The Guarantee of Precious Metals and Hallmarks

Works made of precious metals (composed of gold, silver or platinum) are sensitive works given the cost of the metals used in their composition.

This is why they are subject to special supervision through the so-called rules of "precious metals guarantee" .

The guarantee offices ensure the control and marking of works in precious metals.

Their mission is in particular to ensure the conformity of the title of works in precious metals and to mark them with the guarantee hallmark if they are of legal titles.

The Guarantee hallmarks

To identify a precious metal, a hallmark is affixed to the jewelry.

Only state-accredited companies can certify the metal content of the work.

In France, only jewelry weighing more than 3 g of gold must be hallmarked.

There are two types of punches commonly found: :

The master's mark
It allows you to recognize the jeweler who made it.
It is notable for its shape containing the initials of the craftsman.

Before affixing or affixing themselves the guarantee mark on the works they hold, professionals must first affix the mark which identifies them as a professional, namely: master's mark if they are manufacturers

The title punch
It guarantees the alloy.
Only the customs service is authorized to pose it. It changes depending on the metal used and the quality of the alloy.
