All jewellery from Mumnoke is certified by Contrastaria of INCM (Imprensa Nacional Casa da Moeda), which verifies the legal touch, meaning the precious metal content in an alloy, and applies the hallmark alongside the responsibility mark of the manufacturer or equivalent. The application of marks is only mandatory for silver pieces weighing over 2 grams. The buyer can always, in case of doubt about the authenticity of the pieces, resort to the services of the Assay Offices for the purpose of verifying the authenticity of the material.
