Welcome to WaarborgHolland!

Who are we?

WaarborgHolland is an independent Assay Office situated in The Netherlands, appointed by the Ministry of Economic Affairs and Climate Policy, and charged with carrying out the Dutch Hallmarking Act (Waarborgwet). This law prescribes that precious metal items - such as a gold ring - must be provided with a hallmark before being sold or promoted to consumers.

What do we do?

We test whether your item is truly made of precious metal and whether the fineness is high enough to meet the legal standards. If this is the case, we apply the hallmark either by means of a stamp or by laser. The hallmark acts as a certifcate to guarantee that the ring is actually made out of gold. Now that is a comforting thought.

How can we help you?

We are here to get your jewellery sales up and running. From high-end luxury retailers to your local jewellery shop on the street, we provide our services to everyone, everywhere. With our Dutch national hallmark, you are free to sell your jewellery not only in The Netherlands, but across almost whole of Europe. We help you set up your logistics and distribution processes, guide you through the hallmarking requirements and make sure you comply with legal standards. Want to get started?
