Since pure gold is very malleable, it is always used as an alloy to increase its resistance. The alloy can also change the natural yellow hue of pure gold to obtain white, gray or pink gold.
For its creations, the Maison uses 18-carat or 750/1000 gold, an alloy composed of 75% pure gold which ensures that the gold does not change shape or deteriorate, and that prevents air or water oxidization.
