Certification and Warranty

We are aware that shopping online can sometimes be intimidating, so we do everything we can to ensure customers feel comfortable in the purchasing process, guaranteeing the authenticity of our pieces, not only through individual official markings, but We also seek to demonstrate them exhaustively and as faithfully as possible in the photographs we provide, so that our customers know exactly what to expect when they receive their order.

Our retail license, issued by Contrastaria Portuguesa , has the nr. T0844.

All our pieces have the Portuguese Contrastaria mark, guaranteeing the metal and purity used.

However, the application of the Portuguese Assay Office mark is only mandatory on silver pieces that weigh more than 2 grams and gold pieces that weigh more than 0.5 grams .

However, all of our pieces bear the responsibility of the Craftsman/Manufacturer who produced them.
