IT IS THE ASSAY OFFICE THAT GUARDS THE CREDIBILITY AND THE PURITY OF AN ASSAY.

Assay office is a central government body which verifies and certifies the amount of a pure noble metal contained in a ready-made product.

Assay office certifies an assay by stamping or laser-imprinting a mark - the so-called hallmark. Vendible goods which are made out of noble metals undergo mandatory hallmarking. The only exceptions are goods made out of gold weighing up to 1 gram and silver weighing up to 5 grams. These particular goods do not have to possess hallmarks.
