All the artworks available at Resistance Gallery have an Authentication Certificate issued by the artist.
This certification of authenticity identifies the artist, artistic name, title, technique, dimensions, creation date and the date of the first sale. This certificate is signed at the bottom by the artist and the buyer.
As a suggestion, the artist invites the buyer to document when the artwork is sold, keeping a historical register.
The artist asks that the certificate always accompanies the artwork.
All the Jewels available at Resistance Gallery are certificated by the Assay Office (Contrastaria) of INCM, the National Print and Mint House (Imprensa Nacional Casa da Moeda).
In order to guarantee the authenticity of the precious metals and their purity, the Assay Office tests and hallmarks all the jewels with its legal hallmark. All the jewels are also hallmarked with the unique makers’ mark of responsibility.
If any doubt persists about the hallmark of any jewel, you can contact us at geral@galeriaresistencia.com or the Assay Office directly (Contrastaria da INCM).
You can see here the hallmarks of the Portuguese Assay Office.
Here are the daily prices on precious metals.
