In The Netherlands all precious metals by Dutch law have to be assayed by an official office, that is recognized by the Dutch Government. The assay of precious metal content has been carried out for more than 600 years, and it is one of the oldest form of Dutch consumer protection.
Currently there are two offices in The Netherlands who can carry out the assay of precious metals.
