Certification & Hallmarking

Our treasures are made of only the finest materials and are certified by the The Portuguese Mint and Official Printing Office (INCM) which ensures the highest quality standards. The assay mark guarantees the quality of items that are made with precious metals such as gold, silver, platinum, and palladium. It is an international mark that has the same legal status as national official marks.
