LUSIJOIA presents a Variety of Jewelry in our 19k and 9k, only in our Portuguese language. To observe the search for jewelry in Portuguese Lei Prata, we reaffirm our jewelry display with these precious metals. All parts are clearly marked in the Contrastarias Portuguesas of INCM - Imprensa Nacional da Casa da Moeda.

When browsing our site, in the selection of a product, each item has an express indication of two carats of gold or color, weight and any gemological material is also presented separately. See the box of Trademarks available at Casa da Moeda.


In case of doubt about the authenticity of the jewelry, the buyer can verify by contacting Contrastarias services. INCM also has a list of registered guarantors for consultation:
