OMNIA`s pieces are made in 925 silver, 925 silver with gold plated, or 9 or 19 karat gold, meeting all quality criteria and duly certified by INCM – Oporto Assay Office.

“INCM Assay Offices provide this guarantee through the verification of the legal touch (permilage of precious metal contained in an alloy) and the assay office mark application close to the punction together with the responsibility mark of the manufacturer or equivalent”, explains INCM on its website.

Punction application is mandatory in pieces weighing more than 2 grams silver and more than 1gr. gold. Thus, in a daily basis, after the production process is completed, most of the pieces are sent to the assay office so that, after their evaluation, they can be commercialized.
