The jewelry that Luna Nuova
proposes is rigorously produced using only 18
karat gold, as dictated by the best Italian jewelry-making tradition.
In the Jewelry industry, gold is usually alloyed with other metals, mainly silver and copper, in order to make it harder: gold, as a matter of fact is not a very hard metal, and it can be dented or scratched relatively easily. The gold content of an alloy is expressed in thousands or in karats (pure gold is defined as 24 karat gold): therefore 18 karat gold is an alloy in which the pure gold is 750 thousandths of the total. |

 18 karat gold is a perfect solution for the creation of beautiful jewelry. It allows the artisan to create complex and delicate designs, and as it is less rigid than alloys with a smaller gold content it is less subject to cracks. The difference in shininess between 18 karat gold, and alloys with less gold content is evident, and it is very difficult to imitate the luminous, seductive color of 18 karat gold jewelry with alloys with containing smaller quantities of gold. 18 karat gold has the right combination of hardness and malleability and allows the artisan to create jewelry while maintaining all of the color and beauty of gold.  |
