Gold is the absolute oldest of all metals. It doesn't corrode, tarnish or rust, so you can count on it to always stay gorgeous. Despite being a strong metal, it is still more "flexible" than the other precious metals. To keep gold solid and suitable for jewelry, pure gold is commonly mixed with different metals to increase its strength.

Yellow gold is the most common form of gold found in jewelry and is usually mixed with copper and silver. Its color depends upon the amount of pure gold in the alloy.
