How can EWN help you?

EWN has been appointed as Assay Office by the Dutch Ministry of Economic Affairs and Climate Policy under the Assay Act.
The Assay Act requires that ornamental and utility articles of precious metal intended for the Dutch market must be tested by an independent body.
Assay Office EWN is charged with this task as an independent administrative body.

EWN for gold and silversmiths

When you have finished a piece of jewellery, the correct test marks need to be applied. This may be done in the traditional way by stamping, or by a modern laser mark. And the customer may like a special, meaningful engraving.
