In Switzerland, all silver jewelry must have a hallmark to guarantee the authenticity and quality of the silver. This stamp contains the maker's mark or the name of the person responsible and the silver content of the piece of jewellery.

​

The responsibility stamp is a legal requirement and is issued by the Swiss Precious Metals Control. The control ensures that the responsibility stamp is properly applied to the piece of jewelry and that the piece of jewelry meets the legal requirements.

​

It is important that the hallmark of responsibility is placed on any piece of silver jewellery, as this gives customers the assurance that the piece of jewelery was made by a responsible manufacturer and that the silver is of high quality.
