LUSIJOIA produces and markets articles containing precious metals such as gold, silver, and palladium, resulting in 19-karat gold, 9-karat gold, and 925 sterling silver jewelry. Before these items are offered for sale to the consumer, they are mandatorily taken daily to be hallmarked by the Portuguese Assay Offices of the INCM - Imprensa Nacional da Casa da Moeda (Portuguese Mint).

When browsing our website, when choosing a product, each piece of jewelry clearly indicates the gold karatage or silver fineness, the weight, and any gemological material, if the piece features it. See the Hallmark chart provided by the Portuguese Mint

In case of any doubts regarding the authenticity of the jewelry, the buyer may verify it by using the services of the Assay Offices. The INCM also provides a list of registered appraisers for consultation:
