The quality of gold is measured by a rating known as carats. This is why gold items are stamped with 10k, 14k, 18k, etc. Gold with a higher carat rating has more gold content than gold with a lower carat rating. For example, 14k gold is roughly 58 percent gold content, 18k gold is roughly 75 percent gold content and 24k gold is pure gold.
