The silver used in Catalina is 925 (in 1000 units, 925 is pure silver). All jewels meet the quality criteria and are all certified by the INCM Contractor.
INCM Contrasteries provide this guarantee when our jewels are taken to the Casa da Moeda to be contrasted, where the legal mark is verified and the legal mark of the Portuguese Contrasteries is applied together with our responsibility / manufacturer mark made with our punch.
The application of the Contrastaria mark is only mandatory on silver pieces weighing more than 2 grams. When the weight of the piece is less than 2 grams, it´s only necessary to place the manufacturer`s mark.
