Certification and Hallmarking

The Filigrana de Portugal certification guarantees that each piece is handcrafted, produced by recognized artisans, protecting it from industrial imitations that distort its essence.

The certification is awarded by ACERTIFICA, the Portuguese body accredited to certify traditional artisanal products.

At Ourivesaria Arneiro 1969, we work with certified artisans who produce 100% handmade pieces. An example of this is Inês Barbosa, a goldsmithing brand that is a reference in Portuguese filigree.

The first Digital Certificate from the Portuguese Assay Office, launched by the National Printing Office-Mint. It does not replace traditional marking, but complements it with a layer of digital security.
