Why is pure gold not used for wedding rings?

Pure gold is typically not used for wedding rings due to its properties. Because it contains no base metals, pure or 24-karat gold is soft and malleable. As a result, it's vulnerable to scratches and breakage. Alloys like 18- and 14-karat gold tend to be stronger and are better suited to making rings.
