the international hallmark in accordance with the Convention of 15 November 197212 on the Control and Marking of Articles of Precious Metals.
A double mark is the combined Swiss/international hallmark. The double mark is applied as a single unit. The fee for a double mark is charged even if individual marks are applied separately and by the manufacturer itself.
