We do not use recycled gold (from other jewelry) in the production process. The alloys used do not contain nickel and are in accordance with the directive of the European Parliament, 94/27/EC of March 24, 2005.
The hardness of the alloy gives 18Kt gold a mechanical resistance similar to that of gold with lower Karat.
Solders do not contain cadmium. In the technological process of manufacturing FIRESC jewelry, only solders made with the help of a special laser are used.
