The purity of gold is a measurement of how much actual gold is in a piece of jewelry or a bar.
It is measured in "Karats" (k), where 24K is the purest form.
Think of purity like a 24-slice pie where, the number of slices determine where how much gold there is. Higher number of slices means more GOLD and the fewer number of slices means less GOLD.
