Cartier mainly uses 18k gold as the main material to make ornaments, including gold, platinum, palladium and other materials. 18k gold refers to a gold alloy with a gold content of 75%, which has higher hardness, less wear and higher plasticity than gold. Besides 18k gold, platinum, palladium and other materials are also widely used. Platinum can keep bright luster for a long time because of its grayish white, stable properties and strong corrosion resistance. Another classification of platinum is palladium, which is as resistant to corrosion as platinum.
