SOPRO Jewellery pieces are produced in Portugal in compliance with all quality criteria. The precious metals used are duly certified by the INCM Assay Office.
The INCM Assay Office provides this guarantee by verifying the legal fineness and the application of the hallmark alongside the manufacturer's responsibility mark or equivalent. The application of hallmarks is only mandatory on pieces weighing more than 2 grams.
All consumers can verify the authenticity of each mark at the INCM.
