Other marks

Articles of precious metals may also bear other marks provided that they are not confusingly similar to the mandatory or voluntary marks. They must not give the consumer a false impression of the articles. Articles of precious metals may also bear marks used by other states, but they must not be misleading to consumers.


The seller of articles made of precious metals is responsible for ensuring that the articles on sale carry such marks as allow the traceability of the responsible party. Ultimately, the seller is responsible for the products that they sell. The products must carry all the mandatory marks required in Finland.


Articles made of materials other than precious metals may not bear marks that are used on articles of precious metals, not even marks that are confusingly similar to such marks. For example, brass rings bearing the mark 18k or 750 cannot be released onto the market before such marks are removed from the ring. As an exception, the responsibility mark may also be applied on items other than articles of precious metals (e.g. bronze jewellery, pewterware, and plastic bags). However, it cannot be applied on articles that might suggest that they are articles of precious metals.


Replacing marks with a certificate

If an article of precious metal intended for sale bears no statutory marks, the following organisations may replace the marks with a certificate:


  • Finnish customs
  • Debt collection authority
  • Auction house
  • Pawnshop
  • Bankrupt's or deceased person's estate
  • Assay office in the case that the article is damaged or its value would decrease through marking.


The real fineness of article of precious metals can be determined using an analysis method suitable for the item in question (for example, using X-ray fluorescence spectroscopy, XRF for short, cupellation, titration, or a gravimetric analysis.) Based on the analysis, the real fineness of an article of precious metals is entered in the certificate.
