At Torse, only 18 Karat gold is used, i.e. 750°/°° fine gold, available in three colours:

 Yellow gold. Composed of gold (75%), silver (12.5%) and copper (12.5%), proportions that yield the most beautiful yellow gold colour.

 Rose gold. Composed of gold (75%), silver (6%) and copper (19%), proportions that yield the most beautiful rose gold colour.

White gold, also known as palladium white gold 13% is composed of gold (75%), palladium (13%) and silver (12%), and covered with a thin layer of rhodium.

This rare hypoallergenic metal belonging to the platinum family gives white gold a unique lustre, brightness and shine. This jewellery needs to be handled with care, and can benefit from another rhodium bath after several years to regain its original lustre
