We offer in-house hallmarking service for European Countries that accept the Dutch hallmarking system (* Each countries’ regulation applied, please contact us for more details).
Jewelry can be hallmarked within the factory . Sampling and testing is performed by the WaarborgHolland during production processes to ensure that the fineness of the precious metal we use is up to standard. Finally, the stamping of the hallmarks is performed by WaarborgHolland in house, so there is no need to go to your national assay office anymore.
This paid service provide a unique convenience and saves time and logistical costs as you can distribute your jewelry immediately.
