Joalharia do Carmo was the pioneer in the pilot project of the Imprensa Nacional-Casa da Moeda - UniqueMark® Digital Certificate - which brings to the digital age the process of certification of precious metals, in what is the oldest form of consumer protection.
Issued by a secure platform, this certificate provides a unique experience to the consumer, guaranteeing the authenticity of the jewelry through a simple smartphone. Through the official Assay Office App, the UniqueMark® Digital Certificate provides a comprehensive view of the jewellery, from the laboratory test to the affixing of the hallmark mark.
This innovative project adds value and confidence to the end consumer, protects against counterfeits, ensuring the authenticity of the jewelry and preserving the continuity of the artisanal profession, reflecting the true commitment to social economy of Joalharia do Carmo.
Each jewel has a tag and a card with a unique cryptographic code, ensuring the traceability and legitimacy of the pieces.
