ERA Jewellery

Hallmarking

What is hallmarking? The metals used to make the jewellery are too soft to work with in their pure form. To harden the metals they are mixed with another metal such as copper to create a harder alloy more suitable for working with. Just by examining the metal, it can be impossible to determine the quality of the metal and where it came from.

This is where hallmarking comes in. Each hallmark consists of four details.

  • The maker's insignia in my case ERA.
  • Where it was hallmarked e.g. Yorkshire Rose for Sheffield.
  • The type of metal e.g. Stirling silver denoted by a walking lion and the number 925.
  • A letter dating the piece. The case, font and the shape of the container surrounding the letter are all taken into consideration.

And here is an example -
