In its pure form, gold is naturally yellow in colour. In jewellery and watchmaking, it is combined with other metals to form alloys. Their composition and proportions make it possible to produce different colours of gold, each with their own characteristics.
3N yellow gold is made up of 75% gold, 12.5% silver and 12.5% copper. Its luminous hue reveals the natural colour of gold.
5N rose gold combines 75% gold with 6% silver and 19% copper. The higher proportion of copper creates its signature tone of pink.
White gold, or palladium grey gold, consists of 75% gold, 10% copper and 15% palladium. A thin layer of rhodium enhances its shine and lustre. A rare metal belonging to the platinum group, palladium also contributes to the strength of this alloy.
Alloying gold provides other beneficial properties in addition to colour. In its pure form, gold is particularly malleable and is more prone to getting deformed or scratched. When combined with other metals, it becomes more durable and therefore better suited to making jewellery for everyday wear.
Yellow gold, rose gold and white gold offer different expressions of this jewellery. Yellow gold captivates with its warm lustre. Rose gold has a soft and contemporary sheen, especially suited to engagement rings. White gold shines with a bright and timeless elegance.
