Gold purity is measured in karats, with 24K being pure gold, but it's often alloyed with other metals for strength. 18K gold is 75% pure, offering a good balance of durability and value, while 14K is more affordable and harder, ideal for everyday wear. The karat weight affects not only the color and price but also how well the piece holds up over time.
