Hallmarking

WHAT IS A HALLMARK?

Hallmarking is a system of quality control and assurance used to verify the purity and authenticity of precious metals such as Gold and Sterling Silver. Hallmarking involves a series of marks applied to a piece of jewelry or silverware which indicate its composition, place of origin and the mark of where it was tested. This system has been in place for centuries and is an important part of the jewelry industry.

In the US & Canada, jewelers hallmark products themselves, as opposed to Assay Offices that are used in Europe. Serge DeNimes follows the European style of marking, which are similar to European marks, so they may look different to the marks you are familiar with.

Every Serge DeNimes jewelry item has been tested and verified, which means you can trust that every item you buy from us is made from Sterling Silver, as they have been marked with our unique hallmarks.
