Gold purity is a measure of how much pure gold is present in a gold item. It is typically expressed in karats (K) or as a percentage. Pure gold is 24 karats, meaning it is 100% gold. However, pure gold is quite soft and not suitable for most jewelry, so it is often mixed with other metals to create an alloy. Here are the common karat levels and their corresponding gold content:
24K: 100% pure gold
22K: 91.67% gold [916 Hallmarked Gold Ornaments]
18K: 75% gold
14K: 58.33% gold
10K: 41.67% gold
