A small symbol with great meaning
A hallmark is a mark on a precious-metal item. It helps you understand fineness and how the piece has been checked.

What to look for in jewellery
Fineness expresses the proportion of precious metal in an alloy. A fineness number, maker's mark and official hallmark are not the same — we will gladly explain the markings on your jewellery at handover.
Current overview from the Assay Office
We recommend checking valid hallmark designs and hallmarking rules directly with the Czech Assay Office. Each product page states the material; the exact fineness and other specifications must be confirmed in the product specification before ordering.
