In Portugal, jewelry making is regulated by some of the most stringent standards in the European Union. All pieces in silver, gold, or platinum must be certified by an official entity, guaranteeing the consumer the authenticity of the precious metal and its fineness. This hallmark ensures independent control, holding both the producer and the verifier of the metal's purity accountable.

At M by Monica, all pieces follow this process and are marked by the Portuguese Assay Office.
