The word Karats as it applies to gold is a way of measuring the pureness of gold jewelry. The pure gold metal is so soft in its pure form and unsuitable for wearing it is often added with other metals to make it stronger. For example 24 karat gold is pure gold and as such is very soft. Gold in this state is easily malleable and would bend and change shape every time you wear it.
