-quality silver and has been tested for purity.
